On the synonymy of Pseudagrion bidentatum Morton, 1907, with P. hypermelas Selys, 1876

Abstract

• No new information on Pseudagrion bidentatum has been published since its original description by Morton in 1907 based on a single male from western India. Although this species was already regarded as a synonym of either P. hypermelas Selys, 1876, or P. spencei Fraser, 1922, by Fraser in 1933 it was still treated as a valid species on later checklists. Basedv on a study of the original description and the holotype held at the National Scottish Museum, Edinburgh, we conclude that P. bidentatum is a junior synonym of P. hypermelas.
