    Phylogeny of the microcaddisflies with a revision of the genus Leucotrichia Mosely (Trichoptera: Hydroptilidae)
    (2014-04) Thomson, Robin Elizabeth
    Hydroptilidae Stephens, 1836 is the most diverse family [6 subfamilies, 76 genera (including 3 fossil genera), and over 2,100 species] belonging to the order Trichoptera. The family is cosmopolitan, occurring in all faunal regions of the world. A summary of the general morphology, biology, and taxonomic history and an overview of historically recognized taxa of Hydroptilidae are provided. Monophyly of Hydroptilidae and each of the 6 subfamilies was tested using 90 ingroup taxa, mitochondrial DNA (COI), and ribosomal RNA (D1-3). Maximum likelihood and Bayesian analysis methods were used to estimate phylogeny. Monophyly was recovered for Hydroptilidae, but not Ptilocolepidae. Monophyly was also recovered for the subfamilies Leucotrichiinae, Neotrichiinae, Ochrotrichiinae, and Stactobiinae. Monophyly for the subfamilies Hydroptilinae and Orthotrichiinae was not recovered. The genera Alisotrichia and Cerasmatrichia were recovered as a clade separate from all other subfamilies, as was the genus Byrsopteryx. The genus Dibusa, formerly incertae sedis, was recovered as sister to all other hydroptilids genera, excluding Palaeagapetus and Ptilocolepus. The genus Orphninotrichia, also formerly incertae sedis, was recovered within one clade of Hydroptilinae genera. Several taxonomic changes were necessary for classification to reflect phylogeny. Accordingly, I propose that the ptilocolepid genera Palaeagapaetus and Ptilocolepus be returned to Hydroptilidae as 2 genera separate from any subfamily. I also propose that the status of Alisotrichia, Byrsopteryx, and Cerasmatrichia be changed to incertae sedis within Hydroptilidae and that Dibusa and Orphninotrichia be removed from incertae sedis. A species-level revision of Leucotrichia was also completed, including a generic diagnosis, illustrations, a key, and descriptions of males. A total of 43 species were treated, 13 described as new: Leucotrichia angelinae, new species (Venezuela), L. denticulata, new species (Mexico), L. dianeae, new species (Costa Rica), L. fulminea, new species (Ecuador), L. hispida, new species (Costa Rica), L. kateae, new species (Venezuela), L. pectinata, new species (Ecuador), L. procera, new species (Brazil), L. repanda, new species (Venezuela), L. rhomba, new species (Costa Rica), L. riostoumae, new species (Ecuador), L. sidneyi, new species (Venezuela), and L. tapantia, new species (Costa Rica). Descriptions and new records for hydroptilid species found in Brazil and Venezuela were also provided. Illustrations and descriptions of males were given for all new species. A total of 10 new species were described: Acostatrichia digitata, new species (Venezuela), Betrichia alibrachia, new species (Brazil), Hydroptila cressae, new species (Venezuela), Leucotrichia bicornuta, new species (Brazil), Metrichia bostrychion, new species (Venezuela), Ochrotrichia spira, new species (Venezuela), Oxyethira bettyae, new species (Venezuela), Oxyethira quiramae, new species (Venezuela), Oxyethira redunca, new species (Venezuela), and Rhyacopsyche shorti, new species (Venezuela). New records were provided for 2 species: Neotrichia feolai Santos and Nessimian, 2009 (Venezuela) and Oxyethira picita Harris and Davenport, 1999 (Venezuela).

    A revision of the Neotropical caddisfly genus Rhyacopsyche, with the description of 13 new species (Trichoptera: Hydroptilidae)
    (Magnolia Press, 2007) Wasmund, Anne M.; Holzenthal, Ralph W.
    The Neotropical genus Rhyacopsyche Müller, 1879, was last reviewed in 1971 when 5 species were known. Since that time, the genus has gradually grown to 13 species: R. andina Flint, 1991 (Colombia, Peru, Venezuela), R. chichotla Bueno & Hamilton, 1986 (Mexico), R. duplicispina Flint, 1996 (Tobago), R. hagenii Müller, 1879b (Argentina, Brazil, Uruguay), R. jimena Flint, 1991 (Colombia), R. matthiasi Flint, 1991 (Colombia), R. mexicana (Flint, 1967) (Costa Rica, Guatemala, Mexico, Nicaragua), R. mutisi Mey & Joost, 1990 (Colombia), R. obliqua Flint, 1971 (Mexico), R. peruviana Flint, 1975 (Ecuador, Peru), R. torulosa Flint, 1971 (Costa Rica, Guatemala), R. turrialbae Flint, 1971 (Costa Rica), and R. yatay Angrisano, 1989 (Argentina). Thirteen new species are described and illustrated: R. benwa (Bolivia, Ecuador, Peru), R. bulbosa (Brazil), R. colei (Venezuela), R. colombiana (Colombia), R. colubrinosa (Ecuador, Peru), R. dikrosa (Brazil), R. flinti (Venezuela), R. hasta (Peru), R. intraspira (Peru), R. otarosa (Venezuela), R. patulosa (Brazil), R. rhamphisa (Colombia, Costa Rica), and R. tanylobosa. (Ecuador, Peru, Venezuela). The distribution of Rhyacopsyche is widened to include Bolivia and Nicaragua. Detailed illustrations are presented for all species as well as diagnoses, descriptions, and a taxonomic key. A species level phylogenetic analysis using PAUP* 4.0b 10 was performed. A heuristic search was conducted based on 20 morphological characters of the male genitalia, with species of Ochrotrichia and Metrichia used as outgroups. A strict consensus of 23 equally parsimonious trees is presented. The analysis revealed 3 characters supporting the monophyly of Rhyacopsyche. The monophyly of 1 of the 2 previously established species groups, the turrialbae group, is supported.

    The Trichoptera of Panama I. New records for caddisflies (Insecta: Trichoptera) from the Republic of Panama
    (Center for Systematic Entomology Inc., 2015) Armitage, Brian J.; Harris, Steven C.; Holzenthal, Ralph W.
    The Republic of Panama currently has 245 recorded species of Trichoptera distributed among 13 families. Herein we add 32 new country records for Panama, including one new family (Limnephilidae) and one new genus (Limnephilus). We also provide the first collection information for Oxyethira maya Denning for Panama. These results are part of an ongoing effort to characterize the caddisfly fauna of Panama, and to evaluate that country’s major cuencas (water basins).
