The Gastrointestinal Helminths of Chiruromys vates (Rodentia: Muridae) with the Description of a New Species (Nematoda: Heligmonellidae) from Papua New Guinea

摘要

Four species, all heligmonellid nematodes, were collected from the digestive tracts of 30 Chiruromys vates from a single location in Papua, New Guinea. Hassanuddinia chiruromyos n. sp. differs from its congener in having 2 hypertrophied ventral ridges in a synlophe of 10-12 midbody ridges. A putative new species of Paraheligmonellnoides had 27 midbody ridges in the female synlophe, more ridges than in any other congener. The regionally distributed Odilia mackerrasae, and an unidentifiable female with 9 synlophe ridges midbody, completed the apparently depauperate helminth assemblage. The composition of this assemblage indicated links between the Sahul, Sunda, and Oriental Regions
