背棘 (总数) : 10; 背的软条 (总数) : 15 - 16; 臀棘: 3; 臀鳍软条: 9; 脊椎骨: 27. This species is distinguished from its congeners by the following set of characters: D X, 15-16 with last dorsal spine the longest, 1.8-2.2 in head length and the 7th dorsal ray the longest, 2.65-2.80 in head length; A 9; pored lateral-line scales 32-35; ventral scale rows 9-10; body is slender and compressed, with greatest depth 2.96-3.18 in SL, width 1.77-2.09 in depth. Phylogenetic analysis shows the new species belongs to Tosanoides and 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) (Ref. 120716)
Found on mesophotic coral ecosystems of the island and observed while rebreather diving. A single observation at 260 m depth was taken from a submersible dive. It inhabits small crevices of complex rocky reefs. Ambient seawater temperature at the collecting depth (ca. 120 m) varied between 13 and 15 °C during the two-week observation period (Ref. 120716).
