Contulma vascaina sp. n. (Insecta: Trichoptera: Anomalopsychidae), a new species from Rio de Janeiro state, southeastern Brazil 42
DUMAS,LEANDRO L..
ABSTRACT 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.

Two new species and updated checklist of Oxyethira Eaton, 1873 (Trichoptera, Hydroptilidae) from Brazil 42
ROCHA,ISABELA C.; DUMAS,LEANDRO L.; SOUZA,WAGNER R.M..
ABSTRACT Two new species of Oxyethira Eaton, 1873 are described: Oxyethira cascadanta sp. n. and Oxyethira quadrilobata sp. n. Description and illustrations of the new species are provided based on specimens collected in Parque Nacional da Serra da Canastra, Minas Gerais State, Southeast Brazil. Both species are assigned to the subgenus Loxotrichia but differ from other species mainly in morphology of the subgenital plate, subgenital processes and inferior appendages. Additionally, we provide an updated checklist of the Oxyethira species from Brazil.
