Abstract:
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.
