The specimens examined in this study are deposited at the Coleção Entomológica Pe. Jesus Santiago Moure, Universidade Federal do Paraná, Curitiba (DZUP), Coleção Entomológica Prof. José Alfredo Pinheiro Dutra, Departamento de Zoologia, Instituto de Biologia, Universidade Federal do Rio de Janeiro, Rio de Janeiro, (DZRJ), Museu de Zoologia da Universidade de São Paulo, São Paulo (MZUSP), and Departamento de Entomologia, Museu Nacional, Universidade Federal do Rio de Janeiro, Rio de Janeiro (MNRJ). The terminology follows mainly
Small size, 6.0 to 9.0 mm. Head, in dorsal view, not produced, median length of crown approximately one-third of interocular width; anterior margin of crown broadly rounded and parallel to anterior margin of pronotum; transocular width of head slightly narrower than maximum pronotum width. Ocelli equidistant between eyes and median line, located near anterior margin of crown. Head, in lateral view, with crown-face transition rounded and with several parallel striae. Pronotum moderately declivous; head and pronotum in continuous slope. Male pygofer with or without dorsal processes; when present, variable in morphology. Aedeagus with atrial processes; shaft commonly greatly recurved near base.

Holotype male: “Vilhena, Rondônia\Brasil XI-1960\M. Alvarenga”, DZUP. Paratypes: 1♀, same data of holotype, DZUP; 1♂, “Vilhena, RO [Rondônia]\27/12/1986\C. Elias, leg.\Polonoroeste”, DZUP; 2♂, “Sinop, Mato Grosso\Brasil X/1975\M. Alvarenga”, DZUP; 2♂, same data, DZRJ; 2♂, same data, MNRJ; 1♂, “Jacareacanga\Pará Brasil X-1969\M. Alvarenga leg.”, DZUP.
The new species name is an honor of Moacir Alvarenga, Major of the Brazilian Air Force, great collector of insects, whose inestimable material, collected on decades of 1950–1980 in areas which today are degraded, is still the basis for many scientific studies.
