Trichostrongylus cramae n. sp. (Nematoda), a parasite of bob-white quail (Colinus virginianus)

Abstract

Cram (1925, 1927) incorrectly identified as T. pergracilis (now a synonym of T. tenuis) what was in reality an undescribed species in Colinus virginianus. Trichostrongylus cramae n. sp. is proposed for T. pergracilis sensu Cram, 1927 nec Cobbold, 1873 from C. virginianus from USA. It differs from T. tenuis (Mehlis in Creplin, 1846) as regards the cuticular striation, the relative distances between the second, third and fourth bursal papillae and the configuration of the dorsal ray. Red grouse (Lagopus scoticus), the type host of T. pergracilis, was in fact found to be parasitized by T. tenuis, confirming the synonymy of T. pergracilis and T. tenuis.
