RESUMO
Females of the genus Probstmayria, collected in feces of wild Chimpanzees and Gorillas, living in the Lope-Okanda reserve in Gabon, are described. The cephalic structures of P. gombensis File, 1976 from Chimpanzee and P. gabonensis n. sp. from Gorilla are similar to those of the other species of the genus. In contrast, the cephalic structures of P. inversa n. sp. from Chimpanzee and P. goodallae n. sp. from Gorilla are unusual; they have an inverse symmetry (one ventral lip and two latero-dorsal lips). The original characteristics of the genus Probstmayria are analysed.

Ichthyocephalus anadenoboli n. sp. ( Rhigonematidae ; Nematoda) from Anadenobolus politus ( Porat ) ( Rhinocricidae ; Diplopoda ) from Guadeloupe is described. The new species most closely resembles I. egleri since both sexes are of approximately the same size and the spicules are markedly unequal; it is distinguished in having a much longer right spicule, by the form of the extremity of the left spicule and by the presence of a vaginal sac opening into the vagina at its junction with the uteri. In addition certain aspects of spermiogenesis in the new species are studied. Maturation of spermatids occurs in two phases, one in the testis and seminal receptacle of males, the second in the vaginal sac in females. The second phase involves profound changes in form as well as nuclear transformation. It is suggested that the vaginal sac observed in certain species of Rhigonema as well as the " bourse copulatrice " of certain Tetrameres spp. and Maupasina weissi , like that of Ichthyocephalus anadenoboli , are specialized to accommodate the final stages of spermiogenesis.
