Metasesarma obesum (Dana, 1851)

Material examined. 1 male (9.2 x 8.4 mm) (DABFUK), Kavaratti, 10 October 2014 .

Remarks. This is a common supralittoral species widely distributed in the Indo-West Pacific. The species was also seen at Kalpeni but specimens were not collected. Previously recorded from Lakshadweep (Alcock 1900b; Dev Roy 2008; Kumaralingam et al. 2017). The species is better known as Metasesarma rousseauxi H. Milne Edwards, 1853, but Ng & Schubart (2003) showed that Sesarma obesa Dana, 1851, is a senior subjective synonym.
