определительные ключи | морфология | морфометрия
колючие лучи спинного плавника (общее число) : 0; членистые (мягкие) лучи спинного плавника (общее число) : 70 - 76; колючие лучи анального плавника: 0; членистые (мягкие) лучи анального плавника: 55 - 61; позвонки: 39 - 41. Diagnosis: This species is characterized by the following: vertebrae 11+28-30=39-41, dorsal fin rays 70-76, anal fin rays 55-61; eyes very small (<2.0% SL); outer pseudoclasper ear-lobe shaped, the half-moon shaped ear-lobe extension inwardly directed; inner pseudoclasper firmly joined to outer pseudoclasper anteriorly, with supporter, reduced small hook-like, often with a fleshy flap at its base; 5-7 rows of small scales on the upper cheek, no scales on operculum; head profile is slender; otolith length to height ratio <2.0 (Ref. 57884).
Rare species (Ref. 34024). Solitary inhabitant of coral reef crevices to at least 15m depth, cryptic (Ref 90102).
