A new species of the pontoniinid shrimp genus Periclimenes, P. sarasvati, is described on the basis of five female specimens associated with anthozoan invertebrates from the Ryukyu Islands, southern Japan. The new species is a member of the 'P. aesopius species group', and is closely similar to P. venustus. Morphologically, it differs from P. venustus by having a smaller 'bec ocellaire' of the ophthalmic somite, 3 minute distomesial teeth on the incisor process of the mandible, the bilobed distal endite of the maxilla, the shorter second pereiopod, and the smaller number of recurved teeth on the cutting borders of the second pereiopodal chela. Keys to the known species of the species group (both morphology and coloration) are provided.
