On a new species of tree-climbing crab of the genus Labuanium (Crustacea: Decapoda: Brachyura: Sesarmidae) from Taiwan

摘要

Specimens of a tree-climbing sesarmid crab from Taiwan previously referred to Labuanium rotundatum (Hess, 1865) are here shown to belong to a new species, L. scandens. The new species differs from L. rotundatum s. s. in having a less prominently granulated carapace, the outer surface of the chela covered with numerous small and closely arranged granules, and a differently structured male first pleopod.
