Morphology and Anatomy:

With general characteristics of the genus
Small nematodes, 2-5 mm long, forming sinistral ventral coils.
Cephalic vesicle present.
Mouth triangular, surrounded by 4 cephalic papillae and amphidial pores.
Cuticle finely striated;
Synlophe well developed with pointed ridges,from just posterior to cephalic vesicle and ending anterior to bursa in male and at vulval level in female. 14 ridges present at mid-body; type A carene supported by hypertrophied left lateral ridge; axis of orientation of ridges passing through ventral-right and dorsal left sides, inclined at 45 degr. from sagittal axis; ridges 2 to 4 well developed; ridges 5 and 6 larger than other ridges in dorsal side of axis of orientation;
Esophagus club-shaped.
Nerve ring slightly posterior to midlevel of esophagus; excretory pore and deirids at midlevel between nerve ring and esophago-intestinal junction.

	Females: Monodelphic, prodelphic Vulva posterior, about 120 um from tail tip. Cuticle distended at prevulval level forming small prepuce in some worms. Tail conical with blunt end.

Males: Bursa asymmetric with larger right lobe partly folding over dorsal lobe. See original description for detail;s of bursal rays. Differs from all other Nippostrongylus spp. by having the ray 3 widely diverged distally from the ray 4 in the left lobe of bursa. Spicules alate, similar in length, distally united, not strongly twisted, to form pointed end, Gubernaculum small Ref: Hasegawa et al., 2017

Collected from the small intestine of Maxomys whiteheadi (Rodentia: Muridae) from Riau, Sumatra, Indonesia. A nematode with similar characteristic was collected from Niviventer cremoriventer in Bukit Soeharto, Kalimantan, Indonesia.
