A new species and a new provincial record of the genus Acidota Stephens from China (Coleoptera, Staphylinidae, Omaliinae).

New taxonomic and faunistic data for two species of the genus Acidota Stephens, 1829 from China are provided. A new species from Xizang (Linzhi) is described and illustrated: A.dawai Peng & Chen, sp. nov. Additional data (including photographs of the habitus and the type labels) on the type specimens of taxa described from Japan (A.crenatajaponica Watanabe, 1990) and Taiwan (A.montana Smetana, 1993 and A.nivicola Smetana, 1993) are given. A key to Chinese species of Acidota is given. Acidotacrenata (Fabricius, 1792) is recorded from Heilongjiang for the first time.

Four new Parasterope (Ostracoda, Myodocopina) from the Northwest Pacific and their phylogeny based on 16S rRNA.

Parasterope Kornicker, 1975 is a marine ostracod genus with 49 species described so far, which makes it the most diverse representative of the subfamily Cylindroleberidinae, as well as the entire family Cylindroleberididae. Despite its global distribution no species are reported from South Korea. Three new species collected from the Korean coast of the Sea of Japan (Parasteropebusanensis sp. nov., P.singula sp. nov., and P.sohi sp. nov.), and one from the Japanese coast of the Pacific Ocean (P.sagami sp. nov.) are described. A taxonomic key to all named species from East Asia is provided. A phylogenetic tree is reconstructed based on partial 16S rRNA sequences of the four new species and other Cylindroleberidinae available from GenBank. Monophyly of Parasterope is supported by high posterior probabilities, but the phylogenetic analyses also indicate that some of the GenBank data attributed to this genus are probably misidentifications. A map of distribution and a checklist of all described Parasterope species are also provided.

Redescription of Anchoviella cayennensis (Puyo, 1945) (Clupeiformes: Engraulidae), with the synonymization of Anchoviella sanfranciscana Barbosa, Gomes da Silva, da Rocha Araújo & Carvalho, 2017 and remarks on Anchoviella perfasciata (Poey, 1860).

Anchoviella cayennensis (Puyo, 1945) is a relatively small-sized, coastal and estuarine western Atlantic species of anchovy distributed from Suriname to southeastern Brazil. The species is morphologically similar to Anchoviella perfasciata (Poey, 1860) from the Central and western North Atlantic, and it has been suggested in the literature that both are actually synonyms. The recently described Anchoviella sanfranciscana (Barbosa et al., 2017) was reported as endemic to the estuary of the São Francisco River, northeastern Brazil. Most characters proposed as diagnostic for A. sanfranciscana in the description are, however, similar to the ones reported for A. cayennensis and A. perfasciata. To determine the complex taxonomic scenario involving the three species, 24 morphometric and 13 meristic characters of 171 specimens tentatively identified as A. perfasciata (including the holotype) and A. cayennensis from the Central and South Atlantic in addition to the holotype and 19 paratypes of A. sanfranciscana (total: 191 specimens) were analysed. The PCAs of morphometric characters indicate the existence of two groups, which are recognized as A. perfasciata and A. cayennensis, with A. sanfranciscana proposed as a junior synonym of the later. Further evidence from gill arch dentition also indicates that A. perfasciata and A. cayennensis are distinct valid species. A redescription of A. cayennensis is presented, with a neotype proposed for the species. Confirmation of the identity of specimens attributed to A. cayennensis indicates that its southern limit of distribution is in the Rio de Janeiro State, southeastern Brazil. An updated taxonomic key for the estuarine and coastal Atlantic species of Anchoviella is also presented.

Microscopic characterization of petiole anatomy of Asteraceous taxa of Western Himalaya-Pakistan.

