Thylacicleidus serendipitus n.gen., n.sp. is proposed for material from the green puffer, Tetraodon fluviatilis Hamilton-Buchanan, 1822, from Indonesia. Thylacicleidus is distinguished from other ancyrocephalid genera by the following combination of characters: a distinctive tegumentary structure, with the body surface covered with numerous small transverse ridges; a sinistral vaginal opening; hamuli with a shortened shaft and heavy blade; ventral hamuli with reduced deep root; ventral transverse bar with lateral extremities sharply deflected posteriorly; and an association with hosts of the family Tetraodontidae. The only ancyrocephalid genus previously recorded from tetraodontids is Haliotrema Johnston and Tiegs, 1922. The status of Haliotrema is discussed and it is suggested that, because of morphological variability within Haliotrema and an extremely wide host spectrum, the genus is almost certainly polyphyletic and in need of taxonomic revision.
