DUMAS, LEANDRO L.. Contulma vascaina sp. n. (Insecta: Trichoptera: Anomalopsychidae), a new species from Rio de Janeiro state, southeastern Brazil. An. Acad. Bras. Ciênc. [online]. 2018, vol.90, n.3, pp.2921-2926.  Epub 25-Jun-2018. ISSN 0001-3765.  http://dx.doi.org/10.1590/0001-3765201820170802.

The caddisfly genus Contulma Flint, 1969, with 30 described species, is endemic to the Neotropics. In addition to the five species currently recorded from Brazil, a new species of Contulma is described and illustrated in this work. Contulma vascaina sp. n. is similar to C. sana Jardim and Nessimian, 2011 in prominent, slender and rod-like posterolateral lobe of segment IX, but the new species has a shorter posterolateral lobe, with long, spine-like seta apically. Contulma vascaina sp. n. can also be characterized by the presence of a large, hood-like sclerotized plate on the endothecal phallic membrane. The female genital structure is also described and illustrated.

Palavras-chave : Atlantic Forest; caddisfly; Contulma; female description; taxonomy.
