Cryptogonimidae (Digenea: Trematoda) from Philippine Food Fishes

To date Neochasmus microvatus, (Tubangui, 1928) Tubangui et Masilungan, 1944, is the only known Philippine representative. The topotype is herein described and reported for the second time in the same host species, Glossogobius giurus Buchanan-Hamilton with an additional locality record. Three species previously reported by Yamaguti, namely Paracryptogonimus acanthostomus Yamaguti, 1934, from Japan and Celebes (1934, 1952), Metadena apharei (Yamaguti, 1942) Yamaguti, 1953, from Okinawa (Yamaguti, 1942) and Pseudomentadena celebesensis Yamaguti, 1952, from Celebes ((Yamaguti, 1942) 1952) are here recorded and described from Philippine waters for the first time in similar, if not from the same host species. One new species of Paracryptogonimus Yamaguti, 1934 and one new genus are proposed, and a new combination is made.
