    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.

    Contulma paluguillensis (Trichoptera:Anomalopsychidae), a new caddisfly from the high Andes of Ecuador, and its natural history
    (University of Chicago Press, 2012) Holzenthal, Ralph W.; Rios-Touma, Blanca
    Adults and larvae of a new species of Contulma Flint (Trichoptera:Anomalopsychidae) are described from Ecuador. The new species is similar to Contulma papallacta Holzenthal and Flint, but differs in having shorter, less spatulate dorsolateral processes and shorter setose lateral processes of segment IX in the male genitalia. Monthly Hess, sticky trap, and emergence-trap collections indicated that the new species is uncommon, probably univoltine, but with continuous larval growth and extended adult emergence, and has algivorous larvae.

    A new species of Smicridea McLachlan (Trichoptera:Hydropsychidae) from Venezuela and its role in travertine biogenesis
    (The North American Benthological Society, 2003) Paprocki, Henrique; Holzenthal, Ralph W.
    We collected an undescribed hydropsychid caddisfly, Smicridea (Smicridea) travertinera, n. sp., from 2 sites in Venezuela. One of the sites, Quebrada El Charo, flowed over extensive calcareous formations of travertine, which were covered with retreats and capture nets of the new species. Smicridea travertinera was the most abundant aquatic insect colonizing travertine.We describe the adult male, the retreat and net, and gut contents. The retreat consisted of an aperture in the travertine with a capture net. Retreat-making behavior appears to cause both the biogenesis and erosion of the travertine formations.

    Order Trichoptera Kirby, 1813 (Insecta), Caddisflies
    (Magnolia Press, 2007) Holzenthal, Ralph W.; Blahnik, Roger J.; Prather, Aysha L.; Kjer, Karl M.
    The taxonomy, diversity, and distribution of the aquatic insect order Trichoptera, caddisflies, are reviewed. The order is among the most important and diverse of all aquatic taxa. Larvae are vital participants in aquatic food webs and their presence and relative abundance are used in the biological assessment and monitoring of water quality. The species described by Linnaeus are listed. The morphology of all life history stages (adults, larvae, and pupae) is diagnosed and major features of the anatomy are illustrated. Major components of life history and biology are summarized. A discussion of phylogenetic studies within the order is presented, including higher classification of the suborders and superfamilies, based on recent literature. Synopses of each of 45 families are presented, including the taxonomic history of the family, a list of all known genera in each family, their general distribution and relative species diversity, and a short overview of family-level biological features. The order contains 600 genera, and approximately 13,000 species.

    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.

    Revision and phylogeny of the caddisfly subfamily Protoptilinae (Trichoptera: Glossosomatidae) inferred from adult morphology and mitochondrial DNA
    (Magnolia Press, 2013) Robertson, Desiree R.; Holzenthal, Ralph W.
    Protoptilinae Ross, 1956, is the most diverse subfamily belonging to the saddle- or tortoise-case-making caddisfly family Glossosomatidae Wallengren, 1891. The subfamily has a disjunct distribution: 5 genera are known from the East Palaearctic and Oriental regions; the remaining 13 are restricted to the Nearctic and Neotropical regions. Monophyly of Protoptilinae and each of 17 genera was tested using 80 taxa, 99 morphological characters, and mitochondrial DNA (COI). Additionally, homologies of morphological characters were assessed across genera and a standardized terminology for those structures was established. Mitochondrial DNA data were unavailable for 55 of the 80 taxa included in this study. To test the effects of the missing molecular data, 5 different datasets were analyzed using both parsimony and Bayesian methods. There was incongruence between the COI and morphological data, but results suggest the inclusion of COI data in a combined analysis, although incomplete, improved the overall phylogenetic signal. Bayesian and parsimony analyses of all 5 datasets strongly supported the monophyly of Protoptilinae. Monophyly of the following genera was also supported: Canoptila Mosely, 1939; Culoptila Mosely, 1954; Itauara Müller, 1888; Mastigoptila Flint, 1967; Mortoniella Ulmer, 1906; Protoptila Banks, 1904; and Tolhuaca Schmid, 1964. Several taxonomic changes were necessary for classification to reflect phylogeny accurately. Accordingly, Matrioptila Ross, 1938; Poeciloptila Schmid, 1991; Temburongpsyche Malicky, 1992; and Nepaloptila Kimmins, 1964, are designated new junior synonyms of Padunia Martynov, 1910. Additionally, the endemic Caribbean genera Campsiophora Flint, 1964, and Cubanoptila Sykora, 1973, are designated new junior synonyms of Cariboptila Flint, 1964. Diagnoses and a key to the subfamilies of Glossosomatidae and world genera of Protoptilinae incorporating these taxonomic changes are provided.

