Male (Fig3-5) : Body length 12.8 mmthe pharyngeal tube extending almost equal to the total body length (b=1.02)Tail diameter (body width at the level of urogenital cavity hole) 105μTwo spicules short and flat with different shape and lengthand the long one 160μin lengthwith a ratio of 1.52 between spicule length and tail diameterTail papillae arranged regularly in three rows

Female (Fig. 6-8) : Body length 13.1 mmvagina pear-shapeddistance from anterior to vulva 5.3 mmV=40.1b=1.04

Diagnosis: (1) O. itascensis body length (female 43.7 mmmale 22 mm) considerably longer than that of O. Chongqingensisand the pharyngeal tube

extending approximately 14 of the total body lengthbut in O.chongqingensis

pharyngeal almost equal to body length. (2O. muspratti and O. troglodytis

with uniform spicules in length and shapebut quite different from that of
