This species is yellowish-brown in colour.The body is slender with swelling cuticle.The males are 13.757—21.000mm in length,0.179—0.214 mm in width near middle of the body and 0.102—0.187mm wide before the bursa.All rays of the bursa which is well developed are distinct, blunt and round at the end,without reaching the bursal edge.The dor- sal ray which is short and broad,is divided into tetrafurcation.The extero-dorsal rays are curved.The lateral rays riSe from a common stalk, but the antero-lateral ray is longer than medio-lateral and the postero- lateral ones.The postero-lateral is bud-shaped prominency and the shor- test.The ventral ray which riscs from a same stalk,divides into bifurc- ation in the middle. The ventro-ventral ray with a pine-like prominence at the centre of the end edge is longer than the latero-ventral ray.The spicules are equal, With a fine transversely striated ala,0.316—0.374mm long,yellowish-brown in colour and bow-shaped curve, the middle width 0.007—0.009mm,and maximum width at anteral extremity 0.010—0.019mm. Gubernaculum is club-shaped,which is thin and hook-shaped at the ant- eral extremity and slightly broader and larger at the end,0.047—0.080mm in length and 0.007mm in maximum width near the end.The females are 28.4—53.2mm in length and 0.259—0.332mm in width near middle of the body. The vulva which is situated in the posterior part of the bo- dy,is 0.143—0.182 mm from the caudal extremity. The anus is 0.025— 0.071mm from the caudal expremity.The first-stage larva is 0.289-0.328 mm in length with an undulated tail. NO dorsal spine is found.
