Historical Biogeography of Earwigs.

The Dermaptera are an insect order exhibiting their highest diversity in the tropical areas of the southern hemisphere. This pattern has been considered a reflection of a Gondwanan origin. However, this hypothesis has not been tested through analytical methods. In this paper, the world distribution of earwigs was analysed by using the 'Cladistic Analysis of Distributions and Endemism' (CADE), a method which groups areas of endemism on the basis of shared distributions and phylogenetic relationships among taxa. In addition, clustering techniques were applied to depict biotic relationships based on similarity indices. Results of CADE support the idea that Gondwanan fragmentation exerted a crucial role in shaping the current distribution of the main clades of earwigs. However, the relationships between India with South East Asia suggested a biotic interchange occurred after the Indian collision with the Eurasian plate. The overall scenario emerging from cluster analyses revealed a strong influence of dispersal events. Overall, the distribution of earwig major clades indicates that their biogeographical history was mainly characterized by vicariance events (led by the break-up of Gondwana) followed by large scale dispersal processes constrained by the Himalayan orogenesis and the presence of colder temperatures, which have largely hampered the colonization of the northern hemisphere.

Taxonomic revision and cladistic analysis of the tarantula genera Tapinauchenius Ausserer, 1871, Psalmopoeus Pocock, 1985, and Amazonius n. gen. (Theraphosidae, Psalmopoeinae)

The genera Psalmopoeus Pocock, 1895, Tapinauchenius Ausserer, 1871 and Pseudoclamoris Hüsser, 2018 are revised and cladistics analyses carried out including most species of these genera. In order to test the monophyly of Aviculariinae and Psalmopoeinae, species of all genera in these two subfamilies were included, as well as of Harpactirinae, Selenocosmiinae, Theraphosinae, Stromatopelmatinae, Ischnocolinae, Schismatothelinae, Poecilotherinae, and a barychelid was used to root the cladogram. The matrix with 50 terminal taxa, 1 continuous and 85 discrete characters was analysed with TNT 1.5. The results show a monophyletic Psalmopoeinae as sister group of Aviculariinae. Psalmopoeus comprises 9 species: Psalmopoeus cambridgei Pocock, 1895 (type species), Psalmopoeus ecclesiasticus Pocock, 1903, Psalmopoeus emeraldus Pocock, 1903, Psalmopoeus irminia Saager, 1994, Psalmopoeus langenbucheri Schmidt, Bullmer & Thierer-Lutz, 2006, Psalmopoeus plantaris Pocock, 1903, Psalmopoeus pulcher Petrunkevitch, 1925, Psalmopoeus reduncus (Karsch, 1880), and Psalmopoeus victori Mendoza, 2014. Psalmopoeus intermedius Chamberlin, 1940 is considered a junior synonym of P. reduncus. Psalmopoeus copanensis Gabriel & Sherwood, 2020, P. sandersoni Gabriel & Sherwood, 2020 and P. petenensis Gabriel & Sherwood, 2020 are considered junior synonyms of P. victori. Psalmopoeus maya Witt, 1996 is considered nomen nudum. Tapinauchenius comprises 8 species: Tapinauchenius plumipes (C. L. Koch, 1842) (type species), Tapinauchenius sanctivincenti (Walckenaer, 1837), Tapinauchenius latipes L. Koch, 1875, Tapinauchenius brunneus Schmidt, 1995, Tapinauchenius cupreus Schmidt & Bauer, 1996, Tapinauchenius polybotes Hüsser, 2018, Tapinauchenius rasti Hüsser, 2018, and T. gretae n. sp. The female of T. brunneus is described for first time. Tapinauchenius violaceus (Mello-Leitão, 1930), T. purpureus Schmidt, 1995, T. concolor (Caporiaccco, 1947), and T. gigas Caporiacco, 1954 are considered junior synonyms of T. plumipes. With the synonymy of T. gigas (type species of Pseudoclamoris Hüsser, 2018), it was necessary to describe a new genus for the two species formerly included in it. Thus, the new genus Amazonius n. gen. is erected to include A. elenae (Schmidt, 1994) n. comb., A. burgessi (Hüsser, 2018) n. comb. as well as two new species A. giovaninii n. gen. n. sp. and A. germani n. gen. n. sp. A discussion on the relationship of Psalmopoeinae and Aviculariinae and maps with the distributions of all species are provided.

