Schistomeringos japonica (Family Dorvilleidae) -- A new record of polychaete from Pakistani coast.

A marine polychaete worm, of the genus Schistomeringos Jumars, 1974, is hereby reported for the first time from the coasts of Pakistan. Several specimens of Schistomeringos japonica (Annenkova, 1937) were collected from settlement panels deployed at Korangi Fish Harbour (24°48´8.34" N; 67°17´60" E), Karachi, Pakistani coast. S. japonica is closely related to S. rudolphi (Delle Chiaje, 1828) but differs in having furcate chaeta from the first, not the second, pair of parapodia. S. rudolphi has been reported from the Red Sea. Detailed description and illustrations of S. japonica, based on Pakistani materials, are given herein. [ABSTRACT FROM AUTHOR]
