Abstract

The present paper documents the occurrence of the black-lined sleeper Goby, Valenciennea helsdingenii (Bleeker, 1858) from northern Gulf of Mannar and south Palk Bay, southeast coast of India. This species is characterized by a body with two dark stripes that connect the head and caudal fin and a large dark spot between the third and sixth dorsal fin spines. A total of 6 specimens were collected during the study period from Gulf of Mannar and Palk Bay waters. The present report extends the range of distribution of this species, which was reported earlier from Punnakayal (southern Gulf of Mannar region). This study recommends the need for more taxonomical studies on the cryptic fish species of shallow coastal waters to better understand its diversity and distribution pattern.
