A report of the first occurrence of species Dysomma bucephalus Alcock in the Arabian Sea. The species first recorded outside its type locality in the Bay of Bengal. Dysomma bucephalus is described from three adult specimens collected in the Arabian Sea off the Laccadives at a depth of 193 m. The larval form of the species D. bucephalus was first found in the Bay of Bengal near the Nicobar Islands and is also described herein. These findings expand the known range species westward.
