description 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. Rev. Biol. Trop. 60 (2): 577-580. Epub 2012 June 01.<br>Philopotamidae es una familia grande de tricópteros la cual está actualmente compuesta por 20 géneros y cerca de 1 000 especies descritas en todo el mundo. El género Alterosa posee 22 especies descritas y están distribuidas en el sur y sureste de Brasil. Los adultos del género son muy similares en su estructura general, pero se diferencian por su amplia variación presente en la morfología de la genitalia masculina. Los ejemplares fueron recolectados en trampas luminosas Pennsylvania y conservados en etanol al 80%. Alterosa nessimiani sp. nov. es descrita e ilustrada basada en ejemplares machos recolectados en el estado de Río de Janeiro, sureste de Brasil. La nueva especie es similar a A. jordaensis Blahnik, 2005, pero puede ser diferenciada por la presencia de dos espinas en los apéndices intermediarios y por la forma del tergo X.