First report of the genus Bicorniphontodes (Copepoda, Harpacticoida, Ancorabolidae) in South Korea, with descriptions of three new species.

We report the occurrence of the genus Bicorniphontodes George, Glatzel & Schröder, 2019 in Korean waters, with descriptions of three new species: Bicorniphontodes lacuna sp. nov., B. comptus sp. nov., and B. huysi sp. nov. Morphology analysis was carried out to reconstruct the phylogenetic relationships of Bicorniphontodes species, including the three new species. Parsimony analysis based on 41 characters revealed that the three new species are clustered together as a monophyletic clade, of which B. horstgeorgei (George & Gheerardyn, 2015) is a sister species. The monophyletic status of three new species was supported by five synapomorphies, such as the micro-morphological conditions of the exopodal segments of the first leg, coxae of the second to fourth legs, exopod of the fifth leg in the female and baseoendopod of the fifth leg in the male, and the maxillular endopod represented by two setae. These three species can be easily distinguished based on the morphology of the rostrum, cephalothoracic processes, female genital double-somite, caudal rami, and second endopodal segment of the third leg in the male. The taxonomic position of B. bicornis sensu Kim, 2013 in Korean fauna was reevaluated based on the newly collected material from Udo Islet near Jeju Island; this resulted in a synonym of B. huysi sp. nov.

Phylogenetic systematics of the genera of Thryptocerina Jeannel, 1949 and new species from New Caledonia (Coleoptera, Carabidae, Oodini).

The Oodini precinctive to New Caledonia are reviewed with nine species recognized, of which seven are newly described in two genera. Five species are described in the genus Coptocarpus Chaudoir: C. microps sp. nov., C. erwini sp. nov., C. amieuensis sp. nov., C. magnus sp. nov., and C. lescheni sp. nov. In the genus Adelopomorpha Heller two species, A. tethys sp. nov. and A. tuberculata sp. nov., are described. In order to place cladistically the newly described species in a genus, a phylogenetic analysis of a matrix of 36 characters of adult morphology was conducted including exemplar species of three putative outgroup genera, six putative ingroup thryptocerine oodine genera, and all oodine species from New Caledonia. Results show support for Thryptocerina and monophyly of Adelopomorpha. Hoplolenus LaFerté-Sénectère is not monophyletic and Hoplolenus cyllodinus Fauvel is newly combined as Coptocarpus cyllodinus comb. nov. New Caledonian species of Coptocarpus form a clade, but the Australian species of the genus included in the analysis are rendered paraphyletic by African and Malagasy genera. Implications of this preliminary study for the classification of Oodini and trends in the evolution of the female reproductive tract are discussed. A key to the New Caledonian species of Oodini is provided.

Revision and cladistic analysis of Psalistops Simon, 1889, Trichopelma Simon, 1888 and Cyrtogrammomma Pocock, 1895 (Araneae: Theraphosidae) based on a cladistic analysis of relationships of Theraphosidae, Barychelidae and Paratropididae.

