Twenty new species are described and illustrated: T. acanthus (Mexico), T. chirripo (Costa Rica), T. clauseni (Costa Rica, Nicaragua, Panama), T. cuyotenango (Guatemala), T. flintorum (Mexico), T. guadaloupe (Panama), T. hodgesi (Ecuador), T. hornitos (Panama), T. kilambe (Nicaragua), T. mexicanus (Mexico), T. moncho (Costa Rica), T. morai (Costa Rica, Nicaragua), T. nicaraguensis (Nicaragua), T. oaxacensis (Mexico), T. tajo (Costa Rica), T. talamanca (Costa Rica), T. tapanti (Costa Rica, Panama), T. tico (Costa Rica, Panama), T. tuxtlensis (Mexico), and T. woldai (Panama). In addition, 4 previously described species are redescribed and figured: T. abruptus Flint 1991 (Colombia), T. anomalus Flint 1967 (Nicaragua, Mexico), T. delicatus Navás 1924 (Costa Rica, Panama), and T. peruanus Flint & Reyes 1991 (Colombia, Ecuador, Peru). The status of Triaenodes columbicus Ulmer 1909, is discussed. The larval and pupal stages of a Costa Rican species and the females of 9 species are described, representing the first descriptions of these life history stages for Neotropical Triaenodes. The genus Ylodes Milne is returned to synonymy with Triaenodes, as a subgenus. A key to the males of Neotropical Triaenodes is provided.Item Catalog of the Neotropical Trichoptera (Caddisflies)(Pensoft Publishers, 2017) Holzenthal, Ralph W.; Calor, Adolfo R.The Neotropical caddisfly (Trichoptera) fauna is cataloged from a review of over 1,000 literature citations through 2015 (partial 2016) to include 3,262 currently recognized, valid species-group names in 25 families and 155 extant genera. Fourteen subspecies are included in the total as well as 35 fossil species and 1 fossil genus. The region covered includes all of Mexico, Central America, the Caribbean, and South America. Genus-group and species-group synonyms are listed. For each nominal species, information on the type locality, type depository, sex of type, distribution by country, and other pertinent taxonomic or biological information is included. Summary information on taxonomy, phylogeny, distribution, immature stages, and biology are provided for each family and genus where known. An extensive index to all nominal taxa is included to facilitate use of the catalog. The glossosomatid species Mexitrichia usseglioi Rueda Martín & Gibon, is transferred to Mortoniella comb. n.Item Checklist of the Trichoptera (Insecta) of Brazil I(2004) Paprocki, Henrique; Holzenthal, Ralph W.; Blahnik, Roger J.We present here a list of Trichoptera species recorded in the literature from Brazil as of September 2003. The total number of species recorded for Brazil is 378. The most diverse family is Hydropsychidae with 103 species; the second most diverse is Hydroptilidae with 50 species, followed by Leptoceridae and Philopotamidae with 41 each. Distributions by state and additional literature relevant to Brazilian Trichoptera are also presented.Item First data on Trichoptera fauna (Insecta) of streams and ponds of Vostok Bay Basin (Peter the Great Bay, Primorye Territory).(University of Chicago Press Jounrals, 2013) Vshivkova, T. S.; Flint, O. S.; Holzenthal, R. W.; Kjer, K. M.; Frandsen, P. B.; Thomson, R. E.; Egorov, A. B.Trichoptera fauna of streams and ponds of Vostok Bay Basin (Peter The Great Bay) was unknown up to now. Due to collections of the CRDF-FEBRAS 2011-2012 international expeditions an annotated list of caddisflies inhabiting this area was prepared. The list is included 56 species from 37 genera and 21 families. The data on biogeographical distribution of the species are given.Item Five new species of Polycentropodidae (Trichoptera) from Ecuador and Venezuela(Magnolia Press, 2005) Hamilton, Steven W.; Holzenthal, Ralph W.Diagnoses, descriptions and illustrations of male genitalia are given for four new species of the Polycentropus gertschi group, Polycentropus cressae n. sp., Polycentropus