Abstract

Although four species of the engraulid genus Thrissina (often regarded as Thryssa) have previously been recorded from waters around Taiwan, Thrissina encrasicholoides (Bleeker, 1852), known from the eastern Indian and western Pacific Oceans (north to the Philippines), has not been to date. However, two specimens (100.1 and 100.6 mm standard length) of T. encrasicholoides were collected from south-western Taiwan. Their morphology and fresh coloration are described, the former being largely consistent with previous descriptions of the species: short maxilla, its posterior tip blunt, slightly beyond anterior margin of preopercle; 14 or 17 keeled scutes; and one scute weakly developed and lacking a ventral edge projection, immediately behind the isthmus. The specimens represent the first record of the species from Taiwanese waters and the northernmost record of the species.
