title: A new species of Coleusia Galil, 2006 (Decapoda: Brachyura: Leucosiidae) from southern Asia.
abstract: A new species of leucosiid crab of the genus Coleusia Galil, 2006, is described from South and Southeast Asia. Coleusia huilianae n. sp. is distinguished from the superficially similar C. urania (Herbst, 1801) in the shape of the apical process of the first male gonopod which is digitate and curved laterally in the former (beak-like and curved interiorly in the latter); possessing smaller and sparser granulation on the posterior and lower margin of the cheliped and ambulatory meri; and the granulation is entirely missing from the lower external surface of the palm.
