Abstract - The cavernicolous species of the genus Dissochaetus were surveyed. One new species was collected and is described - Dissochaetus vanini sp. n., from several caves from Minas Gerais, Paraná and São Paulo States - type locality: Gruta da Lacinha, Paraná. Four Dissochaetus species were collected both in caves and in the epigean environment: D. hetschkoi, D. murrayi, D. villosus and D. vanini; and one (D. maculatus) was collected only in the epigean environment. Colonization of caves is discussed, and dispersion seems to be mainly by epigean routes. A checklist of all known species and collecting localities is given.