The genera Psalistops Simon, 1889, Trichopelma, Simon, 1888 and Cyrtogrammomma Pocock, 1895 are revised and included in cladistics analyses including almost all species of these genera. In order to test previous morphological hypotheses on the relationships of Barychelidae, Paratropididae and Theraphosidae and because of the controversial taxonomic position of Psalistops and Trichopelma, a set of terminal taxa representing all subfamilies of Paratropididae (Paratropidinae, Glabropelmatinae), Barychelidae (Barychelinae, Sasoninae, Trichopelmatinae) and most theraphosid subfamilies were included, as well as a diplurid, a nemesiid, and a pycnothelid, the later used to root the cladogram. The matrix with 66 terminal taxa, 2 continuous and 93 discrete characters was analysed with TNT 1.5. We found that Trichopelmatinae is not a monophyletic group, and Psalistops is transferred to Theraphosidae, as well as the barychelid genus Cyrtogrammomma and the paratropidid genus Melloina Brignoli. Cyrtogrammomma was retrieved as the sister group of Trichopelma, and Melloina as the sister group of Holothele Karsch. Psalistops was retrieved as the sister group of Reichlingia Rudloff, and the clade with these two genera is the most basal in Theraphosidae. Barychelidae was found to be monophyletic and the sister group of Theraphosidae. Paratropididae was retrieved as the sister group of Barychelidae + Theraphosidae. The relationship and possible synapomorphies of the three families are herein discussed.                This is the first time since Raven (1985) that representatives of all barychelid (Barychelinae, Sasoninae, Trichopelmatinae), paratropidid (Paratropidinae, Glabropelmatinae) and most theraphosid subfamilies have been included in a morphological cladistic analysis.                Psalistops comprises two species, P. melanopygius Simon, 1889 (type species) and P. colombianus sp. nov. Psalistops montigena Simon, 1889, P. tigrinus Simon, 1889 and P. zonatus Simon, 1889 are synonymized with P. melanopygius Simon, 1889. Psalistops fulvus Bryant, 1948, P. hispaniolensis Wunderlich, 1988 (fossil), P. maculosus Bryant, 1948, P. venadensis Valerio, 1986 and P. steini (Simon, 1889) are transferred to Trichopelma. Psalistops gasci Maréchal, 1996 is transferred to Hapalopus Ausserer (Theraphosidae); P. opifex (Simon, 1889) and P. solitarius (Simon, 1889) are transferred to Schismatothele Karsch, 1879 (Theraphosidae). Schismatothele solitarius (Simon, 1889) n. comb. is synonymized with Schismatothele lineata Karsch, 1879, n. syn. Psalistops nigrifemuratus Mello-Leitão, 1939 is probably a nemesiid or pycnothelid, and herein considered as nomen dubium in Pycnothelidae. Trichopelma comprises 22 species: Trichopelma nitidum Simon, 1888 (type species), T. coenobita (Simon, 1889), T. steini (Simon, 1889), T. affine (Simon, 1892), T. cubanum (Simon, 1903), T. maculatum (Banks, 1906), T. zebra (Petrunkevitch, 1925), T. banksia Özdikmen Demir, 2012, T. insulanum (Petrunkevitch, 1926), T. fulvus (Bryant, 1948) n. comb., T. laselva Valerio, 1986, T. venadensis (Valerio, 1986) n. comb., T. huffi sp. nov., T. gabrieli sp. nov., T. tostoi sp. nov., T. goloboffi sp. nov., T. juventud sp. nov., T. laurae sp. nov., T.bimini sp. nov., T. loui sp. nov., T. platnicki sp. nov., and T. hispaniolensis Wunderlich, 1988 n. comb. (fossil). Trichopelma maculosus (Bryant, 1948) n. comb. is synonymized with P. fulvus Bryant, 1948; T. corozalis (Petrunkevitch, 1929) is synonymized with T. insulanum (Petrunkevitch, 1926).

Trichopelma flavicomum Simon, 1891 is transferred to Neodiplothele (Barychelidae, Sasoninae). The species T. illetabile Simon, 1888, T. spinosum (Franganillo, 1926), T. scopulatum (Fischel, 1927) and T. eucubanum Özdikmen Demir, 2012 are considered as nomina dubia. Cyrtogrammomma comprises two species: C. monticola Pocock, 1895 (type species) and C. raveni sp. nov.

Revision of the Oriental species of Polypedilum Kieffer (Diptera: Chironomidae) with their phylogenetic relationship.

