A new species of Tritodynamia (Brachyura, Macrophthalmidae) from Papua, Indonesia

Tritodynamia nontjii n. sp. is described from Papua, Indonesia, and is distinguished from
congeners by its proportionately broader carapace and relatively shorter ambulatory legs. The new
species superficially resembles T. yeoi Naruse & Ng, 2010, from Singapore, in having the male first
gonopod stout with the distal portion broad and curved, but the two species differ in the proportion
of the carapace and structures of the ambulatory legs. A table of morphological differences of all
known species of Tritodynamia is also provided to distinguish the taxa.
