Abstract

We provide a detailed description, including illustrations, of a new species of mysid belonging to the genus Idiomysis W. M. Tattersall, 1922 from Pulau Bum Bum, Sabah, Malaysia. The presence of two segments of antennal scale, a shorter endopod of uropod than the exopod and a pair of minute spines at the apex of the telson distinguishes Idiomysis bumbumiensis sp. nov. from all other species in the genus. The present species is the seventh member of the genus Idiomysis and it is the first described in Southeast Asia. It is also the third species of tribe Anisomysini discovered in Malaysian waters. We include an updated dichotomous key of all Idiomysis species.
