Synaptobothrioides sardinellae n. g., n. sp. (Digenea: Hemiuridae) from the blacktip sardinella Sardinella melanura (Clupeidae) off Fiji, and records of two other hemiuroids in Fijian waters

摘要

Synaptobothrioides sardinellae n. g., n. sp. is described from Sardinella melanura off Fiji. The new genus differs from other plerurine hemiurid genera in having entire or angular, rather than lobed to digitiform, vitelline masses. It appears closest to Synaptobothrium, but differs in the lack of a presomatic pit and the presence of tegumental plications. Lecithochirium kawakawa from Euthynnus affinis and Thulinia microrchis from Siganus spinus are reported from off Fiji.
