摘要

This study reports a range extension of the Smallscale bonefish, Albula oligolepis Hidaka, Iwatsuki & Randall, 2008, to the southwestern coast of India (n = 3) (236–370 mm standard length) collected from Thengapattanam fishing harbour, Kanyakumari. These specimens were characterized by moderately elongated body, and an orbit diameter slightly less than the interorbital width, a slightly extended terminal anal-fin ray, and fresh coloration is bright silvery white with dark longitudinal lines between dorsal scale rows, black snout tip and posterior margin of caudal fin black, and a faint yellow tinge at the bases of the pectoral and pelvic fins. Albula oligolepis can be clearly separated from its closely related species, A. argentea and A. virgata, based on differences in vertebral number revealed through radiographic analysis, along with counts of pored lateral-line scales, and the extent of pelvic-fin projection relative to the anal opening. This study adds new information on the distribution of A. oligolepis in the west coast of India, providing useful insights for future assessments of its ecological role and potential relevance to coastal fisheries.
