Female genitalia and taxonomic relationships ofMacaca assamensis

Abstract

Study of ten females ofMacaca assamensis provides information concerning reproductive anatomy, postnatal development and systematic relationships of this species. The sexual skin is conspicuously inflated in adolescentM. assamensis; during pregnancy smaller sexual swellings are present; during lactation the sexual skin is uninflated and marked by a sharply defined dark blue circumanal triangle. In the vulva of infant and adolescentM. assamensis a ventral vestibular fold protrudes between the vaginal orifice and the recessed urethral orifice; in postadolescent specimens the ventral vestibular fold is absent and a urethral papilla is present. The lining of the vagina is spiny in prepregnantM. assamensis and rugose to papillate in other phases of the cycle. The cervix is greatly enlarged and secretory in adolescentM. assamensis; it remains large before and during pregnancy and becomes constricted during lactation. The cervix inM. assamensis is similar to that inM. sinica andM. radiata. This supports previously reported penial evidence of close relationship between these species. Penial structure inM. thibetana indicates that this species also belongs to thesinica-radiata-assamensis group. In these four species latitudinal variation of body size and tail length apparently conforms toBergmann's rule andAllen's rule.
