Nippostrongylinae

Smales, L. R. & Heinrich, B., 2010, Gastrointestinal nematodes of Paramelomys rubex (Rodentia: Muridae) from Papua Indonesia and Papua New Guinea with the descriptions of three new genera and four new species of Helligmonellidae and Herpetostrongylidae (Nematoda: Trichostrongylida), Zootaxa 2672 (1), pp. 1-28 : 6

Nippostrongylinae species 2

( Figs 3–7 )

A male from a host collected at Siyoubrig , Mokwan area , Arfak Mts, and a female also from the Mokwan area, Papua, Indonesia, both on the 10. X. 1992 by T . Flannery & L. Szalay AM W.36762, W.36767.

Relatively long thin worms, synlophe of about 20 ridges.

Male: 5500 long, 56 wide; cervical vesicle 43 long; oesophagus 230 long; deirid and excretory pore at same level, 190 from anterior end. Bursa relatively large, dorsal lobe shorter than lateral lobe. Genital cone not heavily sclerotised. Spicules filiform, tips simple, 450 long. Gubernaculum 30.

Female: 5900 long, 67 wide; cervical vesicle 50 long; oesophagus 260 long; deirids and excretory pore about 170 from anterior end. Posterior end reflected ventrally; vulva 50 from tail tip, tail blunt, conical, 20 long; eggs, row of 8 in utero 66.0–69.3 by 26.4–33.

The combination of relatively long thin body and spicule length and a synlophe without any noticeably larger ridges distinguished these worms from others found in P. rubex in this study and from all other described genera in the subfamily.
