    DNA barcode data confirm new species and reveal cryptic diversity in Chilean Smicridea (Smicridea) (Trichoptera:Hydropsychidae)
    (The North American Benthological Society, 2010) Pauls, Steffen U.; Blahnik, Roger J.; Zhou, Xin; Wardwell, C. Taylor; Holzenthal, Ralph W.
    Mitochondrial deoxyribonucleic acid (mtDNA) sequence data have been both heralded and scrutinized for their ability or lack thereof to discriminate among species for identification (DNA barcoding) or description (DNA taxonomy). Few studies have systematically examined the ability of mtDNA from the DNA barcode region (658 base pair fragment of the 59 terminus of the mitochondrial cytochrome c oxidase I gene) to distinguish species based on range-wide sampling of specimens from closely related species. Here we examined the utility of DNA barcode data for delimiting species, associating life stages, and as a potential genetic marker for phylogeographic studies by analyzing a rangewide sample of closely related Chilean representatives of the caddisfly genus Smicridea subgenus Smicridea. Our data revealed the existence of 7 deeply diverged, previously unrecognized lineages and confirmed the existence of 2 new species: Smicridea (S.) patinae, new species and Smicridea (S.) lourditae, new species. Based on our current taxonomic evaluation, we considered the other 5 lineages to be cryptic species. The DNA barcode data proved useful in delimiting species within Chilean Smicridea (Smicridea) and were suitable for life-stage associations. The data also contained sufficient intraspecific variation to make the DNA barcode a candidate locus for widespread application in phylogeographic studies.

    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.

    Revision of the austral South American species of Mortoniella (Trichoptera: Glossosomatidae: Protoptilinae)
    (Magnolia Press, 2011) Blahnik, Roger J.; Holzenthal, Ralph W.
    Species of Mortoniella are revised for the southern part of the South American continent, including the countries of Brazil, Paraguay, Uruguay, Argentina and Chile. The M. velasquezi species group is diagnosed for the first time and the M. bilineata species group is more critically defined. Males of all species from the region, except M. armata (Jacquemart, 1963), are figured, and a key is provided for their identification. Included in the revision are 11 described species and 22 new species. Previously described species that are redescribed and figured include the following: Mortoniella albolineata Ulmer, 1907; M. argentinica Flint, 1974; M. catarinensis (Flint, 1974); M. collegarum (Rueda & Gibon, 2008); M. guairica (Flint, 1974); M. ormina (Mosely, 1939); M. pocita (Flint, 1983); M. punensis (Flint, 1983); M. teutona (Mosely, 1939) M. unota (Mosely, 1939); and M. wygodzinskii (Schmid, 1958). Mortoniella collegarum, originally described from Bolivia and Argentina, is here reported from Chile, representing the first distributional record of Mortoniella for that country. It is assigned to the M. ormina species group. On morphological considerations, M. argentinica is removed from the M. bilineata species group and left as a species incertae sedis as to species group. Based on its overall similarity to M. argentinica, M. spinulata (Flint, 1991), from Colombia, is removed from the M. leroda species group and left as a species incertae sedis as to species group. New species of Mortoniella described here, followed by their respective areas of distribution, include, for the M. leroda species group: Mortoniella acauda (SE Brazil), M. agosta (SE Brazil), M. asym- metris (Paraguay), M. crescentis (SE Brazil), M. dolonis (SE Brazil), M. guahybae (SE Brazil), M. hystricosa (SE Brazil), M. intervales (SE Brazil), M. latispina (SE Brazil), M. longispina (SE Brazil), M. paraguaiensis (Paraguay), M. parauna (SE Brazil), M. paraunota (Argentina, SE Brazil), M. pumila (SE Brazil), M. pusilla (SE Brazil), M. truncata (SE Brazil), and M. uruguaiensis (SE Brazil, Uruguay); for the M. ormina species group: M. alicula (SE Brazil); and for the M. velasquezi species group: M. bocaina (SE Brazil), M. froehlichi (SE Brazil), and M. tripuiensis (SE Brazil). A new species unplaced as to species group is M. meloi (SE Brazil).

    (Magnolia Press, 2008) Blahnik, Roger J.; Holzenthal, Ralph W.
    The genus Mexitrichia Mosely, 1937 (27 described species) is synonymized with Mortoniella Ulmer, 1906 (22 described species) and a revised generic description is provided for the genus. These species are placed in 4 recognized species groups. Mexican and Central American species of Mortoniella are revised to include 6 species formerly placed in Mex- itrichia and 22 new species from Costa Rica, Panama, and Mexico. New species combinations for these regional species include: Mortoniella florica (Flint, 1974), M. leroda (Mosely, 1937), M. meralda (Mosely, 1954), M. pacuara (Flint, 1974), M. rancura (Mosely, 1954), and M. rovira (Flint, 1974). New species of Mortoniella described here (followed by the country of provenance) include M. akantha (Costa Rica) M. anakantha (Costa Rica) M. aviceps (Costa Rica, Pan- ama) M. brachyrhachos (Mexico), M. buenoi (Mexico), M. carinula (Costa Rica), M. caudicula (Costa Rica), M. falcic- ula (Mexico), M. mexicana (Mexico) M. munozi (Costa Rica, Panama), M. opinionis (Costa Rica), M. panamensis (Panama), M. papillata (Costa Rica), M. pectinella (Panama), M. propinqua (Costa Rica), M. redunca (Costa Rica), M. rodmani (Costa Rica), M. sicula (Costa Rica), M. stilula (Costa Rica), M. tapanti (Costa Rica, Panama), M. taurina (Costa Rica, Panama), and M. umbonata (Panama).

    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.

    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.

    DNA barcoding was intended as a means to provide species-level identifications through associating DNA sequences from unknown specimens to those from curated reference specimens. Although barcodes were not designed for phylogenetics, they can be beneficial to the completion of the Tree of Life. The barcode database for Trichoptera is relatively comprehensive, with data from every family, approximately two-thirds of the genera, and one-third of the described species. Most Trichoptera, as with most of life’s species, have never been subjected to any formal phylogenetic analysis. Here, we present a phylogeny with over 16 000 unique haplotypes as a working hypothesis that can be updated as our estimates improve. We suggest a strategy of implementing constrained tree searches, which allow larger datasets to dictate the backbone phylogeny, while the barcode data fill out the tips of the tree. We also discuss how this phylogeny could be used to focus taxonomic attention on ambiguous species boundaries and hidden biodiversity. We suggest that systematists continue to differentiate between ‘Barcode Index Numbers’ (BINs) and ‘species’ that have been formally described. Each has utility, but they are not synonyms. We highlight examples of integrative taxonomy, using both barcodes and morphology for species description. This article is part of the themed issue ‘From DNA barcodes to biomes’.
