Kalubustrongylus arsoensis gen. et sp. n. (Trichostrongylidae: Filarinematinae) and Other Nematodes Belonging to the Suborder Trichostrongylina Parasitic in the Common Spiny Bandicoot, Echymipera kalubu, of Papua Indonesia.

Purpose: The present paper reports the nematodes of the suborder Trichostrongylina collected from the common spiny bandicoot, Echymipera kalubu, in Arso, Papua Indonesia. The description of Kalubustrongylus arsoensis gen. et sp. n. (Trichostrongylidae: Filarinematinae) is given herein.

Materials And Methods: The specimens were collected from three common spiny bandicoots at Arso, Papua Indonesia, captured using traditional snap traps in August 1993. The new taxon is described and illustrated by light and scanning electron microscopy. Type and voucher specimens were deposited in the Museum Zoologicum Bogoriense (MZB), Bogor, Indonesia.

Results: The new genus Kalubustrongylus is classified as a member of the subfamily Filarinematinae in the family Trichostrongylidae by having a bilaterally symmetrical synlophe and an uncoiled body, and by lacking a cephalic vesicle. It resembles Peramelistrongylus but is distinguished by having additional ridges in the synlophe, an elliptical bursa, an apically divided dorsal ray and minute extra-dorsal rays. Besides Ka. arsoensis, Mackerrastrongylus biakensis, Peramelistrongylus skedastos, Beveridgiella spp., Dessetostrongylus sp. and Herpetostrongylinae sp. were collected. Dessetostrongylus is recorded for the first time outside of Australia and from non-dasyurid marsupials.

Conclusions: The present findings add a genus to the three genera previously known in the subfamily Filarinematinae in the family Trichostrongylidae.
