Abstract
Two new species of karst sesarmid crabs of the genus Karstarma Davie & Ng, 2007, are described from western Papua, Indonesia. Karstarma ardea n. sp. differs from the allied K. ultrapes (Ng, Guinot & Iliffe, 1994) from the Solomon Islands by its proportionately shorter ambulatory legs and the shape of its vulva. Karstarma waigeo n. sp. is closest to K. balicum (Ng, 2002) from Bali, Indonesia, but differs in its proportionately longer ambulatory legs and in the morphology of the male first gonopod.

Key words: Crustacea, Decapoda, Brachyura, Sesarmidae, Karstarma, new species, Indonesia
