ABSTRACT

Drosophila (Drosophila) eleonorae, sp. n. (Type-locality: "Caverna Pedra da Cachoeira", Altamira, Pará, Brazil), a cave-dwelling fly is described, illustrated and compared to a closely related species, the cosmopolitan D. repleta Wollaston. Although morphologically distinct they are homosequential regarding their polythene chromosome banding pattern and have an identical constitutive heterochromatin distribution in the mitotic metaphase chromosomes. Adult specimens of D. eleonorae, sp. n. were collected in several caves located in five states of northern, central and southeastern Brazil (Pará, Goiás, Mato Grosso do Sul, Minas Gerais and São Paulo). Twenty-one imagines emerged in the laboratory from bat-guano collected in a cave of central Brazil. Attempts to produce interspecific hybrids with D. repleta were unsuccessful.

Keywords: Bat-guano-breeding Drosophila; D.repleta; Drosophilidae.
