Abstract
AbstractFive species of nematode were collected from the digestive tracts of 10 Coccymys ruemmleri from Papua New Guinea. Montistrongylus giluwensis sp. nov. can be distinguished from its congener by its size, in having more ridges in the synlophe, longer spicules and the form of the cuticle on the female posterior end. Syphacia (S.) coccymyos can be distinguished from all other species in the subgenus by having a laterally extended dorso-ventrally constricted oval cephalic plate and both cervical and lateral alae, together with the combination spicule length and egg size. The helminth assemblage had similar species richness to that of Chiruromys vates with Odilia mackerrasae the only species in common.
