| contents | A new species of the genus Alterosa (Trichoptera: Philopotaminae) from Southeastern Brazil Gabriela Abrantes Jardim Leandro Lourenço Dumas Biología taxonomy caddisfly Atlantic Forest Neotropical region Alterosa nessimiani Philopotamidae is a large caddisfly family with 20 extant genera comprising about 1 000 described species worldwide. Alterosa contains 22 described species distributed in South and Southeastern Brazil. Adults of the genus are very similar in general structure, but are remarkable for their wide variation in male genitalic morphology. The specimens were collected with Pennsylvania light traps and preserved in 80% ethanol. Alterosa nessimiani sp. nov. is described and figured from male specimens collected in streams of Rio de Janeiro state, Southeastern Brazil. The new species is closely related to A. jordaensis Blahnik 2005, from which it can be distinguished by the presence of two spines on the intermediate appendages and by the shape of tergum X. 2012 artículo científico 0034-7744 https://www.redalyc.org/articulo.oa?id=44923872006 en http://www.redalyc.org/revista.oa?id=449 Revista de Biología Tropical application/pdf Universidad de Costa Rica Revista de Biología Tropical (Costa Rica) Num.2 Vol.60 |
