Raymunida vittata Macpherson, 2009: 446 , figure 7 (type locality: Vanuatu, SANTO 2006, stn DB16, 15.59°S, 167.26°E, 32–40 m depth); Osawa 2012: 140 , 143 (key), figures 3, 4(b); Poupin et al. 2022: 21, figure 9(f).

Material examined

India • 1 ♀ (PCL 9.0 mm, CW 7.7 mm); Andaman Sea, off Little Andaman Island ; FORVSS stn . 38806; 10.72°N, 92.7°E; 53 m depth; Chain dredge; 10 August 2019; Vinay P . Padate leg .; CMLRE IO /SS/ANO/00142.

Remarks

Morphological characters of the present specimen, including the carapace armature ( Figure 6 (a,)), the striations on thoracic sternites and pleonal tergites ( Figure 6 (c)), the relative lengths of spines on the antennal peduncle articles 1 and 2 ( Figure 6 (e)), and the armatures of Mxp3 ( Figure 6 (e)) and P3–4 ( Figure 6 (g–)), fall within the range of intraspecific variations of the type material from Vanuatu ( Macpherson 2009) and subsequently reported material from south-western Japan ( Osawa 2012).

Geographical distribution

Vanuatu ( Macpherson 2009), Ryukyu Islands, south-western Japan ( Osawa 2012), Mayotte Island, south-western Indian Ocean ( Poupin et al. 2022), Andaman Islands, India (present study); bathymetric range: 32–123 m depth ( Macpherson 2009; Osawa 2012). The present occurrence of R. vittata in the eastern Indian Ocean suggests that the species is widely distributed in the Indo-West Pacific although literature records are still scattered.
