Smales, Lesley, 2020, Gastrointestinal nematodes of Paramelomys levipes and P. mollis (Rodentia Muridae) from Papua, Indonesia and Papua New Guinea with the descriptions of three new genera and nine new species (Nematoda), Zootaxa 4861 (4), pp. 544-572 : 567

Nippostrongylinae sp. 1.

( Fig 10 D, E )

Three males and two females were collected from P. mollis from Bichate, Arfak Mountains, Papua, Indonesia AM W. 53149.

Tiny worms: Males 1.8, 2.1 mm long, 43, 47 wide, cephalic vesicle with about 15 annulations, 26 long, oesophagus 220, 230 long, spicules 190–200 long with a small slightly dissymmetric bursa. Females 2.1, 2.1 long, 50, 66 wide, cephalic vesicle 30, oesophagus 260, 290 long, vulva opening 80 from tail tip, tail reflexed ventrally, 20 long, 5– 6 eggs in utero, eggs thin shelled, ellipsoidal 52.8 long, 33.0 wide. Although the morphological characters were consistent with the specimens being a species of Helgenema this could not be confirmed because it was not possible to prepare transverse section of the body and describe the synlophe.
