A Preliminary Revision of the Genus Pharyngostrongylus Yorke and Maplestone, 1926

Extract
The genus Pharyngostrongylus was proposed by Yorke and Maplestone, 1926, for some strongyle nematodes from Macropus sp., which they named P. macropodis. Later in the same year, Mönnig described another new strongyle nematode Spirostrongylus australis from Macropus rufus, erecting a new genus for it. The generic name of Mönnig's species was changed to Rugopharynx Mönnig, 1927, the first being pre-occupied (Spirostrongylus Yorke and Maplestone, 1926). In 1929, Wood gave a description of some specimens collected from Macropus woodwardi which were identified as Rugopharynx australis Mönnig. Wood also pointed out that “the presence of a buccal capsule, a corona radiata, and a fairly large and differentiated dorsal lobe to the bursa copulatrix seem to exclude it from the Trichostrongylidae where Mönnig has placed it and he considers that it belongs to Trichoneminae.” Furthermore, he transferred that species to the genus Pharyngostrongylus on the basis of “the arrangement of its buccal capsule and its markedly ringed pharynx” considering Rugopharynx a synonym of Pharyngostrongylus.
