description

Description. Morphometric and meristic data for type specimens are provided in Table 1. Dorsal fin X, 15 (15 - 16), last soft ray branched to base; anal fin III, 9, last soft ray branched to base; pectoral-fin rays 14 (14 - 15); pelvic-fin rays I, 5; principal branched caudal rays 7 + 6 (7 + 6), upper procurrent and rudimentary unbranched caudal rays 9 (9), lower procurrent and rudimentary unbranched caudal rays 8 (8 - 9); pored lateral-line scales 34 (32 - 35); scale rows above lateral line to origin of dorsal fin 3; scale rows below lateral line to origin of anal fin 10 (9 - 10); gill rakers on upper limb 8, on lower limb 22; vertebrae 27 (10 precaudal + 17 caudal). Body slender, compressed, its greatest depth 3.18 (2.96 - 3.13) in SL, the width just posterior to gill opening, 1.89 (1.77 - 2.09) in depth; head length 2.79 (2.88 - 3.52) in SL; snout short, its length 6.08 (4.88 - 7.12) in head; orbit diameter 3.34 (2.48 - 3.32) in head; interorbital convex, the least bony width 3.94 (2.78 - 4.03) in head; caudal peduncle depth 3.21 (2.33 - 3.56) in head. Mouth large and oblique; lower jaw not projecting beyond the upper when mouth closed; maxilla 2.15 (1.96 - 2.16) in head, diagon

diagnosis

Diagnosis. The new species differs from all other Anthiadinae by the following combination of characters: Dorsal-fin spines X; last dorsal spine the longest, 1.8 - 2.2 in head length; dorsal-fin rays 15 - 16; 7 th dorsal ray the longest, 2.65 - 2.80 in head length; anal-fin rays 9; pored lateral-line scales 32 - 35; ventral scale rows 9 - 10; body slender and compressed, greatest depth 2.96 - 3.18 in SL, and the width 1.77 - 2.09 in depth. Our phylogenetic analysis shows the new species belongs to Tosanoides Kamohara 1953, from which it differs of the other known species by: a divergence of at least 12.35 % at the cytochrome oxidase I gene, last dorsal spine the longest (instead first through fourth), fewer dorsal-fin rays (15 - 16 vs. 16 - 17), and more anal-fin rays (9 vs. 8 in the other Tosanoides).
