A NEW SPECIES OF DORCOPSINEMA MAWSON, 1977 (NEMATODA, CLOACINIDAE) FROM THE TREE KANGAROO DENDROLAGUS-MBAISO (MARSUPIALIA, MACROPODIDAE) FROM IRIAN-JAYA, INDONESIA AND NEW HOST RECORDS FOR DORCOPSINEMA-DENDROLAGI
Lr. Smales, A NEW SPECIES OF DORCOPSINEMA MAWSON, 1977 (NEMATODA, CLOACINIDAE) FROM THE TREE KANGAROO DENDROLAGUS-MBAISO (MARSUPIALIA, MACROPODIDAE) FROM IRIAN-JAYA, INDONESIA AND NEW HOST RECORDS FOR DORCOPSINEMA-DENDROLAGI, Systematic parasitology, 38(2), 1997, pp. 131-135
A new species, Dorcopsinema mbaiso, from Dendrolagus mbaiso from Irian
Jaya, Indonesia is described. It is most similar to D. dendrolagi, th
e other species of Dorcopsinema occurring in tree-kangaroos, but can b
e distinguished from it in having a distinct fleshy collar surrounding
the buccal capsule, deirids close to the collar, shorter spicules (1,
055 mu m 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. dend
rolagi, and the dorsal ray with vestigial lateral branches versus long
er 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 mu m ver
sus 790 in D. dorcopsis), the dorsal ray with very short lateral branc
hes rather than one third the length of the dorsal ray as in D. dorcop
sis, and shorter spicules (1,055 mu m versus 2,150 in D. dorcopsis). N
ew host records for D. dendrolagi are Dendrolagus scottae and D. inust
us, new localities are Tembagapura in Irian Jaya, Indonesia and the We
st Sepik region of Papua New Guinea. A key to the species of Dorcopsin
ema is given.