Petiole anatomy of 15 species of family Asteraceae was examined which aimed to investigate petiolar anatomical structures for species level identification. Shandon Microtome was used for petiole histological preparations. Both qualitative and quantitative features were studied under microscope which showed significant variation in petiole, collenchyma, parenchyma shape/size, vascular bundles arrangement/size, and vessel elements quantity. Artemisia japonica Thunb., Cirsium vulgare (Savi) Ten., Myriactis nepalensis Less., Seriphidium brevifolium Ling & Y.R.Ling, Taraxacum officinale (L.) Weber ex F.H.Wigg., and Xanthium strumarium L. showed winged petioles. Maximum length and width of upper and lower epidermis was found in Tagetes erecta L. which is 23.05 ± 0.89 µm, 24.9 ± 1.257 µm length and 21.75 ± 1.38067 µm, 22.75 ± 0.467 µm width, respectively. Petioles of Parthenium hysterophorus L. was longest one with 9.85 ± 10.45 µm while A. japonica Thunb. showed highest number of vessel elements. Maximum size of vascular bundles was found in T. erecta L. with 5.05 ± 14.25 µm. Artemisia annua L., C. vulgare (Savi) Ten, Cyanthillium cinereum (L.) H.Rob., Helianthus annus L., M. nepalensis Less., P. hysterophorus L., Senecio chrysanthemoides DC. have trichomes while Tussilago farfara L. has highest number of vascular bundles. All species have angular collenchyma type except M. nepalensis Less., P. hysterophorus L., S. brevifolium Ling & Y.R.Ling, Tagetes minuta L., T. officinale L., S. chrysanthemoides DC., and T. farfara L. Cluster analysis implemented that distinct plant species in cluster. Petiolar anatomical structures and taxonomic key will helpful for distinguishing Asteraceous taxa at genus and species level. This taxonomic significant investigation will also provide baseline to taxonomists for other Asteraceae studies and phylogenetic research.

A pictorial key for identification of the hoverflies (Diptera: Syrphidae) of the Madeira Archipelago.

Background: Syrphid flies are important ecological indicators and provide crucial ecosystem services, being important pollinators and biological control agents of insect pests. These charismatic insects are conspicuous and, due to their size and colourful patterns, are relatively easy to identify. However, the lack of user-friendly literature (e.g. photographic guides) for most areas may hamper its wider selection as a study group in biodiversity and ecological studies. The syrphid fauna of Madeira Archipelago comprises 26 species, including four endemics (Eumerushispidus Smit, Aguiar & Wakeham-Dawson, 2004; Melanostomawollastoni Wakeham-Dawson, Aguiar, Smit, McCullough & Wyatt, 2004; Myathropausta, Wollaston, 1858 and Xanthandrusbabyssa, Walker, 1849), but, despite the current good taxonomic knowledge on this group, information on species distribution, ecology and conservation is still lacking. Here, we provide a pictorial key to the adult hoverflies of Madeira Archipelago highlighting diagnostic characteristics and present photographs of both males and females (in dorsal and lateral views) in colour plates. The key and plates will help researchers to differentiate these species, thus encouraging the use of this insect group in future bioindication studies. In addition, this study also aims to engage a broader audience of non-experts in improving the knowledge on the distribution and ecology of Madeira syrphids. New information: We provide a checklist for the hoverflies of Madeira Archipelago and a pictorial key to help on species identification.

A new species of Sarsinebalia (Crustacea, Leptostraca) from Japan.

A new species of Leptostraca, Sarsinebaliaagoensis sp. nov., from Ago Bay, Japan is described from specimens found at a depth of 120 m. The new species differs from other known Sarsinebalia species as follows: the compound eye has three distal lobes; the anterior margin of the first antennal segment has one distal process covered with setae; and the lateral margin of pleopod 1 exopod bears 5-6 simple, robust spines. A taxonomic key to all species of Sarsinebalia is also provided.

Three new species of the Amazonian millipede genus Leptherpum (Polydesmida: Chelodesmidae)

This study concerns the millipede genus Leptherpum Attems, 1931, which contains nine valid species distributed across the Amazonian rainforest of northeastern South America. The type species L. carinovatum (Attems, 1898) is reexamined based on the type material and high-resolution photographs, including the first scanning electron micrographs of this species. The following three new species are described: Leptherpum tialaura sp. nov. from the state of Pará, Brazil; Leptherpum battirolai sp. nov. from the state of Amazonas, Brazil; and Leptherpum buenovillegasi sp. nov. from the commune of Maripasoula, French Guiana. A brief review of Leptherpum taxonomy and geographic distribution is provided, along with a key to males.

