Two new distributional records of Palaemonella Dana, 1852 shrimps (Decapoda: Caridea: Palaemonidae) from Lakshadweep Islands, India

Abstract

Abstract The present study reports two new distributional records of palaemonid shrimp, Palaemonella tenuipes Dana, 1852, and P. rotumana (Borradaile, 1898) from the Lakshadweep region, Arabian Sea. The study provides detailed information on, and insight into, diagnostic characters, distinctiveness, and illustrations of both species. The individuals of P. tenuipes were collected from a depth of about 0.5 m in shallow barren pools on rocky flats near the shore, while a specimen of P. rotumana was collected from a dead coral patch at a depth of 1-2 m. The intraspecific genetic divergences were estimated for both species using COI and 16S sequence data.
