Eight helminth taxa, including an acanthocephalan (Centrorhynchus sp.) and 7 nematode species, were identified from material in held in the South Australian Museum Australian Helminthological Collection. All the specimens were collected from 3 individuals of Echymipera kalubu Fischer and a single Echymipera sp. at 25% prevalences, from Papua New Guinean localities. The nematodes were identified as follows: a heterakid Heterakis balamukensis Smales, 2023, known only from E. kalubu; a trichurid, most likely Trichuris peramelis Baylis, 1932; the trichostrongyloids Mackerrastrongylus peramelis (Johnston & Mawson, 1938) and Peramelostrongylus skedastos Mawson, 1960; and a seuratid, Linstowinema sp., likely Linstowinema latens Smales, 1997, the latter 4 species being also found in Australian bandicoots. The physalopterid Physaloptera echymipera n. sp. could be distinguished from all the physalopterids known from Australian and Indonesian hosts by a suite of characters including esophagus length, spicule length, vagina length, and egg size. The seuratid Owenema mikosi n. gen., n. sp. was distinguished by having, among other characters, longitudinal rows of tiny spines along the body, a buccal ring with 4 teeth, the proximal end of the esophagus ornamented, short spicules smaller than the gubernaculum, a simple ovejector, and 4 uteri. A comparison of the helminth community, albeit from a small host sample, with those known from Australian bandicoots indicated that the components of their communities were similar. Isoodon macrourus, primarily an Australian bandicoot, and E. kalubu, for example, frequent similar habitats in Papua New Guinea and share several helminth species.
