Twenty-four new species of Polycentropus (Trichoptera, Polycentropodidae) from Brazil

Twenty-four new species of the caddisfly genus Polycentropus (Insecta: Trichoptera: Polycentropodidae) occurring in Brazil are diagnosed, described, and the male genitalia of each are illustrated. Eighteen of the new species are placed in the Polycentropus jorgenseni species complex of the Polycentropus gertschi group of New World Polycentropussensu lato. Furthermore, 6 new species within the Polycentropus gertschi group (Polycentropus ancistrussp. n., Polycentropus boraceiasp. n., Polycentropus cariocasp. n., Polycentropus froehlichisp. n., Polycentropus galharadasp. n., and Polycentropus graciosasp. n.) are placed in an informal diagnostic cluster of species with Polycentropus urubici Holzenthal and Almeida. Ten of the other Polycentropus gertschi group species form a second cluster of diagnostically similar species, the Polycentropus soniae cluster (Polycentropus caaetesp. n., Polycentropus carolaesp. n., Polycentropus cheliceratussp. n., Polycentropus fluminensissp. n., Polycentropus itatiaiasp. n., Polycentropus minerosp. n., Polycentropus santateresaesp. n., Polycentropus soniaesp. n., Polycentropus tripuisp. n., and Polycentropus virginiaesp. n.). Two of the remaining 8 new species are included in the Polycentropus jorgenseni species complex (Polycentropus cipoensissp. n. and Polycentropus verruculussp. n.), while the remaining 6 are unique and cannot be placed in one of the groups at this time (Polycentropus acinaciformissp. n., Polycentropus amphirhamphussp. n., Polycentropus cachoeirasp. n., Polycentropus inusitatussp. n., Polycentropus paprockiisp. n. and Polycentropus rosalysaesp. n.).

First report of the genus Kisaura Ross (Trichoptera, Philopotamidae) from India with the description of six new species

The genus Kisaura Ross, 1956 (Trichoptera, Philopotamidae, Philopotaminae) is reported from India the first time. Six new species are described and illustrated: Kisaura elongatasp. n., Kisaura eloctsp. n., Kisaura clavatasp. n., Kisaura gangtokensissp. n., Kisaura truncatasp. n., all from Gangtok (Sikkim) and Kisaura himachalicasp. n. from Barot (Himachal Pradesh). Male genitalia of this genus are distinguishable from those of other genera of the family by the pair of long lateral processes of tergum X, the well-developed mesoventral plates between two segments of the inferior appendages, and by the brush-like row of dark setae on the inner surfaces of the terminal segments (harpago) of the inferior appendages.

A new species of Amphoropsyche (Trichoptera, Leptoceridae) from Ecuador, with a key to the species in the genus

A new species of Amphoropsyche Holzenthal is described from Ecuador. It is similar to a group of species with dorsomesal processes on the preanal appendages (i.e., Amphoropsyche woodruffi Flint & Sykora, Amphoropsyche refugia Holzenthal, and Amphoropsyche aragua Holzenthal), but can be distinguished from these and other members of the genus by the short, digitate dorsomesal processes on the preanal appendages and the broad lateral processes of tergum X of the male genitalia. A key to males of the 14 species now known in the genus is presented based on characters of the genitalia.     

Three new species of Atopsyche Banks (Trichoptera, Hydrobiosidae) from Brazil

Three new species of Atopsyche Banks (Hydrobiosidae) from Brazil are described and illustrated: Atopscyhe (Atopsaura) blahniki sp. n., Atopsyche (Atopsyche) parauna sp. n., and Atopsyche (Atopsaura) galharada sp. n. Additional illustrations of the male genitalia of Atopsyche urumarca Schmid are provided, including its populational variation. Also, we provide new state records for 2 species: Atopsyche (Atopsyche) urumarca from São Paulo, and Atopsyche (Atopsaura) plancki Marlier from Santa Catarina.     

