Nippostrongylinae

Smales, L. R., 2014, Gastrointestinal helminths (Cestoda, Chabertiidae and Heligmonellidae) of Pogonomys loriae and Pogonomys macrourus (Rodentia: Muridae) from Papua Indonesia and Papua New Guinea with the description of a new genus and two new species, Zootaxa 3889 (1), pp. 92-106 : 95

Nippostrongylinae species 1

( Figs 1–3 )

Three females from P. loriae collected at Doma Peaks at 2400 m, Southern Highlands Province 13. iv. 1978 by A. B. Mirza and Bin Yuo, BBM NG 105735B.

Coiled worms, 5.2–6.5 mm long, 82.5–120.6 wide; synlophe at mid body, 10 continuous ridges in 2 fields of 4 dorsal smaller and 6 ventral larger ridges. Cervical vesicle 54.4–66.4 long; oesophagus 430–620 long, excretory pore 360–520; deirids 520 from anterior end. Posterior end neither twisted, nor reflected back posteriorly nor with prepuce; vulva 155–330 from tail tip; ovejector with vagina about 30, vestibule 100, sphincter 55, infundibulum 40; tail conical, 47–50; eggs in utero 61.2–79.2 by 34– 49.5.

The exact orientation of the ridges of the synlophe could not be determined but showed a similarity to that of Nippostrongylinae species 3, partially described from Paramelomys rubex (Thomas) suggesting that these specimens might represent another species of the same genus ( Smales & Heinrich, 2010).
