The plagioporine opecoelids Helicometra fasciata (Rudolphi, 1819) Odhner, 1902, and Macvicaria crassigula (Linton, 1910) Bartoli, Bray, and Gibson, 1989 have been reported from fishes in expansive geographic regions, disjointed from their type localities. New material of M. crassigula was collected from near its type locality as well as specimens resembling Helicometra fasciata sensu lato from three triglids in the Gulf of Mexico. Comparisons of the ribosomal DNA (rDNA) sequences, comprising the partial 18S rDNA, internal transcribed spacer region (= ITS1, 5.8S, and ITS2), and partial 28S rDNA gene, from M. crassigula and Helicometra fasciata sensu lato in the Gulf of Mexico were made with sequences deposited in GenBank from those species from the Mediterranean Sea. Results reveal that M. crassigula sensu stricto from the Gulf of Mexico is distinct from the two cryptic species of M. crassigula sensu lato from the Mediterranean Sea and Helicometra fasciata sensu lato in this study differs from H. fasciata sequences from the Mediterranean Sea, thus Helicometra manteri sp. nov. is described.

A new species of opecoelid trematode, Pseudopecoelus brayi sp. nov. is reported from the holocentrid fish, Myripristis kuntee collected from off Visakhapatnam coast, Bay of Bengal. The new species differs from related species by a combination of characters such as elongate body, deeply lobed gonads, tubular sinuous seminal vesicle extending up to the posterior border of ventral sucker, presence of a short cylindrical cirrus sac enclosing the cirrus and the vitelline zone extending anterior to ventral sucker. This is the 7th species of the genus to be reported from Indian marine fishes and the fifth species from holocentrid fishes. A key for separation of the species of Pseudopecoelus is given.
