Paraleptuca crassipes is easily recognised in the field by the red colouration on the dorsal surface of the carapace, chelipeds, and legs. The morphological characteristics of our samples fit the descriptions by Crane (1975) , Shih et al. (2012) and Shih et al. (2016) . The G1 of our samples from Liki Island ( Fig. 5H–I ) resembles that of Crane’s (1975 : fig. 13G) specimens from Hong Kong , in which the apical portion is distinctly long and the flange is distinctly short. Shih et al. (2012) reported that P. crassipes is widely distributed in the western and central Pacific Ocean and the eastern margin of the Pacific region. The present record extends the distribution of this species further eastward within the Indonesian Archipelago. This species inhabits muddy substrates on the intertidal area.
