Yungahelea, a new genus of predaceous midge from northwestern Argentina (Culicomorpha: Ceratopogonidae)

ABSTRACT A new monotypic genus and species of predaceous midge from the southernmost area of the Argentinean Yungas, Yungahelea australis Spinelli and Ronderos, is described and illustrated from male and female adults. It belongs to a group containing the Ceratopogonini genera Parabezzia Malloch, Diaphanobezzia Ingram and Macfie, Spinellihelea Borkent, Grogan and Picado, Leptohelea Wirth and Blanton, and Fittkauhelea Wirth and Blanton. Phylogenetic interpretation indicates that Yungahelea is the sister group of Spinellihelea or the clade composed by Parabezzia and Diaphanobezzia.

Revisión taxonómica del grupo Haplothrips-Karnyothrips (Thysanoptera: Phlaeothripidae)

Taxonomic revision of the Haplothrips-Karnyothrips group (Thysanoptera: Phlaeothripidae). The generic group ("ensemble") Haplothrips-Karnyothrips is reviewed, following the most recently published criteria for distinguishing generic characters. We establish a new diagnosis for each genus. A review of a Central American collection is included and a new genus of Phlaeothripidae is described from the Central Pacific of Costa Rica from specimens collected on Cyperaceae flowers during the dry season. The genus can be distinguished by widely separated maxillary stylets, absent maxillary bridge, pelta shape and the setae B1, which measures two thirds of the tube length. We include a key based on characters of phylogenetic importance. Rev. Biol. Trop. 55 (2): 627-635. Epub 2007 Jun 29.

Este género se distingue por los estiletes maxilares muy apartados entre sí, carece de puente maxilar, la forma de la pelta y la seta B1 que es 2/3 la longitud del tubo. Se presenta el análisis crítico de este género y los posibles táxones emparentados, estableciendo un nuevo grupo a partir de las condiciones presentadas por Jironiella gen. n.

Cuscohoplininus pagoreni: a new genus and species of Hoplinini stilt bug from Peru (Heteroptera: Berytidae)

The Berytidae or stilt bugs are a cosmopolitan family of lygaeoid bugs, which are slender, elongate insects, with generally cylindrical bodies and very long, slender antennae and legs. Members of the tribe Hoplinini are characterized by the lack of a distinct metapleural scent channel and the possession of a dorsally directed process on the caudal edge of the male genitalia capsule (absent in Xenoloma and Cuscohoplininus). In this paper, we described the new genus and species Cuscohoplininus pagoreni from Peru. Scanning electron micrographs are provided to illustrate taxonomically important structures. Among the eight genera known in the tribe Hoplinini, the new genus Cuscohoplininus resembles Parajalysus in general aspect and size, but can be easily distinguished by the following characters: Parajalysus is characterized by the four large, erect pronotal spines, one centered on the anterior lobe, and on the posterior lobe, one at each humeral angle and one at the base of the meson; whereas, Cuscohoplininus has a single spine on the anterior pronotal lobe, an elongate scutellar spine (a tubercle is present in Parajalysus), and lacks a process on the caudal edge of the male genitalia capsule. Rev. Biol. Trop. 55 (2): 673-676. Epub 2007 June, 29.

La familia Berytidae es cosmopolita y está integrada por chinches alargadas, con cuerpo generalmente cilíndrico y con antenas y patas muy largas. Los miembros de la tribu Hoplinini se caracterizan por carecer de canal la glándula repugnatoria y por poseer un proceso caudal dirigido dorsalmente sobre el borde posterior de la cápsula genital masculina (ausente en Xenoloma y Cuscohoplininus). Describimos un nuevo género y especie: Cuscohoplininus pagoreni de Perú. Se tomaron fotografías de microscopia electrónica para ilustrar estructuras de importancia taxonómica. Entre los ocho géneros conocidos de la tribu Hoplinini, Cuscohoplininus n. gen. es similar al género Parajalysus en aspecto general y en tamaño. Sin embargo, puede distinguirse así: Parajalysus se caracteriza por poseer cuatro grandes espinas erectas sobre el pronoto, una en el centro del lóbulo anterior, una en cada ángulo humeral y, la cuarta, también sobre el lóbulo posterior sobre el margen posterior; por otro lado Cuscohoplininus tiene una sola espina sobre el pronoto situada sobre el lóbulo anterior, una espina escutelar (Parajalysus presenta solo un tubérculo sobre el escutelo) y carece de proceso caudal.

Los tisanópteros del grupo genérico Anaphothrips (Thysanoptera: Thripidae), con écnfasis en América Central / Thysanopterans of the generic group Anaphothrips (Thripidae: Thripinae) with emphasis in Central America

A taxonomic revision and phylogenetic analysis of the generic group Anaphothrips are presented. Several genera in Central America are closely related to this generic group. Based on the analysis of characters and its possible evolution, the new genus Nakaharathrips has been segregated from Anaphothrips, and the taxonomic status of the subspecies of Aurantothrips has been changed to the species level. The phylogenetic analysis shows a close relationship between the genera Anaphothrips, Ranjana, Nakaharathrips n.gen., Aurantothrips, Nicolemma n.gen., Ameranathrips, Baileyothrips and Gonzalezya n.gen., where the first lineage is formed by the genera (Ranjana (Aurantothrips+Nicolemma)) and the second lineage contains the genera [(Anaphothrips+Nakaharathrips)(Baileyothrips (Ameranathrips+Gonzalezya)].

