Abstract

Laubuka tenellais a new species characterized by the colour pattern, consisting of short dark vertical bars anteriorly on the side, and a dark lateral band posteriorly on the side, combined with a relatively short pelvic fin and 29–30 lateral-line scales. It is separated from otherLaubukaanalysed by minimum 9 % uncorrectedp-distance in the mitochondrial COI gene. The type series is composed of specimens from small streams in the Cox’s Bazar District in Bangladesh (the type locality), and the Thandwe River drainage in western Myanmar.Laubuka brahmaputraensisis strongly indicated to be a junior synonym ofL. laubuca, the second known species ofLaubukain Bangladesh.Eustira ceylonensis, currently in the synonymy ofDevario malabaricus, is a valid species ofLaubuka.
