Parasabanema sp.

( Fig 10 A–C)

Four males and the posterior end of one female were collected from three individuals of P. mollis from Bichate, Arfak Mountains, Papua Indonesia by T . Flannery 10. x. 1992, AM W. 53140, W. 53141.

These males had a synlophe of about 30 small even ridges, characteristic of Parasabanema spp., as was the morphology of the bursa and spicules. The worms, however, were smaller 2.0– 2.4 mm long compared with 5.4–8.5 mm for P. szalayi and 3.1–4.3 mm for P. sene and with shorter spicules 320–440, 6% of body length compared with 440–550, 7.2 % for P. szalayi and 250–310, 8 % for P. sene . The female vulva opened 55 from the tip of the 20 long tail; the vestibule was the longest element of the ovejector followed by the vagina, 75, the infundibulum, 50, and the sphincter, 30 long. These morphometric differences suggest that the specimens from Bichate represent a new species.