(Tripodura) conghuaense Zhang, Song, Qi and Wang, 2016 with pupa are recorded firstly in the subcontinent. Hypopygia of P. (P.) ascium Chaudhuri, Guha and Das Gupta, 1981, P. (T.) conghuaense, P. (T.) lineatum Chaudhuri, Guha and Das Gupta, 1981 and P. (P.) nudiceps Chaudhuri, Guha and Das Gupta, 1981 are redescribed. Polypedilum (P.) exterflexum Hazra, Sanyal and Brahma, 2015, P. clavipennae Hazra, Sanyal and Brahma, 2015 and P. aduncum Konar and Hazra, 2017 are proposed here to transfer to the genus Stictochironomus Kieffer, 1919. Polypedilum (P.) insolitum Chaudhuri, Guha and Das Gupta, 1981 is here stated as junior synonym of Zavreliella marmorata (Wulp, 1859). In addition, some biogeographic and taxonomic remarks including DNA barcoding for selected species are given. Cladistic analysis of the Oriental species of Polypedilum Kieffer is made to hypothesise their possible relationship. A new dichotomous key of the Oriental species of Polypedilum is presented here.

A new species of the genus Larsia Fittkau (Diptera: Chironomidae) from India, with cladistic analysis and a world key to the known males.

A new species of the genus Larsia Fittkau, 1962 is described based on the adult males. It is the first species of this genus reported from India and second member from the Oriental region. The DNA barcode of this new species is provided. The cladistic analysis of the known species of Larsia using morphological data of both immature and male adult stages have supported monophyly of the genus. A world key to the known males of the genus Larsia is presented here.

Phylogenetic analysis of the Taeniothrips genus-group, with revision of the species of Ctenothrips and Vulgatothrips (Thysanoptera, Thripinae).

The pattern of relationships within the Taeniothrips genus-group was examined using a morphological phylogenetic analysis. Genera comprising this group are discussed together with some character states used in the analysis. Taeniothrips genus-group is recovered as monophyletic, but Taeniothrips appears to be polyphyletic. Ctenothrips is here interpreted as sister-group to Vulgatothrips, with Ctenothrips smilax and C. dissimilis transferred to Vulgatothrips, and C. niger synonymized with C. smilax. Diagnoses of Ctenothrips and Vulgatothrips are presented with illustrated keys to distinguish these genera and their included species, and eight species are newly synonymised in Ctenothrips.

Ultrastructural Studies on a Model Tintinnid - Schmidingerella meunieri (Kofoid & Campbell, 1929) Agatha & Strüder-Kypke, 2012 (Ciliophora). II. The Oral Apparatus.

The ultrastructure of the oral apparatus is supposed to be significant for elucidating more recent common ancestry and might thus provide support for particular groupings of oligotrichean ciliates. The transmission electron microscopical study on mainly cryofixed Schmidingerella meunieri specimens provides the first detailed data for tintinnids and Oligotrichea in general. Ten new characters are included into the cladistic analysis. These features together with the very limited body of literature suggest that substantial changes in the oral ultrastructure correlate only with the formation of a circular adoral zone in choreotrichids. Despite homoplasious morphological and ontogenetic adaptations to the planktonic lifestyle in halteriid hypotrichs and oligotrichids, their oral apparatuses generally retain the plesiomorphic ultrastructure of the Perilemmaphora. The highly complex ultrastructure of the adoral zone is thus able to accomplish an extension in the zone's functionality without obvious changes; only the position of the adoral zone at the apical cell portion together with a globular to obconical cell shape are apparently crucial. Merely, minute apomorphies characterise the Oligotrichea and tintinnids, respectively. Tintinnids with derived somatic ciliary patterns possess distinct microtubular bundles connecting the oral apparatus with the myoneme in the peduncle.

The world woodlouse flies (Diptera, Rhinophoridae).