Taxonomic, morphometric and limnological assessment of the commercially important ichthyofauna of Sakhakot Stream, Malakand, Pakistan / Avaliação taxonômica, morfométrica e limnológica da ictiofauna comercialmente importante do Riacho Sakhakot, Malakand, Paquistão

The present study was conducted for the taxonomic, morphometric and limnological assessment of the commercially important ichthyofauna of Sakhakot Stream, Malakand, Pakistan. The study area was divided into three sites along the water course namely Dargai Stream, Sakhakot Stream and Shergarh Stream. Fish samples were collected randomly during January to August 2017 with the help of fish gears. A taxonomic key was designed for the collected fish specimens. Ten fish species were identified belonging to 3 orders and 4 families. Family Cyprinidae was the dominant family with seven representative species while families Siluridae, Nemacheilidae and Mastacembelidae were represented by one species each. Lower mean total length and standard length was recorded in Puntius conchonius (Hamilton, 1822) as 9.2 ± 0.6 cm and 7.3 ± 0.6 cm respectively, while highest mean total length and standard length was recorded in Mastacembelus armatus (Lacepede, 1800) as 28.1 ± 1.7 cm and 15.9 ± 2.4 cm respectively. Mean pH of the water ranged from 6.1 at Shergarh Stream in August to 8.7 at Sakhakot Stream in January. Average temperature range was recorded from 10.9 °C in January at Dargai Stream to 18.7 °C in August at Shergarh Stream. No statistically significant difference was found for temperature (p = 0.96) and pH (p = 0.14) in the three water streams. The present study will provide a baseline for the rearing and enhancement of wild stock of the commercially important ichthyofauna in the field of aquaculture and fisheries.

Comprehensive Review of Tolypocladium and Description of a Novel Lineage from Southwest China.

Tolypocladium, a diverse genus of fungicolous fungi belonging to Ophiocordycipitaceae, includes saprotrophic soil inhabitants, plant endophytes and pathogens of insects, nematodes, rotifers, and parasites of truffle-like fungi. Here, we review the research progress achieved for Tolypocladium regarding its taxonomy, species diversity, geographic distribution, host affiliations and ecological diversity. Furthermore, an undescribed taxon from China was established using morphology and multi-gene phylogeny. Tolypocladium inusitaticapitatum is introduced as a new species parasitizing ectomycorrhizal Elaphomyces species. It is diagnosed by its irregularly enlarged fertile heads and lemon, yellow-to-dark-brown, smooth and nearly cylindrical stipe. Phylogenetic analyses based on SSU, LSU, ITS, TEF1-α and RPB2 sequence data showed T. inusitaticapitatum to be an independent lineage separated from T. flavonigrum in the clade comprising T. capitatum, T. fractum and T. longisegmentatum. A key for identifying the sexual Tolypocladium species is also provided.

Morphological and molecular description of Allocreadium apokryfi sp. n. (Digenea: Allocreadiidae) from native Labeobarbus aeneus (Cyprinidae) in South Africa, including notes on its biology, evolutionary history and an updated key of African Allocreadium.

Adult trematodes of Allocreadium Looss, 1900 (Digenea) infect the intestine of mostly freshwater fishes in Asia, Europe, Africa and the Americas. During routine parasitological surveys in the Vaal River system, adult trematodes were collected from the intestine of smallmouth yellowfish, Labeobarbus aeneus (Burchell). The trematodes were confirmed to represent a member of Allocreadium and did not match any existing taxon. Therefore, they are described as a new species, Allocreadium apokryfi sp. n. The morphology of the new species most closely resembles that of Allocreadium aswanense El-Naffar, Saoud et Hassan, 1984, but it differs from it by having a bipartite internal seminal vesicle, wider eggs, a shorter intertesticular distance, an intestinal bifurcation at the ventral sucker level, a ventral sucker that is larger than the oral sucker, and a genital pore near the intestinal bifurcation or the ventral sucker. The surface topology of the new species is notably different from that of other allocreadiids. Papillae were observed in the ventral sucker and surrounding both ventral and oral suckers, but the number and arrangement of the latter were not consistent among specimens. The protruding cirrus of A. apokryfi sp. n. was described using SEM and is the first such observation for the genus. Genetic characterisation showed that the new species was clearly distinct from other Allocreadium spp. using both 18S (nucleotide difference 1.3-9.1%) and 28S (4.7-6.5%) rDNA, forming a well-supported clade in Allocreadium. The presence of A. apokryfi sp. n. in a well-studied river is unexpected, and considering the diet of its host and the scarcity of Allocreadium in Africa, the possible biology of this species is discussed herein.

