Abstract

Six species of haplosplanchnids are reported in this study. Haplosplanchnus caudatus (Srivastava, 1939) Skrjabin and Guschanskaja, 1955 was found in large numbers in 8 of 9 Mugil cephalus. H. purii Srivastava, 1939 was found in small numbers in 2 of 9 Liza vaigiensis and 1 of 9 Mugil cephalus. Both of these findings represent a new locality record. Schikhobalotrema southi n. sp. is described from a single specimen from Scarus rivulatus. S. scari n. sp. from the same host is also described from a single specimen. Schikhobalotrema sp. is described but not named because of insufficient data. Hymenocotta mulli Manter, 1961 from Mugil cephalus and Liza vaigiensis is also reported, based on one specimen from each host.

New synonyms: Haplosplanchnus stunkardi Gupta and Ahmad, 1979 is a synonym of H. caudatus (Srivastava, 1939) Skrjabin and Guschanskaja, 1955. H. otolithi Gupta and Ahmad, 1979 is a synonym of H. purii Srivastava, 1939. Neohaplosplanchnus ablennis Abdul-Salam and Khalil, 1987 is transferred to the genus Schikhobalotrema becoming S. ablennis n. comb.

A key to the genus Schikhobalotrema including the new species is included.