Systematics of the Neotropical caddisfly genus Notidobiella Schmid (Trichoptera, Sericostomatidae), with the description of 3 new species

Three new species of Notidobiella Schmid (Insecta: Trichoptera) are described from South America: Notidobiella amazonianasp. n. (Brazil), Notidobiella brasilianasp. n. (Brazil), and Notidobiella ecuadorensissp. n. (Ecuador). In addition, the 3 previously described species in the genus, Notidobiella chacayana Schmid, Notidobiella inermis Flint, and Notidobiella parallelipipeda Schmid, all endemic to southern Chile, are redescribed and illustrated, including the females of each species for the first time, and a key to males of the species in the genus is provided. The occurrence of Notidobiella in Brazil and Ecuador represents a significant extension of the range of the genus beyond southern Chile where it previously was thought to be endemic. The biogeography of Sericostomatidae and other austral South American Trichoptera is reviewed. The presence of the family in South America may not be part of a "transantarctic" exchange, but instead may represent an earlier occurence in the region. The distribution of Notidobiella in tropical South America likely represents recent dispersal from southern South America to the north.     

Comparison of sensory structures on the antenna of different species of Philopotamidae (Insecta: Trichoptera)

Structure and distribution of sensilla were studied in sixteen species of the caddisfly family Philopotamidae. Their antennae bear numerous curved trichoid and pseudoplacoid sensilla and fewer coronal, styloconic and chaetoid sensilla on the flagellar segments. The most numerous pseudoplacoid sensilla have non-specific localization. The curved trichoid sensilla form clusters ventrally on each antennal segment. Sensilla belonging to coronal, styloconic and chaetoid types have specific positions. Long grooved trichoid sensilla are located nonspecifically in all the studied species. The average number of sensilla per segment decreases from the proximal to distal part of the flagellum. Scapus and pedicellum are devoid of most types of sensilla, however, they bear the Böhm bristles and long trichoid sensilla. A positive correlation between antenna dimensions and its cuticular structures is found.     

A new species of the genus Molanna Curtis (Trichoptera, Molannidae) from the Yaeyama Islands, the southernmost part of Japan

Systematics of Otarrha, a new Neotropical subgenus of Chimarra (Trichoptera: Philopotamidae)

Abstract. Subgenus Otarrha is established in genus Chimarra to include eighteen described species formerly placed either in subgenus Chimarra or unplaced to subgenus, and thirteen new species. All species are Neotropical, with collective distributions primarily in the Antilles (Greater and Lesser) and northern South America. One species occurs in southeastern Brazil and another species in Costa Rica and Panama. New species are described, recognized species redescribed (except for C. diannae and C. koki ), and a key to the identification of males in the subgenus is provided. Additionally, characters supporting monophyly of the subgenus and a phylogeny of its species are proposed. Described species transferred to this subgenus include Chimarra cubanorum Botosaneanu, C . diakis Flint, C . diannae Flint & Sykora, C . dominicana Flint, C . garciai Botosaneanu, C . guapa Botosaneanu, C . jamaicensis Flint, C . koki Botosaneanu, C . machaerophora Flint, C . patosa Ross, C . puertoricensis Flint, C . quadrifurcata Botosaneanu, C . retrorsa Flint, C . rossi Bueno-Soria, C . sensillata Flint, C . septemlobata Flint, C . septifera Flint and C . spinulifera Flint. Chimarra patosa is designated the type species of the subgenus. New species described in Otarrha include Chimarra amazonia (Peru), C . barinas (Venezuela), C . darlingtoni (Cuba), C . diaphora (Venezuela), C . incipiens (Venezuela), C . odonta (Brazil), C . parene (Peru), C . parilis (Peru), C . particeps (Peru), C . peruana (Peru), C . phthanorossi (Colombia), C . redonda (Dominican Republic) and C . tachuela (Venezuela). Two additional species are described and left incertae sedis to subgenus, Chimarra usitatissima Flint and C . angularis , sp.n. (Venezuela, Guyana).     

Two new species of caddisflies from East Asia （Trichoptera： Philopotamidae, Psychomyiidae）

A new species of Kisaura Ross （Philopotamidae） from Japan and a new species of Psychomyia Latreille （Psychomyiidae） from Russia are described. Kisaura imparis n. sp. is closest to Kisaura aurascens （Martynov, 1934）, but the lateral processes of tergum X are asymmetrical and the apex of tergum X is different. Psychomyia poltavkaensis n. sp. resembles Psychomyia n. sp., but the shape of tergum IX＋X is more rounded, the apex of the basoventral process of each preanal appendage is unforked, and the inferior appendages are branched.     

