Cotylascaris thylacini: a synonym of Ascaridia columbae

Published online by Cambridge University Press:  06 April 2009

The writer (Sprent, 1971) described four female specimens of an ‘ascaridoid’ nematode from a vial labelled ‘Tasmanian Marsupial Wolf’. The name Cotylascaris thylacini was proposed, in spite of there being no male specimens available. This was because no other genus among ascaridoids was known by the writer to possess cup-like cuticular structures on the margins of the lips and also because the thylacine (Thylacinus cynocephalus) is considered to be on the verge of extinction, if not extinct already.