The world Rhinophoridae are catalogued, recognising 33 genera and 177 species. Nomenclatural information is provided for all genus-group and species-group names, including lists of synonyms and name-bearing type data. Species distributions are recorded by country. A key to the world genera is presented. Four new genera are erected to accommodate five new species, which do not fit within any of the current generic concepts in Rhinophoridae, according to the results of a morphology-based phylogenetic analysis: Marshallicona Cerretti & Pape with type species Marshallicona quitu Cerretti & Pape, gen. et sp. nov. (Ecuador); Maurhinophora Cerretti & Pape with type species Maurhinophora indoceanica Cerretti & Pape, gen. et sp. nov. (Mauritius); Neotarsina Cerretti & Pape with type species Neotarsina caraibica Cerretti & Pape, gen. et sp. nov. (Trinidad and Tobago) and Neotarsina andina Cerretti & Pape, sp. nov. (Peru); Kinabalumyia Cerretti & Pape with type species Kinabalumyia pinax Cerretti & Pape, gen. et sp. nov. (Malaysia, Sabah). The genus Aporeomyia Pape & Shima (type species Aporeomyia antennalis Pape & Shima), originally assigned to Tachinidae, is here reassigned to Rhinophoridae based on a reassessment of the homologies of the male terminalia. The following five species-group names, which were previously treated as junior synonyms or nomina dubia, are recognised as valid species names: Acompomintho caucasica (Villeneuve, 1908), stat. rev. [from nomen dubium to valid species]; Acompomintho sinensis (Villeneuve, 1936), stat. rev. [from nomen dubium to valid species]; Stevenia bertei (Rondani, 1865), stat. rev. [from nomen dubium to valid species]; Stevenia sardoa Villeneuve, 1920, stat. rev. [from junior synonym of Rhinophora deceptoria Loew, 1847 to valid species]; Stevenia subalbida (Villeneuve, 1911), stat. rev. [from junior synonym of Rhinophora deceptoria Loew, 1847 to valid species]. Reversal of precedence is invoked for the following case of subjective synonymy to promote stability in nomenclature: Rhinophora lepida (Meigen, 1824), nomen protectum, and Musca parcus Harris, 1780: 144, nomen oblitum. New generic and specific synonymies are proposed for the following two names: Mimodexia Rohdendorf, 1935, junior synonym of Tromodesia Rondani, 1856, syn. nov. and Ptilocheta tacchetti Rondani, 1865, junior synonym of Stevenia obscuripennis (Loew, 1847), syn. nov. The following new combinations are proposed: Acompomintho sinensis (Villeneuve, 1936), comb. nov. [transferred from Tricogena Robineau-Desvoidy, 1830]; Tromodesia guzari (Rohdendorf, 1935), comb. nov. [transferred from Mimodexia Rohdendorf, 1935]; Tromodesia intermedia (Rohdendorf, 1935), comb. nov. [transferred from Mimodexia Rohdendorf, 1935]; Tromodesia lindneriana (Rohdendorf, 1961), comb. nov. [transferred from Mimodexia Rohdendorf, 1935]; Tromodesia magnifica (Rohdendorf, 1935), comb. nov. [transferred from Mimodexia Rohdendorf, 1935]; Tromodesia obscurior (Rohdendorf, 1935), comb. nov. [transferred from Mimodexia Rohdendorf, 1935]; Tromodesia pallidissima (Rohdendorf, 1935), comb. nov. [transferred from Mimodexia Rohdendorf, 1935]; Tromodesia setiventris (Rohdendorf, 1935), comb. nov. [transferred from Mimodexia Rohdendorf, 1935] and Tromodesia shachrudi (Rohdendorf, 1935), comb. nov. [transferred from Mimodexia Rohdendorf, 1935].

The phylogenetic relationships of the two-winged South American Leptophlebiidae genera revisited with first description of the male imago of Bessierus Thomas amp; Orth (Insecta: Ephemeroptera).

Four of the 43 genera of South American Leptophlebiidae are dipterous. A previous phylogenetic hypothesis supported that clade Askola+Hagenulopsis, and that Bessierus+Perissophlebiodes, are sister groups of the Farrodes complex. Adults of Bessierus and Perissophlebiodes were not known but posteriorly Perissophlebiodes male imago was described. Here, we describe the male imago of Bessierus for the first time. Both genera share, besides the absence of the hind wings, the asymmetrical fork of MA, symmetrical fork of MP, dissimilar tarsal claws, and forceps sockets fused. Along with the description of the imago, a new diagnosis for the genus Bessierus is presented, also updating the identification key with this new information. A new cladistics analysis is performed to test the stability of the proposed relationships of these four genera within Leptophlebiidae. We obtained a single cladistic hypothesis where the addition of Bessierus adult characters resulted in new synapomorphies for the (Bessierus, Perissophlebiodes) clade, and improved its clade statistical support. The fused forceps sockets resulted in a synapomorphy uniting Bessierus, Perissophlebiodes and Simothraulopsis. As a result of this new analysis, the hypothesis of independent losses of the hind wings in the two dipterous groups studied is supported. The Farrodes lineage is not supported as proposed in previous studies, being restricted only to (Farrodes (Simothraulopsis, Homothraulus)) while the identity of "Perissophlebiodes lineage" is supported. The sister group relationship of Rondophlebia is not clearly defined.

