On two new species of the genus Enterobius leach, 1853, from a Colobus monkey.

Abstract

The material described in this paper consists of ten mature males and ten females obtained from the intestine of a Colobus monkey (Colobus sp.) which died on its way to London, from West Africa. The specimens were collected at the London Zoo Prosectorium. On detailed study, they proved to belong to two different, hitherto unknown, species of the genus Enterobius. These two species differ markedly in the length and shape of the spicule and number of caudal papillae. There are six males and a number of females of one species, which is named E. pesteri n.sp and two males of another species, E. inglisi n.sp.
