The genus Episcepsis Butler, 1877 is widely distributed in the Neotropical region and currently includes 43 valid species many of them described solely based on external morphology. The existence of species complexes makes their identification difficult without examination of genital morphology. Four new species from Brazil, Cuba and Peru are described herein; Episcepsis andina sp. nov., E. diversa sp. nov., E. insularis sp. nov. and E. travassosi sp. nov. Comparisons with other similar species as well as photographs of external morphology and male genitalia are provided.

Five new species of the genus Colobostema Enderlein, 1926 from Mexico are described and illustrated: C. emilianoi (Chiapas), C. marielae (San Luis Potosi), C. valentinae (Jalisco), C. lupitae (Oaxaca) and C. marlettae (Yucatan). A key to the males of Neotropical species of Colobostema is provided. The male genitalia structures (especially the vestiture of parameres and the shape of tergite 9) indicates that all these new species form a group of closely related taxa, associated to the species of the Nearctic and Neotropical region.

Similar Location

The “Lozopera” species group of the genus Aethes Billberg, 1820 comprises at least 26 described valid species distributed in the Palaearctic region. Most of them share similar external morphology and are identified mainly after their genitalia. The genitalia morphology of both sexes is comparatively complex and the taxa of the group are surrounded by numerous taxonomical problems. A thorough study of the genital morphology, aiming to solve some of the problems, revealed the existence of a microscopic seta on the vesica of the male phallus. SEM and light microscopy observations suggest that it is sensillum chaeticum and probably has a (mechano) receptive function. It is present in some species and absent in others, but always located near the gonopore. In some species a large acantha with similar location was found, instead. Apart from the “Lozopera” species group, such a sensillum was observed in other Aethes spp. and in other genera of the tribe Cochylini as well. Such a structure has never been reported on the vesica of a moth.

Neotropical Species

The identity of many Neotropical species of Pseudisobrachium Kieffer, 1904 is currently unreachable, mostly because the available descriptions and illustrations are not sufficiently accurate to allow precise identifications. To help solve the problem, 115 valid species and their junior synonyms were examined. Twelve nomenclatural acts are made, and 110 valid species are recognized for the Neotropical region. Two lectotypes are designated: Pristocera crassicornis Westwood and Pristocera haemorrhoidalis Westwood. Seven new species-group synonyms are proposed: Pseudisobrachium retusum Evans syn. nov. for P. pauxillum Evans; P. cunco Perez syn. nov. for P. erythrocephalum Evans; P. navajo Evans, P. rectangulatum Evans, P. emarginatum Evans and P. foutsi Evans syn. nov. for P. flavinervis Fouts; P. acuminatum Waichert & Azevedo syn. nov. for P. latum Waichert & Azevedo. The following new genus-group synonym is established: Parisobrachium Kieffer syn. nov. for Dissomphalus Ashmead. The following new combination and reinstated name are proposed: Dissomphalus albipes (Kieffer) comb. nov. and nom. rev. from Pseudisobrachium paraguayense Kieffer.

Number Of Segments

Ergasilus von Nordmann, 1832 is the type and the most speciose genus of Ergasilidae, with more than 150 valid species. The first species of this genus, Ergasilusiheringi Tidd, 1942, was described from the Neotropical Region, from the gills of Hopliasmalabaricus (Bloch, 1794). Since then, 35 new species of Ergasilidae have been described from the Neotropics. However, a reanalysis of the available type specimens of E.iheringi revealed features that suggest that it represents a lineage independent from Ergasilus. Consequently, we propose Tiddergasilus gen. nov. (Ergasilidae: Cyclopoida) to accommodate T.iheringi (Tidd, 1942) comb. nov. The species was re-examined and redescribed based on available type specimens. Tiddergasilus gen. nov. is characterized by species with exopod of leg 4 2-segmented; antenna small and robust, with a short second segment (approximately three times shorter than the first segment), and claw with a unique morphology (short, recurved with a sub-proximal indentation in the inner margin). A phylogenetic analysis, based on a matrix of 15 taxa and 16 morphological characters in PAUP* software 4.0a152, resulted in 15 equally parsimonious trees. Based on this analysis, Tiddergasilus is closely related to a group composed of Neotropical species of Ergasilus – sharing with them antennule with 6-segments. When the highly homoplastic character “number of segments in the antennule” is removed from the analysis, Tiddergasilus forms a polytomy with the clade of genera of the former Vaigamidae, Ergasilus, and the clade Rhinergasilus+Brasergasilus+Pindapixara.