Discovery of the braconid subfamily Dirrhopinae van Achterberg (Hymenoptera: Ichneumonoidea) from the Indian subcontinent with the description of a new species from south India.

The subfamily Dirrhopinae van Achterberg, 1984 is reported from the Indian subcontinent for the first time. A new species, Dirrhope indica Ranjith sp. nov. is hereby described and illustrated. An updated key to the extant species of Dirrhope is provided along with illustrations of the following species; D. eoa Belokobylskij, D. minor Belokobylskij, and D. rufa Foerster.

El número de equinodermos conocidos en la bahía de Chamela aumenta a 48 especies. Conclusiones: Se presenta el listado más completo de la clase Ophiuroidea en la bahía de Chamela, Jalisco. La información proporcionada se puede utilizar para otras áreas del Pacífico oriental. La bahía de Chamela es importante en términos de riqueza de especies debido a su heterogeneidad ambiental y numerosas islas.

Introduction: Chamela bay is located in the central portion of the coast from the Jalisco state, Mexico and is an important protected natural area. Despite this, the study of echinoderms in the area is incipient. Objective: To provide an updated checklist, descriptions of the species and a taxonomic key of the ophiuroids from Chamela bay. Methods: We collected specimens from 1998 to 2018, and also analyzed information from the literature and specimens deposited at international scientific collections from Chamela bay. Results: 19 species of ophiuroids are reported for the study area, distributed in two orders, seven families, and 11 genera. Seven of these correspond to new records for the area, one to a new record for Jalisco state, and two possibly represent new species. The biodiversity of ophiuroids in Chamela bay represents 15.2 % of ophiuroid species from the Mexican Pacific and 73 % from Jalisco. The number of known echinoderms in Chamela bay is increased to 48 species. Conclusions: The most complete checklist of the class Ophiuroidea in Chamela bay, Jalisco, is presented. The information provided can be used for other areas of the eastern Pacific. Chamela bay is important in terms of species richness due to its environmental heterogeneity and numerous islands.

A review of Gryllidae (Grylloidea) with the description of one new species and four new distribution records from the Sindh Province, Pakistan.

Seventeen species of the family Gryllidae were reviewed and a Modicogryllussindhensis is described herein as new. Four species, namely Achetahispanicus Rambur, 1838, Gryllusseptentrionalis F. Walker, 1869, Callogryllussaeedi Saeed, 2000, and Miogryllusitaquiensis Orsini & Zefa, 2017 are recorded as new country and state records. Differences between similar species and a taxonomic key to the species of Sindh are provided.

Taxonomic Study of the Genus Pholiota (Strophariaceae, Basidiomycota) in Korea.

The genus Pholiota (Strophariaceae, Basidiomycota) is made up of wood-rotting saprotrophic mushrooms characterized by a yellow or brown pileus with scales and/or slimy, and by a brownish smooth spore with a germ pore. However, these features are not enough to distinguish its species, or separate the genus Pholiota from other brown-spored wood-rotting genera such as Hypholoma and Stropharia. Although internal transcribed spacer (ITS) sequence-based identification has improved identification accuracy for species of Pholiota, most Pholiota species in Korea are reported based on morphological features. To evaluate the taxonomy of Pholiota species, we investigated 62 specimens collected from 1999 to 2019 in Korea using ITS sequence analysis and morphological observation. Twelve of the 16 recorded Pholiota species in Korea were identified. While eight species were clearly separated, the ITS analysis did not distinguish three in the Pholiota adiposa complex. Therefore, further investigation is required to distinguish these three species. ITS sequences deposited in GenBank confirm that P. highlandensis exists in Korea. The presence of the other four Pholiota species could not be confirmed through specimens or sequence information in GenBank. A taxonomic key and the ITS sequence data for Korean Pholiota species are included and can be good baselines for further research on Pholiota taxonomy and diversity.

Morphology-based taxonomic re-assessment of the Arctic lamprey, Lethenteron camtschaticum (Tilesius, 1811) and taxonomic position of other members of the genus.