A New Neotropical Genus and Species of Odontocerinae (Trichoptera: Odontoceridae) from Southeastern Brazil

Anastomoneura gen. nov. and A. guahybae sp. nov. are described and illustrated based on adult male and female specimens from the Mantiqueira mountain range, Minas Gerais State. This is the third genus recorded of the family Odontoceridae from South America. The new genus is characterized by the forewing anastomosis of veins R₄ and R₅ and male genitalia with a unique, tubular, projection dorsad to the plates of tergite X.     

A review of Rheocricotopus (Psilocricotopus) chalybeatus species group from China,with the description of three new species (Diptera,Chironomidae)

The Rheocricotopus (Psilocricotopus) chalybeatus species group from China is reviewed. Three new species, R. (P.) brochus sp. n., R. (P.) rotundus sp. n. and R. (P.) serratus sp. n. are described as adult males. R. (P.) imperfectus Makarchenko & Makarchenko, 2005, R. (P.) robacki (Beck & Beck, 1964) and R. (P.) valgus Chaudhuri & Sinharay, 1983 are recorded from China for the first time and annotated. The diagnosis for the species group is emended and a key to adult males of the species group in China is presented.     

New species, nomenclatural changes and lectotypifications in Neotropical Lepidagathis Willd. (Acanthaceae)

Summary  Taxonomic and phylogenetic studies of the Neotropical genus Lophostachys showed that it is congeneric with Lepidagathis. The following new combinations of species previously described under Lophostachys are proposed: Lepidagathis chiapensis (Acosta) Kameyama, L. cyanea (Leonard) Kameyama, L. guatemalensis (Donn. Sm.) Kameyama, L. laxifolia (Nees) Kameyama, L. montana (Nees) Kameyama, L. nemoralis (Mart. ex Nees) Kameyama, L. soconuscana (T. F. Daniel) Kameyama, and L. uxpanapensis (Acosta) Kameyama. Five new species are described: Lepidagathis callistachys, L. cuneiformis, L. meridionalis, L. paraensis and L. wasshausenii. Three lectotypes are also designated. A key to the Neotropical secundiflorous species is provided.     

Generic placement of the Neotropical species of " Phragmatobia" (Erebidae, Arctiinae), with a remarkable matrivorous species from the Peruvian Andes

Phragmatobia Stephens is briefly reviewed and a diagnosis is provided. The South American species currently placed in Phragmatobia Stephens are revised to two new genera, Andesobia Schmidt and De Freina, gen. n., and Patagobia Schmidt and De Freina, gen. n. (subtribe Spilosomina). Both Andesobia and Patagobia exhibit adaptations to high altitude habitats, including micropterous females in Andesobia (Patagobia females are unknown) and diurnal flight of males. The adults, immature stages, and mating behaviour of Andesobia jelskii (Oberthür, 1881) are described. Males of Andesobia jelskii enter the female cocoon to mate, and the micropterous, flightless females remain in the cocoon following oviposition where newly hatched larvae feed initially on the female’s body.Four species are included in Andesobia, Andesobia jelskii comb. n. (= Paracles imitatrix Rothschild, 1922, syn. n.), Andesobia flavata (Hampson, 1901), comb. n., Andesobia boliviana (Gaede, 1923), comb. n. (=Turuptiana flavescens Rothschild, 1933, syn. n.), and Andesobia sanguinea (Hampson, 1907), comb. n. Patagobia includes only Patagobia thursbyi (Rothschild, 1910), comb. n., and Patagobia thursbyi pluto Toulgoët is relegated to its synonymy. Patagobia shows affinities to Phaos Walker, 1855 of Australia, Metacrias Meyrick, 1886 of New Zealand, and Pseudophragmatobia Krüger, 2009 of South Africa, suggesting a common ancestry of circumantarctic origin. Phragmatobia karsholti Toulgoët, 1991 is transferred to Venedictoffia Toulgoët, comb. n., an unrelated genus that is removed from subtribe Arctiina and provisionally placed in the Phaegopterina. Phragmatobia oberthueri Rothschild, 1910, described from Tibet, is a synonym of Lachana alpherakii (Grum-Grzhimailo, 1891) [Erebidae: Lymantriinae], syn. n., comb. n.