Revision of the eastern Pacific species of Gobulus (Perciformes: Gobiidae), with description of a new species

Gobulus birdsongi is described as a new species from the Pacific coast of Panama. The two other known species of Gobulus from the eastern Pacific, Gobulus crescentalis and G. hancocki are redescribed. Gobulus birdsongi differs from other species in the genus in having more numerous second dorsal and anal rays. Gobulus hancocki differs from G. crescentalis in having a much smaller eye. The genus is distinctive in having reversed countershading, with the ventral surface of the body darker than the dorsal surface.

A new genus and new species of Sciaenidae from the Gulf of Panama (Perciformes: Sciaenidae)

Paranebris bauchotae, a new genus and species of sciaenid from the Gulf of Panama is described from three specimens (138-212 mm SL). It is distinguished from all other sciaenids by having granulated tooth plates on the jaws and the premaxillary tooth plates that are exposed laterally of the lower jaw when the mouth is closed. The new genus shares the following characters with the New World genus Nebris: a thick fleshy and cartilage gap present between premaxillary bones where the ascending processes form an A-frame arch; gas bladder with a pair of long U-shaped appendages; and a thick, oval-shaped sagitta with deeply grooved caudal section of the sulcus. Paranebris bauchotae is distinct from all Nebris species in having a firmer interorbital skin and scale cover (spongy to the touch in Nebris), a larger eye (6-7 vs. 8-12 times in head length) and large ctenoid scales (vs. small and cycloid in Nebris).

A new genus of Holothyrina: Neothyridae (Arachnida, Anactinotrichida) from the Manaus area, Amazonas state, Brazil

A new genus of Neothyridae, type species Diplothyrus schubarti sp. n., is described from the leaf litter of a primary forest in the Reserva Florestal Adolpho Ducke, Manaus, Amazonas, Brazil. The two pairs of lateral excretory orifices instead of a single one in the type genus Neothyrus of the family Neothyridae, are diagnostic. A protonymph of Neothyrus ana Lehtinen, 1981, is also described as the first known nymphal stage of this family.

Um novo gênero de Neothyridae, espécie tipo Diplothyrus schubarti sp.n., é descrito da liteira dc uma floresta primária na Reserva Florestal Adolpho Ducke, Manaus, Amazonas, Brasil. Os dois pares laterais dc orifícios excretores, em vez de um único, como no gênero tipo Neothyrus da família Neothyridae, são usados como característica. Uma protoniinfa de Neothyrus ana Lehtinen, 1981, também é descrita como o primeiro estágio ninfal conhecido desta família.

Miracetyma etimaruya gen. et sp. n. (COPEPODA, POECILOSTOMATOIDA, ERGASILIDAE) FROM FRESHWATER FISHES OF THE BRAZILIAN AMAZON

Miracetyma etimaruyagen. et sp. n. is proposed from the gills filaments of Curimata cyprinoides(Linnaeus, 1758), Potamorhina latior(Spix, 1829) and Psectrogaster essequibensis(Gunther, 1864). The species of the new genus is characterized by having a more complex latching antenna. The claw is greatly reduced and has a groove; the third segment has one or two grooves; the first, second and third segments have one or two cuticular extensions. The legs have pectinate setae and the first endopod is greatly modified, very long, and without setae. The first segment of the first endopod is large, strong and elongate and the second segment is subcylindrical, slender and elongate. These modifications imply in a loss of swimming capacity which is linked to secure fixation on the gill filament. As a result, the leg morphology has evolved other functions.

Miracetyma etimaruyagen. et sp. n. é proposto. Os espécimens foram coletados dos filamentos branquiais de Curimata cyprinoides(Linnaeus, 1758), Potamorhina latior(Spix, 1829) e Psectrogaster essequibensis(Gunther, 1864). A espécie deste gênero caracteriza-se por apresentar um sistema de encaixe das antenas mais complexo e eficiente. A garra é muito reduzida e possui uma ranhura; o terceiro segmento tem uma ou duas ranhuras; o primeiro, o segundo e o terceiro segmentos têm uma ou duas extenções cuticulares. As pernas apresentam setas pectinadas e o primeiro endopodito é extremamente modificado, muito longo e sem setas. O primeiro segmento do primeiro endopodito é largo, forte e alongado e o segundo segmento é subcilíndrico, fino e alongado. Estas modificações implicam na perda da capacidade natatòria a qual esta ligada a uma segura fixação no filamento branquial. Como resultado da morfologia, as pernas desenvolveram outras funções.

Digamacris n. gen. (Orthoptera, Acrididae, Melanoplinae) de la region atlantica meridional de Brasil / Digamacris n. gen. (Orthoptera, Acrididae, Melanoplinae) from the Atlantic Meridional region of Brazil

Digamacris, a new genus of the Dichroplini (Acrididae, Melanoplinae) is described for the species Pezotettix amoenus Stal, 1878 and Dichroplus fratemus Carl, 1916, both included at present in the genus Dichroplus. These species live in edges and clearings of the Atlantic Forest (Mata Atlantica) of Brazil. D. fratemus is found in the states of Minas Gerais, Espirito Santo and Rio de Janeiro east of the Bay of Guanabara. D. amoenus in the state of Rio de Janeiro W. of the Bay of Guanabara and in the coastal area of the state of São Paulo. The species are illustrated and redescribed. Both have two neatly different chromatic forms of females, while the males are uniform in coloration and closely correspond with one of the female forms.
