    The caddisfly genus Nectopsyche: new gemma group species from Costa Rica and the Neotropics (Trichoptera:Leptoceridae)
    (University of Chicago Press, 1995) Holzenthal, Ralph W.
    Generic-level diagnoses are provided for adult males, females, and larvae of the longhorned caddisfly genus Nectopsyche Miiller (Trichoptera:Leptoceridae). In addition, seven new Costa Rican species in the gemma species group are described and illustrated: N. exophthalma n. sp., N. monticola n. sp., N. onyx n. sp., N. ortizi n. sp., (also known from Argentina, Brazil, Guyana, Mexico, Panama, Peru, Surinam, and Venezuela), N. tapanti n. sp., N. tuanis n. sp., and N. utleyorum n. sp. The new species are compared with two previously described gemma group species also known from Costa Rica, N. argentata Flint and N. gemmoides Flint, and these, too, are diagnosed and illustrated.

    A new Ecuadorian species of the rare Neotropical caddisfly genus Amphoropsyche Holzenthal (Trichoptera, Leptoceridae)
    (Pensoft Publishers, 2016) Holzenthal, Ralph W.; Rios-Touma, Blanca
    A new species of the rare long-horned caddisfly genus Amphoropsyche Holzenthal is described from Ecuador, bringing the number of species known from the genus to 15. All species are very regional in their distributions and known only from very few specimens. The new species, Amphoropsyche real, is similar to a number of previously described species from Colombia (A. ayura, A. cauca, A. flinti, A. quebrada, and A. stellata) and Ecuador (A. napo and A. tandayapa). The males can be distinguished from the others by features of segment X of the male genitalia, especially the prominent midlateral and subapicodorsal spinelike setae. An updated taxonomic key to males of the genus is provided.

    A new species of Amphoropsyche (Trichoptera, Leptoceridae) from Ecuador, with a key to the species in the genus
    (Pensoft Publishers, 2011) Holzenthal, Ralph W.; Rázuri-Gonzales, Luis Ernesto
    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., A. woodruffi Flint & Sykora, A. refugia Holzenthal, and A. 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.

    Revision of the Neotropical species of the caddisfly genus Wormaldia McLachlan (Trichoptera: Philopotamidae)
    (Magnolia Press, 2015) Munoz-Quedada, Fernando J.; Holzenthal, Ralph W.
    Wormaldia McLachlan 1865 is the 2nd largest genus in the family Philopotamidae (Trichoptera) after Chimarra Stephens 1829 and is diverse and widely distributed, with ca. 175 extant species in all biogeographic regions except the Australasian. In this monograph, 14 previously described species are recognized for the Neotropical region: W. alicia Bueno-Soria, Santiago-Fragoso, & Barba-Alvarez 2005 [Mexico]; W. arizonensis (Ling 1938) [Mexico, USA]; W. cornuta Bueno-Soria & Holzenthal1986 [Mexico]; W. dampfi Ross & King 1956 [Mexico, Nicaragua]; W. dorsata Ross & King 1956 [Mexico]; W. endonima Ross & King 1956 [Mexico]; W. esperonis Ross & King 1956 [Mexico]; W. insignis (Martynov 1912) [Peru]; W. luma Bueno-Soria & Holzenthal 1986 [Mexico]; W. matagalpa Flint 1995 [Costa Rica, Guatemala, Nicaragua]; W. palma Flint 1991 [Colombia]; W. planae Ross & King 1956 [southwestern USA, Mexico, Caribbean, Central America, and northern South America]; W. prolixa Flint 1991[Colombia]; and W. tarasca Bueno-Soria & Holzenthal 1986 [Mexico]. Also, 36 additional Neotropical species are newly diagnosed, described, and illustrated: W. andrea [Ecuador]; W. anhelitus [Central America]; W. araujoi [Ecuador]; W. aymara [Bolivia]; W. barbai [Mexico]; W. bolivari [Venezuela]; W. boteroi [Colombia]; W. buenorum [Mexico]; W. calderonae [Mexico]; W. chrismark [Panama]; W. contrerasi [Panama]; W. dachiardiorum [Colombia]; W. eberhardi [Panama]; W. flinti [Bolivia, Panama]; W. francovilla [Panama]; W. fredycarol [Costa Rica, Panama]; W. gallardoi [Costa Rica, Panama]; W. gonzalezae [Venezuela]; W. hedamafera [Costa Rica, Nicaragua]; W. imberti [Costa Rica]; W. inca [Peru]; W. isela [Mexico]; W. juarox [Costa Rica]; W. lauglo [Panama]; W. machadorum [Costa Rica, Panama]; W. maesi [Nicaragua]; W. menchuae [Guatemala]; W. monsonorum [Costa Rica]; W. navarroae [Mexico]; W. paprockevi [Costa Rica]; W. saboriorum [Panama]; W. tocajoma [Costa Rica]; W. trondi [Costa Rica, Panama]; W. tupacamara [Bolivia]; W. zunigae [Colombia]; and W. zunigarceorum [Costa Rica, Panama]. In addition, the species W. arcopa Denning 1966 from Panama is considered a junior subjective synonym of W. planae. Furthermore, new distribution records for the Neotropical region for several species are given. Diagnoses, redescriptions, and illustrations of the male genitalia of the other 14 described Neotropical species in the genus are also presented. Illustrations of the forewing and hind wing of 19 species are also given. A structural terminology for male tergum X is proposed. Finally, a key for identification of males of all Neotropical species is provided.

    Systematics of the Neotropical caddisfly genus Notidobiella Schmid (Trichoptera, Sericostomatidae), with the description of 3 new species
    (Pensoft Publishers, 2010) Holzenthal, Ralph W.; Blahnik, Roger J.
    Three new species of Notidobiella Schmid (Insecta: Trichoptera) are described from South America: Notidobiella amazoniana sp. n. (Brazil), N. brasiliana sp. n. (Brazil), and N. ecuadorensis sp. n. (Ecuador). In addition, the 3 previously described species in the genus, N. chacayana Schmid, N. inermis Flint, and N. 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 signifi cant 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.

    Twenty-four new species of Polycentropus (Trichoptera, Polycentropodidae) from Brazil
    (Pensoft Publishers, 2011) Hamilton, Steven W.; Holzenthal, Ralph W.
    Twenty-four new species of the caddisfl y 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 Polycentropus sensu lato. Furthermore, 6 new species within the P. gertschi group (P. ancistrus sp. n., P. boraceia sp. n., P. carioca sp. n., P. froehlichi sp. n., P. galharada sp. n., and P. graciosa sp. n.) are placed in an informal diagnostic cluster of species with P. urubici Holzenthal & Almeida. Ten of the other P. gertschi group species form a second cluster of diagnostically similar species, the Polycentropus soniae cluster (P. caaete sp. n., P. carolae sp. n., P. cheliceratus sp. n., P. fl uminensis sp. n., P. itatiaia sp. n., P. minero sp. n., P. santateresae sp. n., P. soniae sp. n., P. tripui sp. n., and P. virginiae sp. n.). Two of the remaining 8 new species are included in the P. jorgenseni species complex (P. cipoensis sp. n. and P. verruculus sp. n.), while the remaining 6 are unique and cannot be placed in one of the groups at this time (P. acinaciformis sp. n., P. amphirhamphus sp. n., P. cachoeira sp. n., P. inusitatus sp. n., P. paprockii sp. n. and P. rosalysae sp. n.).
