WA Museum Records and Supplements | Updated 8 years ago

ABSTRACT – Lymnastis brooksi sp. nov. is described from a cave on Christmas Island in the northern Indian Ocean. The sole specimen is depigmented and completely eyeless and moreover is easily distinguished from other species of the genus Lymnastis Motschulsky by the large pronotum bearing remarkably acute and projected basal angles, by the almost non-serrate margins of the elytra, and by their very inconspicuous striation. The relationships of the new species so far arc unsettled. A preliminary key to the species of Lymnastis recorded from the Oriental, Papuan and Australian regions is provided.