The lamprey genus Lethenteron Creaser & Hubbs, 1922 is widespread across Eurasia and North America, but the number and distribution of its constituent species is not firmly established. After a morphological examination of extant type material of the currently recognized species and their synonyms, Lethenteron mitsukurii (Hatta, 1901) is resurrected with Le. matsubarai Vladykov & Kott, 1978 as its junior synonym. Amongst nonparasitic species Le. reissneri (Dybowski, 1869) and Le. mitsukurii are confirmed as present in Japan and the former is also present on Sakhalin. An in-depth study of large samples of nonparasitic lamprey adults from Japan and Sakhalin Island is needed to determine whether the lower trunk myomere (< 66) individuals from these areas represent one or more undescribed species, or Le. mitsukurii, or Le. reissneri, or a mixture of these three alternatives. The material from the Anadyr Estuary identified by Berg (1931, 1948) as Lampetra japonica kessleri has been re-identified as Le. camtschaticum and there is no evidence that Le. kessleri occurs there. Lethenteron reissneri is reported from the Angara River system, Yenisei River drainage, Russia. Lethenteron alaskense Vladykov & Kott, 1978 is provisionally considered to be a junior synonym of Le. kessleri (Anikin, 1905). Petromyzon ernstii Dybowski, 1872, Ammocoetes aureus Bean, 1881, Petromyzon dentex Anikin, 1905, Lampetra mitsukurii major Hatta, 1911, and Lampetra japonica septentrionalis Berg, 1931 are junior synonyms of Petromyzon marinus camtschaticus Tilesius, 1811. A key is provided to adults of the six species recognized as belonging in the genus Lethenteron.

A new subterranean species and an updated checklist of Strumigenys (Hymenoptera, Formicidae) from Macao SAR, China, with a key to species of the Greater Bay Area.

In the past few decades, sampling of leaf litter with Winkler extractors revealed how abundant and ubiquitous ants from the genus Strumigenys are. It is now known that this genus has the third greatest number of species within the Formicidae family. However, very few subterranean species are known, which may be due to the current under-sampling of the soil stratum. Here, a holistic sampling approach, including the use of subterranean traps, was employed in Macao SAR, China. Subterranean traps allowed the collection of a new cryptic ant species: Strumigenys subterranea Brassard, Leong & Guénard, sp. nov. Moreover, extensive sampling of the leaf litter in secondary forests provided four new species records for the genus. The list of Macanese Strumigenys is here updated, elevating the known diversity in Macao to nine species. Furthermore, to facilitate further research on ants of the Guangdong-Hong Kong-Macao Greater Bay Area, a key to the 29 Strumigenys species known from the region is provided. Lastly, recommendations for sampling methods to assess ant biodiversity underground are discussed. In conclusion, this study highlights the importance of using extensive sampling methods, and suggests that relatively small patches of secondary forests within cities can hold a surprisingly high diversity as well as some undescribed species.

A new black fly species of Simulium (Nevermannia) (Simuliidae: Diptera) from the Southern Eastern Ghats, India.

A new black fly species, Simulium (Nevermannia) karavalliense sp. nov. is described from Southern Eastern Ghats of South India. This new species is placed in the Simulium ruficorne species-group of the subgenus Nevermannia. S. (N.) karavalliense sp. nov. is characterized by female with a long sensory vesicle, male upper eye with 14 vertical columns and 16 horizontal rows of large facets, pupal gill with 8 filaments and larval hypostoma with 6 hypostomal bristles lying parallel to lateral margin. Taxonomic keys are provided to distinguish this new species from related species in India.

A new species of Toccolosida, a Pyralinae from the Western Ghats, India (Lepidoptera, Pyralidae) and the revised status of Lixa as a synonym.

A new species, Toccolosida ganeshgudiensis N. Singh, Kirti Ranjan, sp. nov. is described from the Western Ghats of Karnataka, India, the furthest southern known distribution for the genus in India. Additionally, Lixa Walker, 1866 is synonymised with Toccolosida Walker, 1863 and L. productalis Walker is newly combined as Toccolosida productalis (Walker), comb. nov. An updated checklist and a taxonomic key to the known species of Toccolosida are also provided.
