Troglostrongylussubcrenatus (Railliet & Henry, 1913) Fitzsimmons, 1964

This is a metastrongyloid nematode parasite of the lungs of felids that is related to Aleurostrongylusabstrusus and which was originally reported from a leopard in the Congo. This nematode has ben reported on a single occasion from a cat in Africa, Blantyre, Nyasaland (Fitzsimmons, 1961). The males of this species have long slender spicules and the vulva of the female is posterior to the middle of the body rather than near the anus as in Aelurostrongylus. The adults are 10 to 23 mm long; about twice the length of the adults of Aelurostrongylus abstrusus. The life cycle of a related parasite Troglostrongylus brevior was described by Gerichter (1948, 1949). The adults of Troglostrongylusbrevior are found in Felis ocreata and Catolynx chaus. First-stage larvae in the feces enter a suitable mollusk, and infective larvae are present in about eight days. The patent period for this other species was found to be 28 days in a kitten fed snails containing infective larvae.