    Revision of the Neotropical caddisfly genus Itauara Müller, 1888 (Trichoptera, Glossosomatidae)
    (Pensoft Publishers, 2011) Robertson, Desiree R.; Holzenthal, Ralph W.
    Systematics of the genus Itauara Müller, 1888 are reviewed. A generic diagnosis, illustrations, and descriptions are provided for males. The genus can be identified by several features of the male genitalia including an extremely reduced phallobase and a phallic apparatus that consists of a sclerotized dorsal sheath covering a very membranous ventral portion. A total 18 species are described as new: Itauara alexanderi, sp. n. (Brazil), I. bidentata, sp. n. (Guyana), I. blahniki, sp. n. (Brazil), I. charlotta, sp. n. (Brazil), I. emilia, sp. n. (Brazil), I. flinti, sp. n. (Brazil), I. guyanensis, sp. n. (Guyana), I. jamesii, sp. n. (Brazil), I. julia, sp. n. (Brazil), I. lucinda, sp. n. (Brazil), I. ovis, sp. n. (Guyana, Venezuela), I. peruensis, sp. n. (Peru), I. rodmani, sp. n. (Brazil), I. simplex, sp. n. (Brazil), I. spiralis, sp. n. (Guyana), I. stella, sp. n. (Brazil), I. tusci, sp n. (Brazil), and I. unidentata, sp. n. (Guyana). These additions bring the total fauna of Itauara to 22 species.

    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.

    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.

    Taxonomy and systematics: contributions to benthology and J-NABS
    (University of Chicago Press, 2010) Holzenthal, Ralph W.; Robertson, Desiree R.; Pauls, Steffen U.; Mendez, Patina K.
    Systematics, or taxonomy, is the study of the diversity of life on Earth. Its goals are to discover and describe new biological diversity and to understand its evolutionary and biogeographic origins and relationships. Here we review the contributions to the field of systematics and taxonomy published over the last 25 y in J-NABS and its predecessor Freshwater Invertebrate Biology (FIB). We examined a total of 64 studies that we considered to be largely taxonomic in nature. We classified these studies into 2 major categories: morphological (e.g., descriptive taxonomy, taxonomic revisions) and molecular (e.g., deoxyribonucleic acid [DNA] barcoding, population genetics). We examined studies in 5-y increments for J-NABS. We also studied the period 1982 to 1985, during which FIB was published. On average, 12 taxonomic studies were published within each 5-y period. Molecular studies first appeared in 1986 and have slowly increased, reaching their greatest number within the last 5 y. Studies also were classified by their individual attributes. Morphological studies were, by far, the most common, but studies also included molecular data, biological information, distributional data, keys, and biogeographical analyses. Most studies included .1 of these attributes. Overall, the role of J-NABS in the development of benthic taxonomy has been minimal in terms of number of publications, but as part of the nexus of taxomonic literature, all contributions have been important to the discipline. We discuss these contributions and their impact on the following subject areas: taxonomy and revisionary systematics, phylogenetic and molecular systematics, taxonomic resources, taxonomic resolution, conservation and taxonomy, professional training, taxonomic certification, and graduate education. We also give an overview of new developments in the taxonomists’ toolbox. These developments include DNA barcoding, online taxonomic resources, digital identification keys, cybertaxonomy, and modern museum collections and resources.

    Three new species of Helicopsyche von Siebold (Trichoptera: Helicopsychidae) from Brazil
    (Magnolia Press, 2016) Holzenthal, Ralph W.; Blahnik, Roger J.; Calor, Adolfo R.
    Three new species of Helicopsyche subgenus Feropsyche (Trichoptera: Helicopsychidae) from southern and southeastern Brazil are diagnosed, described, and illustrated: Helicopsyche angeloi sp. nov. (Holotype male deposited in MZSP: Minas Gerais, Rio de Janeiro and São Paulo States), H. guara sp. nov. (Holotype male deposited in MZSP: Minas Gerais and Santa Catarina States) and H. lazzariae sp. nov. (Holotype male in MZSP: Paraná State). The first two species are similar to H. cipoensis Johanson & Malm, 2006, and H. timbira Silva, Santos & Nessimian, 2014, in having similarly shaped inferior appendages. However, the new species differs in the morphology and distribution of setae on the inferior appendages and tergum X. Helicopsyche lazzariae sp. nov. is unlike any other described species in the subgenus Feropsyche because of its broad deltoid-shaped inferior appendage and absence of a basomesal process on the inferior appendage. Characters important for diagnosing and describing new species of Helicopsyche (Feropsyche) are discussed. Finally, an updated checklist of the 23 species recorded for Brazil is presented.
