24 specimens of Triops cancriformis from a maleless population living in a rice field of Sibari plain (Cosenza) have been examined. All the animals possess ovario-testes; the degree of hermaphroditism is variable. The testis lobes do not show an uniform distribution along the reproductive system; they are almost exclusively placed in the portion behind the efferent oviduct. On the ground of this observation the Authors think that in Triops there is not a cephalo-caudal maleness gradient, but a progressive reduction of hermaphroditism from the cephalic end.
