Troglostrongylus subcrenatus

From Felipedia

Troglostrongylus subcrenatus is a metastrongyloid nematode parasite of the lungs of felids that is similar to Aelurostrongylus abstrusus.

As with Bronchostrongylus subcrenatus, the male has very long spicules and the vulva of the female is posterior to midbody rather than near the anus. The adults are about a cm long.

The life cycle of the related species, Troglostrongylus brevoir, which lives in the bronchi of wild felines around the Dead Sea has been shown to utilize gastropod intermediate hosts[1]. The feeding of infective larvae to domestic kittens produces patent infections in about a month.
