Brackish intertidal, river mouths, fringing mangroves, and nipa palms, on sandy, rocky, and sand-mud substrates. Remarks. Rahayu (2003) noted that Cl. longitarsus has very variable colouration, however the longitudinal blue stripe on the lateral face of ambulatory legs, a specific character of this species, is always present, even after long periods of preservation in alcohol. This species is reported for the first time in the Philippines .