neblinensis n. sp., Polycentropus quadricuspidis n. sp., and Polycentropus silex n. sp. The former two are from Venezuela and the latter two from Ecuador. In addition, a diagnosis, description and set of male genitalia illustrations are provided for Polyplectropus beccus, a new species from Ecuador. The generic placement of this species, while currently appropriate, may require reclassification pending completion of ongoing studies on Neotropical polycentropodids.Item Four new species of Contulma from South America (Trichoptera: Anomalopsychidae)(Magnolia Press, 2006) Holzenthal, Ralph W.; Robertson, Desiree R.Four new species in the caddisfly genus Contulma Flint 1969 (Trichoptera: Anomalopsychidae) are described from Bolivia and southeastern Brazil: C. boliviensis n. sp. (Bolivia), C. fluminensis n. sp. (Brazil), C. meloi n. sp. (Brazil), and C. tripui n. sp. (Brazil). The Bolivian species represents the first record of the genus and family for Bolivia. The Brazilian species form a closely related group of species also including C. tijuca Holzenthal & Flint 1995.Item The genus Ochrotrichia Mosely (Trichoptera: Hydroptilidae) in Costa Rica, with the description of four new species(Magnolia Press, 2008) Bueno-Soria, Joaquin; Holzenthal, Ralph W.Four new species of the genus Ochrotrichia Mosely, are described from Costa Rica and the male genitalia figured (Ochrotrichia avicula new species, Ochrotrichia conformalis new species, Ochrotrichia jolandae new species, and Ochrotrichia quasi new species). Twenty-five species are recorded from Costa Rica, 8 for the first time [O. aldama (Mosely), O. arranca (Mosely), O. assita Bueno-Soria & Holzenthal, O. caimita Flint, O. glabra Bueno-Soria & Santiago-Fragoso, O. hondurenia Bueno-Soria & Santiago-Fragoso, O. panamensis Flint, and O. tagala Flint] and new distributional records are listed. Ochrotrichia arranca (Mosely) is refigured and compared with O. conformalis, new species and O. quasi, new species.Item Historical and contemporary biological diversity of Minnesota caddisflies: a case study of landscape-level species loss and trophic composition shift(University of Chicago Press, 2010) Houghton, David C.; Holzenthal, Ralph W.The biological diversity reflected by nearly 300,000 caddisfly specimens collected throughout Minnesota since 1985 was compared with that of 25,000 specimens recorded prior to 1950 and was analyzed based on the 5 caddisfly regions of Minnesota. In the Lake Superior, Northern, and Southeastern regions, .90% of species known historically from each region were recovered and additional species were discovered. In the Northwestern and Southern regions—the most disturbed areas of Minnesota—species recovery ranged from 60 to 70%. Historical and contemporary assemblages were similar to each other in the former 3 regions and markedly different in the latter 2. Prior to 1950, species in all trophic functional groups were widespread in all regions. A similar pattern still exists in the Lake Superior, Northern, and Southeastern regions, whereas the Northwestern and Southern regions are now dominated by filtering collectors in all sizes of lakes and streams. Over 65% of species extirpated from any region were in the long-lived families Limnephilidae and Phryganeidae, and 70% of these same species were in the shredder functional group. Almost 30% of the statewide fauna has been found from ,5 localities since 1950, suggesting a degree of imperilment on par with that of freshwater bivalves, gastropods, and fish. These observed losses of biodiversity and changes in trophic composition have probably occurred as a result of anthropogenic disturbance throughout most of the northcentral US.Item Nectopsyche Neotropical Trichoptera Newsletter, Issue Number 1(University of Minnesota Insect Collection, 2004-01-31) No authorItem Nectopsyche Neotropical Trichoptera