On two new species of the genera Haberma and Parasesarma (Crustacea: Decapoda: Brachyura: Sesarmidae) from Papua, Indonesia

Two new species of sesarmid crabs are described from the mangroves of Timika in Papua (= Irian Jaya), Indonesia. Haberma kamora spec. nov. is the second species in the genus described from Singapore, differing from the type species in the form of its male first pleopods and possessing relatively more slender ambulatory legs. Parasesarma charis spec. nov. resembles P. erythrodactyla, P. tripectinis and to some extent, P. lepidum, but has different ambulatory leg proportions and a distinctive male first pleopod structure. Parasesarma acis Davie, 1993, is regarded as a junior synonym of P. tripectinis Shen, 1940.
