Abstract
A new species, Dorcopsinema mbaiso, from Dendrolagus mbaiso from Irian Jaya, Indonesia is described. It is most similar to D. dendrolagi, the other species of Dorcopsinema occurring in tree-kangaroos, but can be distinguished from it in having a distinct fleshy collar surrounding the buccal capsule, deirids close to the collar, shorter spicules (1,055 µm versus 1,420 in D. dendrolagi), the dorsal lobe of the bursa longer than the lateral lobe rather than the same length as in D. dendrolagi, and the dorsal ray with vestigial lateral branches versus longer lateral branches in D. dendrolagi. It can be distinguished from D. dorcopsinema occurring in Dorcopsis muelleri in having six, not eight perioral cuticular elements, deirids close to the collar (115 µm versus 790 in D. dorcopsis), the dorsal ray with very short lateral branches rather than one third the length of the dorsal ray as in D. dorcopsis, and shorter spicules (1,055 µm versus 2,150 in D. dorcopsis). New host records for D. dendrolagi are Dendrolagus scottae and D. inustus, new localities are Tembagapura in Irian Jaya, Indonesia and the West Sepik region of Papua New Guinea. A key to the species of Dorcopsinema is given.