Newsletter, Issue Number 1 Supplement(University of Minnesota Insect Collection, 2004-01-31) No authorItem Nectopsyche Neotropical Trichoptera Newsletter, Issue Number 2(University of Minnesota Insect Collection, 2004-09-08) No authorItem Nectopsyche Neotropical Trichoptera Newsletter, Issue Number 3(University of Minnesota Insect Collection, 2006-06) No authorItem The Neotropical caddisfly genus Canoptila (Trichoptera: Glossosomatidae)(Magnolia Press, 2006) Robertson, Desiree R.; Holzenthal, Ralph W.The caddisfly genus Canoptila Mosely (Glossosomatidae: Protoptilinae), endemic to southeastern Brazil, is diagnosed and discussed in the context of other protoptiline genera, and a brief summary of its taxonomic history is provided. A new species, Canoptila williami, is described and illustrated, including a female, the first known for the genus. Additionally, the type species, Canoptila bifida Mosely, is redescribed and illustrated. There are three possible synapomorphies supporting the monophyly of Canoptila: 1) the presence of long spine-like posterolateral processes on tergum X; 2) the highly membranous digitate parameres on the endotheca; and 3) the unique combination of both forewing and hind wing venational characters.Item The Neotropical caddisfly genus Tolhuaca (Trichoptera: Glossosomatidae)(Magnolia Press, 2005) Robertson, Desiree R.; Holzenthal, Ralph W.The caddisfly genus Tolhauca Schmid 1964 (Glossosomatidae: Protoptilinae) is diagnosed and discussed in the context of other protoptiline genera, and a review of its taxonomic history is provided. A new species, Tolhuaca brasiliensis, from southeastern Brazil, is described and illustrated, and the type species, Tolhuaca cupulifera Schmid 1964, from Chile, is redescribed and illustrated. Additionally, females of the genus are described and illustrated for the first time. Characters of the female genitalia, wing venation, and thorax suggest that Tolhuaca is more primitive than any other protoptiline genus and probably deserves a basal placement within the subfamily. The genus shows a broadly disjunct distribution perhaps reflecting an ancient southern Gondwana pattern.Item New distribution and species records of Trichoptera from Southern and Southeastern Brazil(2004) Blahnik, Roger J.; Paprocki, Henrique; Holzenthal, Ralph W.We provide here a list of new species records of Trichoptera (Insecta) collected in Southern and Southeastern Brazil. We report 21 new distribution records for the country of Brazil. We also provide new distribution records for 92 species of Trichoptera for the states of Minas Gerais, São Paulo, Rio de Janeiro, Paraná and Santa Catarina.Item A new Ecuadorian species of the rare Neotropical caddisfly genus Amphoropsyche Holzenthal (Trichoptera, Leptoceridae)(Pensoft Publishers, 2016) Holzenthal, Ralph W.; Rios-Touma, BlancaA 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.Item A new genus of long-horned caddisfly from the Amazon basin (Trichoptera: Leptoceridae: Grumichellini)(Magnolia Press, 2004) Holzenthal, Ralph W.; Pes, Ana Maria OliveiraAmazonatolica hamadae, new genus, new species (Leptoceridae: Grumichellini), is described from the Amazon basin of Brazil. The adult male and female, larva, pupa and case are described and illustrated. The biology and habitat of the new species is unusual for members of its tribe in that it occurs attached to vegetation in acidic, lowland streams.Item New micro-caddisflies from the Southeastern United States (Trichoptera: Hydroptilidae)(1983) Holzenthal, Ralph W.; Kelley, Robert W.Males of 6 new species of Hydroptilidae (Trichoptera) from the southeastern United States are described and illustrated: Hydroptila carolae n.sp. from South Carolina, H. disgalera n.sp. from Alabama and South Carolina, H. ouachita n.sp. from Louisiana, H. poirrieri n.sp. from Louisiana and Mississippi, H. trid
