Two new species of the genus Chelidoperca (Perciformes: Serranidae) from the Andaman Sea, eastern Indian Ocean
Two new species of the genus <i>Chelidoperca</i> are described from specimens collected in 2015 and 2018 from the Andaman Sea, off the coast of Myanmar during trawl bottom surveys conducted by the R/V <i>Dr. Fridtjof Nansen</i>. <i>Chelidoperca myathantuni </i> s<b>p. nov. </b>is described based on 15 specimens (74.3–129.5 mm SL) from 101–185 m depth, which can be distinguished from all congeners by the following combination of characters: 3 (2 full-sized plus 1 half-sized) scale rows between lateral line and middle of spinous dorsal-fin base; 42–44 (modally 44) pored lateral-line scales; 16 pectoral-fin rays; interorbital scales extending to mid-orbit level; scales on ventral surface of lower jaw restricted to the angular (not extending onto the dentary); enlarged caniniform teeth on the upper jaw; side of body with longitudinal dashed black stripe; dorsal fin pale yellow with reddish pigment mostly restricted at base of spines and rays. <i>Chelidoperca flavimacula</i> s<b>p. nov.</b> is described based on eight specimens (49.7–70.7 mm SL) from 84–131 m depth, which can be distinguished from all congeners by the following combination of characters: 3 (2 full-sized plus 1 half-sized) scale rows between lateral line and middle of spinous dorsal-fin base; 42–45 (modally 42) pored lateral-line scales; 9–10 (modally 10) scale rows below the lateral line; 6 predorsal scales; 16–17 (modally 16) circumpeduncular scales; 5 scales rows on cheek; interorbital scales extending to mid-orbit level; anal fin with yellowish distal margin and three or four rows of bright yellow spots over its proximal half.
