    The caddisfly genus Triaenodes in Neotropics (Trichoptera: Leptoceridae)
    (Magnolia Press, 2004) Holzenthal, Ralph W.; Andersen, Trond
    The genus Triaenodes as it occurs in the Neotropics is diagnosed and discussed in the context of the world fauna. 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.

    Review of the caddisfly genus Tagalopsyche with the description of new species and a related new genus (Trichoptera: Leptoceridae: Mystacidini)
    (Magnolia Press, 2007) Holzenthal, Ralph W.; Andersen, Trond
    The long-horned caddisfly genus Tagalopsyche Banks, 1913 (Leptoceridae: Mystacidini) is reviewed and 4 new species are described and illustrated: T. apratita, new species (India), T. jolandae, new species (Brunei, Malaysia), T. kjaerandseni, new species (Ghana), and T. udagama, new species (India, Sri Lanka). The 4 previously described species are redescribed and illustrated: T. aethiopica Kimmins, 1963a (Ethiopia), T. brunnea (Ulmer, 1905) (Indonesia), T. fletcheri Kimmins, 1963b (India), and T. sisyroides Banks, 1913 (Indonesia, Philippines). A related new genus, Fernandoschmidia, new genus, and 2 new species, F. amudita, new species, and F. aramaniya, new species, from India are described and illustrated. The phylogenetic position of the new genus is assessed; it is sister to a clade formed by Tagalopsyche and Mystacides Berthold, 1827, the only other genus in the Mystacidini.

    West African Triaenodes McLachlan (Trichoptera: Leptoceridae). 1. Introduction and subgenus Triaenodella Mosely
    (Brill Academic Publishers, 2001) Andersen, Trond; Holzenthal, Ralph W.
    Two new Triaenodes McLachlan species belonging to subgenus Triaenodella Mosely, T. akosua sp. n. and T. amma sp. n., are described and figured, and four previously described species, T. dolobratus Gibbs, T. ghana Kimmins, T. proszynskii (Marlier & Botosaneanu), and T. serratus Ulmer are redescribed and figured based on males collected in Ghana. The female of T. proszynskii as well as the female holotype of T. palpalis Banks from Cameroon are also redescribed and figured. Further, an additional new species, T. kwadwo sp. n., from Ghana is described and figured; this species does not readily fit into any subgenus. A key to the subgenera of West African Triaenodes males and a key to the males of subgenus Triaenodella are provided.

    (Brill Academic Publishers, 2002) Andersen, Trond; Holzenthal, Ralph W.
    Seven new Triaenodes McLachlan species belonging to subgenus Triaenodes sensu stricto, T. akua sp. n., T. kofi sp. n., T. kwabena sp. n., T. kwaku sp. n., T. kwame sp. n., T. kwasi sp. n., and T. yaw sp. n., are described and figured based on males collected in Ghana. Adult males of the seven previously described species recorded from West Africa, T. africanus Ulmer, T. darfuricus Mosely, T. elegantulus Ulmer, T. imakus Gibbs, T. scottae Gibon, T. tofanus Gibbs, and T. troubati Gibon are redescribed and figured. A key to the males of the West African species of Triaenodes sensu stricto is provided.
