Abstract

A large-tooth flounder, Pseudorhombus diplospilus Norman (1927) (Pleuronectiformes: Paralichthyide), is reported from east coast of India based on a single specimen collected from Royapuram fishing harbor, Chennai, Tamil Nadu with detailed meristic and morphometric study. This forms the ninth species in the genus Pseudorhombus and the second species in having palmate gill rakers from Indian waters. With this report of P. diplospilus , its western limit of distributional range is extended from Indonesia and west Australia to east coast of India.
