Probstamyria gombensis sp. n. (Nematoda: Atractidae) from the chimpanzee.

The worm is distinguished by the presence of both unequal spicules and a gubernaculum in the male and also the elongated nipplelike tip of the right spicule. P. gombensis was found to be a common parasite within a troop of feral chimpanzees living in Gombe National Park, Tanzania.
