RAFFLES BULLETIN OF ZOOLOGY 2022

Colour in life. Shield mottled light green and brown. Ocular peduncles reddish orange, each with bluish white band at base of corneas, tinge of dark brown proximally. Chelipeds brownish black with yellowish spines and tubercles. P2 and P3 brown or brownish black, each with broad light orange or tannish orange stripe on lateral face extending from base of claw to proximal margin of merus.

Distribution. Indonesia, Vietnam, Tahiti, and now Singapore; intertidal, on sandy mud and gravel substrates.

Remarks. Rahayu (1996) included Singapore in the distributional range of this species by mistake as she examined only a specimen from Batam, Indonesia ( Rahayu, 1996: 352, table 1). This is the first confirmed record of C. ransoni from Singapore, represented only by one specimen.
