Abstract

Dicrania Lepeletier & Audinet–Serville, 1828 (Coleoptera, Scarabaeidae, Melolonthinae) is composed by 38 South American species of which 31 occur in Brazil. In this revision, seven synonymies were proposed: Dicrania hirsuta Frey, 1965 n. syn. for Dasyus collaris Lepeletier & Audinet–Serville, 1828, Dicrania morio Kraatz, 1895 n. syn. and D. rugosipennis Blanchard, 1850 n. syn. for D. velutina Laporte, 1832, D. plaumanni Frey, 1972 n. syn. for D. notaticollis Moser, 1921, D. popei Frey, 1972 n. syn. for D. setosicollis Frey, 1942, D. metzi Kraatz, 1895 n. syn. and D. unicolor fulvicollis Kraatz, 1895 n. syn. for D. unicolor Kraatz, 1895; two species were revalidated: Dicrania dichroa Perty, 1933 reval. former synonymy of D. nigra Lepeletier & Audinet–Serville, 1828, and D. quadricristata Guérin–Méneville, 1844 reval. former synonymy of D. velutina; five species were described: Dicrania bllix n. sp., D. cocculina n. sp., D. cruralis n. sp., D. hexaphylla n. sp., and D. triacria n. sp.; and D. martinezi Frey, 1972 and D. parvula Frey, 1970 were transferred to Compsodactylus n. gen. Keys to genera and species, notes on biology of some species, geographic distribution and illustrations were provided.
