Two Nerocila species parasitizing Pomadasys maculatus from Nagapattinam, Southeast coast of India.

Two species of Cymothoidae (Nerocila loveni and Nerocila sundaica) were collected on the host fish Pomadasys maculatus from the Nagapattinam coast. Pomadasys maculatus is a new host for these parasitic isopods not previously recorded in the world. Nerocila loveni was mainly attached on the caudal peduncle of the fish and N. sundaica was collected from the pectoral fin and the body of the host. For N. loveni and N. sundaica, the prevalence reached 28.70 and 26.08 % respectively. One parasite was collected per host fish.
