title: A re-description of Physocephalus dromedarii stat. nov. (Nematoda: Spirocercidae), an abomasal nematode of dromedaries (Camelus dromedarius).
abstract: Physocephalus dromedarii stat. nov. was found in the abomasum of two adult female dromedaries originating from a farm in Dubai. Previously, this nematode has been misidentified as a subspecies of Ph. sexalatus but morphological differences are striking enough for it to be upgraded to a species. Physocephalus dromedarii is larger than Ph. sexalatus and has longer spicules. There are 20-22 oblique crests at the ventral surface between the caudal alae of the male compared to 7-8 in the case of Ph. sexalatus. The most significant differences are the presence of two pairs of papillae between cloaca and postcloacal plate of the male and the existence of a swelling in the second half of the female body formed by loops of both uterine horns.
