Plectranthias  sp. 2

Figure 4 View Figure

A single specimen (90 mm TL) of an unidentified species of Plectranthias  was collected, photographed and preserved during the 2015 survey ( Figure 4 View Figure ) but subsequently lost during shipping to SAIABAbout SAIAB. The specimen was trawled on the 29 May 2015 off the Tanintharyi coast, Myanmar, Andaman Sea (10°2.91’ N, 97°22.78’ E) at a depth of 182 m. It was possible to determine some details from the photographs: dorsal rays X,14 (or 15?), fourth spine longest; dorsal fin not deeply notched between soft and spinous parts of fin; pectoral rays 14, rays unbranched (possibly branched at very tips of middle few rays?); caudal fin emarginate with upper rays produced; lateral-line complete with 29 scales; scales below lateral line to anal-fin origin ca 11; pelvic fins short, well short of anus. These details and the live coloration are similar to P. alcocki Bineesh, Akhilesh, Gopalakrishnan & Jena (2014)  , which was recently described from two specimens collected in the Arabian Sea off the south-west coast of India in 180– 320 m. However, the Myanmar specimen differs from the P. alcocki  type specimens in several live coloration details, most notably in lacking a large black spot on the operculum and a dusky spot ventrally on the abdomen. We therefore assume that it represents an undescribed species.
