Pseudanthias emma new species Figure 1; Tables 1–2 Emma’s basslet Holotype. SAIAB 203722, 107 mm SL, off Tanintharyi coast, Myanmar, Andaman Sea, Indian Ocean (11°39.96’ N, 97°16.16’E), 105 m, R/ V Dr. Fridtjof Nansen , stn 149, bottom trawl, 25 May 2015, collected by P. N. Psomadakis. Diagnosis. The following combination of characters distinguishes Pseudanthias emma from congeners: dorsal rays X,16; pectoral rays 18; lateral-line scales 42; third dorsal-fin spine longest, prolonged; no papillae on posterior margin of orbit; soft part of dorsal with low scaly sheath; subopercle and interopercle indistinctly serrated; caudal fin weakly concave centrally, with elongate filaments extending from second to uppermost and second to lowermost branched rays. Description. Dorsal rays X,16, all segmented rays branched; third dorsal-fin spine longest, with fleshy pennant extending from tip; anal rays III,7, all segmented rays branched; pectoral rays 18/18, all rays branched except upper 2/2, no serrations on rays; pelvic rays 1,5; caudal fin weakly concave centrally, with elongate filaments extending from second to uppermost and second to lowermost branched rays; principal caudal rays 9 + 8; branched caudal-fin rays 7 + 6; upper procurrent caudal-fin rays 7; lower procurrent caudal rays 7; lateral-line scales 42/42; scales above lateral-line to origin of dorsal fin (counted upwards and forwards from lateral line) 6/6; scales above lateral-line to base of fifth dorsal spine (counted upwards and forwards from lateral line) 4/3; scales above origin of anal fin origin to lateral line (counted upwards and forwards from anal origin) 18/18; circumpeduncular scales 26; gill rakers 11 + 22; branchiostegal rays 7; pseudobranch filaments 20. Vertebrae 10 + 16; predorsal formula 0/0+0/2/1+1; main shaft (proximal component) of first dorsal pterygiophore roughly perpendicular to long axis of body; no trisegmental pterygiophores associated with dorsal and anal fins; ribs present on vertebrae 3 through 10; epineurals present on vertebrae 1 ...