The described Neotropical species of the common and speciose fairyfly genus Gonatocerus Nees ab Esenbeck (Hymenoptera: Mymaridae) are reviewed and re-diagnosed. Eighty-four valid species are recognized including 11 newly described ones. Illustrated identification keys are provided to identify the 5 subgenera recognized in Gonatocerus and to females of each subgenus. The keys include 79 of the treated species, the other five species are known from males only. The known distribution ranges of the species, including new records of extralimital specimens examined, are given. Host associations of the treated species are also given, with emphasis on those species that parasitize eggs of proconiine sharpshooters (Hemiptera: Cicadellidae: Cicadellinae: Proconiini), all of which belong to the ater and morrilli subgroups of the ater species group of G. (Cosmocomoidea Howard), stat. rev. The other four recognized subgenera within Gonatocerus are the nominate subgenus, G. (Gonatocerus) (= sulphuripes species group of authors), G. (Lymaenon Walker), stat. rev. (= litoralis and straeleni species groups of authors), G. (Gastrogonatocerus Ogloblin), stat. rev. (= membraciphagus species group of authors), and G. (Gahanopsis Ogloblin), syn. n. & stat. n. (= deficiens species group of authors). Newly treated as synonyms of G. (Lymaenon) are Rachistus Foerster, Oophilus Enock, Agonatocerus Girault, Gonatoceroides Girault, and Decarthrius Debauche, all syn. n. Two species groups are recognized within G. (Cosmocomoidea) in the New World: the ater group, to which most Neotropical species belong (with the ater, bucculentus, morrilli, and the newly defined chusqueicolus subgroups) and the masneri group, with two described species from the Dominican Republic. The 11 new species described are G. (Gahanopsis) arkadak Triapitsyn sp. n. (Colombia), G. (Cosmocomoidea) barbos Triapitsyn sp. n. (Costa Rica and Mexico), G. (Cosmocomoidea) blefuscu Triapitsyn sp. n. (Costa Rica), G. (Cosmocomoidea) cuscus Triapitsyn sp. n. (Peru), G. (Cosmocomoidea) garchamp Triapitsyn sp. n. (Argentina), G. (Cos- mocomoidea) gerasim Triapitsyn sp. n. (Mexico), G. (Cosmocomoidea) hispaniolus Triapitsyn & Huber sp. n. (Dominican Republic), G. (Cosmocomoidea) kiskis Triapitsyn sp. n. (Argentina), G. (Cosmocomoidea) logarzoi Triapitsyn sp. n. (Argentina), G. (Cosmocomoidea) mumu Triapitsyn sp. n. (Argentina), and G. (Cosmocomoidea) rakitovi Triapitsyn sp. n. (Costa Rica). Seven new synonymies are proposed: Gonatocerus h-luteum (Ogloblin) syn. n. under G. (Cosmoco- moidea) nigriflagellum (Girault); G. enicmophilus Huber syn. n. and G. necator (Ogloblin) syn. n. under G. (Cosmoco- moidea) bonariensis (Brèthes); G. dimorphus (Ogloblin) syn. n. and G. monrosi (Ogloblin) syn. n. under G. (Gastrogonatocerus) margiscutum Girault; and G. setulosus (Ogloblin) syn. n. and G. dorsiniger (Ogloblin) syn. n. under G. (Gastrogonatocerus) membraciphagus Ogloblin. Litus maculipennis Ashmead, Gahanopsis deficiens (Ogloblin), and Gahanopsis straeleni (Debauche) are transferred to Gonatocerus as, respectively, G. (Cosmocomoidea) maculipennis (Ashmead) comb. n., G. (Gahanopsis) deficiens (Ogloblin) comb. n., and G. (Lymaenon) straeleni (Debauche) comb. n. Lectotypes are designated for the following 23 species: G. (Gahanopsis) acanophorae (Ogloblin), G. (Gahanopsis) aethalionis (Ogloblin), G. (Cosmocomoidea) annulicornis (Ogloblin), G. (Gastrogonatocerus) anomocerus Crawford, G. (Gonatocerus) appendiculatus (Ogloblin), G. (Gonatocerus) bonaerensis (Ogloblin), G. (Cosmocomoidea) caudatus (Ogloblin), G.

A New Species

A new, and only the third known species of the Neotropical montane genus Oressinoma Doubleday is described—O. sorina n. sp., from the Andes of central Peru. It is distinguishable immediately from the other two congeners by the shape of the hindwing underside submarginal orange band, and by the male genitalia. The systematics of Oressinoma are reviewed. A preliminary analysis is carried out based on COI barcode confirming the separate specific status of O. sorina n. sp. in relation to other two congeners. Both barcode and genital morphology data suggest that the widespread O. typhla Doubleday may be a complex of allopatric or, locally parapatric species. The genus Oressinoma is the only neotropical member of the predominantly Australian subtribe Coenonymphina, represented in the entire Holarctic by one genus only—Coenonympha Hübner, considered as the putative sister-genus of Oressinoma. Their origins and relationships are briefly discussed.
