Periclimenes bicolor Edmondson, 1935: 10 , fig. 3

Material examined. 3 individuals (2 ovigerous female and a subadult male (tl 7–11 mm, cl 1.3–1.5 mm), Agatti Island, Lakshadweep, rocky intertidal and lagoon, on cushion star Culcita sp. depth 3 m.

Diagnosis based on the collected material. Rostrum has twelve dorsal teeth; proximal segment of antennular peduncle bears a disto-lateral teeth, mandible is slender and incisor with strong disto-lateral tooth. Fingers of the chela of first pereiopods are strong with denticulate cutting edges, dactylus are more slender and acute, second pereiopods showed considerable variation in size which is unequal and irregular, bears a acute tooth on the dactylus. Third pereiopods show a distinct acute ventral tooth, fourth and fifth pereiopods the datylus tooth is weakly acute and carpus of the dactylus possess a pair of medial setae and distinctly unguiculated.

Habitat. Our specimens were collected from the rocky intertidal as well as from the lagoon area at a depth of 3m.

Host. P. s o ro r is primarily an associate of Oreastearid starfish and the detailed associations of hosts were discussed in detail by Bruce (1978). Our specimens were associated with the cushion sea star Culcita sp.

Distribution. In India, the species has been considered as the first report. Further notes on detailed distribution were provided by Bruce (1978).

Remarks. Reported for the first time in Agatti Island, Lakshadweep, India. Previous photographic evidence of the specimen was provided by Apte (2012), but the species name and locality was not mentioned.