Review of amphipods of the genus Cryptodius Moore, 1992 (Amphipoda: Ochlesidae) from the coastal waters of Sakhalin Island (Far East of Russia).

Based on new material, the new species of the genus Cryptodius is described: C. sakhalinensis sp. nov. from north-east shelf of Sakhalin Island. Keys to the world species of the genus Cryptodius is provided. Cladistic analysis of morphological relationships within genera Cryptodius and Odius are implemented.

Redescription of Antetintinnidium mucicola (Claparède and Lachmann, 1858) nov. gen., nov. comb. (Alveolata, Ciliophora, Tintinnina).

Tintinnid ciliates have traditionally been described and classified exclusively based on their lorica features. Although information on the cell characters is urgently needed for a natural classification, more molecular than cytological data has been accumulated over recent years. Apparently, the tintinnids developed in the marine environment and entered freshwater several times independently. Typical freshwater tintinnids belong to the genera Tintinnidium and Membranicola. The species are comparatively well-known regarding their morphology and characterised by two unusual de novo originating ciliary rows, the ventral organelles. In contrast, the cell features in the marine/brackish Tintinnidium species, specifically their somatic ciliary patterns, are insufficiently known or not known at all. Therefore, the morphology of a common marine/brackish representative, Tintinnidium mucicola, is redescribed based on live observation and protargol-stained material. Furthermore, biogeographical and autecological data of the species are compiled from literature and own records. The phylogenetic relationships of T. mucicola are inferred and the diversity of the family Tintinnidiidae is assessed from 18S rDNA sequences. The study shows that T. mucicola is not only molecularly distinct, but also characterised by many plesiomorphic features, for instance, it does not possess a verifiable homologue to the ventral organelles. Hence, a new genus, Antetintinnidium nov. gen., is established for T. mucicola. The new insights into the diversity of Tintinnidiidae shed light on the early evolution of tintinnids and might provide clues on their adaptions to freshwater.

A new leafhopper genus Discolopeus and nine new species (Hemiptera, Cicadellidae, Deltocephalinae) associated with shrubs, trees and poisonous plants in South Africa.

Nine new species in a new genus, Discolopeus gen. n. are described from south-western South Africa, with some species associated with plants that are medicinal or toxic or harmful to ungulates, such as Antizoma miersiana (Menispermaceae), Galenia africana (Aizoaceae), Hyaenanche globosa (Euphorbiaceae) and Zygophyllum foetidum (Zygophyllaceae). New species are as follows: Discolopeus arctus, D. colopeus, D. copeus, D. diacaenus, D. lissus, D. tetracaenus, D. thigmacaenus, D. triacaenus and D. viraktamathi. This new genus is allied to the Bonaspeiini, and distinguished by a paired aedeagal, preatrial process. Cladistic analyses of morphology with parsimony, Bayesian inference and maximum likelihood examined species relationships and showed the monophyly of Discolopeus. Historical biogeographic analyses examined hypotheses of dispersal and vicariance to explain distributions. Niche modelling showed narrow distribution in south-western parts of South Africa.

An algorithm for Morphological Phylogenetic Analysis with Inapplicable Data.

