New distributional record of Istigobius diadema (Steindachner, 1876) and Lobotes surinamensis (Bloch 1790) from the Pulicat lagoon, India

The present study records spectacled sand-goby Istigobius diadema (Gobiidae) and tripletail Lobotes surinamensis (Lobotidae) for the first time from Pulicat lagoon, India. Morphological and meristic characters for both the species are described herein. This study finds the current observations as new distributional records for the above two species, thereby adding two more additional species to the ichthyofaunal diversity of Pulicat lagoon.