Morphological data play a key role in the inference of biological relationships and evolutionary history and are essential for the interpretation of the fossil record. The hierarchical interdependence of many morphological characters, however, complicates phylogenetic analysis. In particular, many characters only apply to a subset of terminal taxa. The widely used "reductive coding" approach treats taxa in which a character is inapplicable as though the character's state is simply missing (unknown). This approach has long been known to create spurious tree length estimates on certain topologies, potentially leading to erroneous results in phylogenetic searches-but pratical solutions have yet to be proposed and implemented. Here, we present a single-character algorithm for reconstructing ancestral states in reductively coded data sets, following the theoretical guideline of minimizing homoplasy over all characters. Our algorithm uses up to three traversals to score a tree, and a fourth to fully resolve final states at each node within the tree. We use explicit criteria to resolve ambiguity in applicable/inapplicable dichotomies, and to optimize missing data. So that it can be applied to single characters, the algorithm employs local optimization; as such, the method provides a fast but approximate inference of ancestral states and tree score. The application of our method to published morphological data sets indicates that, compared to traditional methods, it identifies different trees as "optimal." As such, the use of our algorithm to handle inapplicable data may significantly alter the outcome of tree searches, modifying the inferred placement of living and fossil taxa and potentially leading to major differences in reconstructions of evolutionary history.

Characterization of the mitochondrial genome of Arge bella Wei & Du sp. nov. (Hymenoptera: Argidae).

We describe Arge bella Wei & Du sp. nov., a large and beautiful species of Argidae from south China, and report its mitochondrial genome based on high-throughput sequencing data. We present the gene order, nucleotide composition of protein-coding genes (PCGs), and the secondary structures of RNA genes. The nearly complete mitochondrial genome of A. bella has a length of 15,576 bp and a typical set of 37 genes (22 tRNAs, 13 PCGs, and 2 rRNAs). Three tRNAs are rearranged in the A. bella mitochondrial genome as compared to the ancestral type in insects: trnM and trnQ are shuffled, while trnW is translocated from the trnW-trnC-trnY cluster to a location downstream of trnI. All PCGs are initiated by ATN codons, and terminated with TAA, TA or T as stop codons. All tRNAs have a typical cloverleaf secondary structure, except for trnS1. H821 of rrnS and H976 of rrnL are redundant. A phylogenetic analysis based on mitochondrial genome sequences of A. bella, 21 other symphytan species, two apocritan representatives, and four outgroup taxa supports the placement of Argidae as sister to the Pergidae within the symphytan superfamily Tenthredinoidea.

Phylogenetic study of the genus Sternolophus Solier (Coleoptera, Hydrophilidae) based on adult morphology.

The phylogeny of the hydrophilid genus Sternolophus Solier, 1834 was examined in this study using 60 morphological adult characters, eight of them continuous and 52 discrete. The cladistic analysis resulted in a single most parsimonious tree with two major subclades corresponding, respectively, to species previously assigned to the subgenera Sternolophus s. str. Solier and Neosternolophus Zaitzev, although they are not re-instated. The species groups S. angolensis (Erichson, 1843) and S. solieri Castelnau, 1840 are recovered as monophyletic. The biogeography and diversification of the species of Sternolophus are briefly discussed.

MAST-like protein kinase IREH1 from Arabidopsis thaliana co-localizes with the centrosome when expressed in animal cells.

MAIN CONCLUSION: The similarity of IREH1 (Incomplete Root Hair Elongation 1) and animal MAST kinases was confirmed; IREH1cDNA was cloned while expressing in cultured animal cells co-localized with the centrosome. In mammals and fruit flies, microtubule-associated serine/threonine-protein kinases (MAST) are strongly involved in the regulation of the microtubule system. Higher plants also possess protein kinases homologous to MASTs, but their function and interaction with the cytoskeleton remain unclear. Here, we confirmed the sequence and structural similarity of MAST-related putative protein kinase IREH1 (At3g17850) and known animal MAST kinases. We report the first cloning of full-length cDNA of the IREH1 from Arabidopsis thaliana. Recombinant GFP-IREH1 protein was expressed in different cultured animal cells. It revealed co-localization with the centrosome without influencing cell morphology and microtubule arrangement. Structural N-terminal region of the IREH1 molecule co-localized with centrosome as well.
