Chiavi di identificazione | Morfologia | Morfometria
Raggi dorsali molli (totale) : 76 - 84; Raggi anali molli: 60 - 67; Vertebre: 42 - 45. This species is distinguished by the following characters: D 76-84; A 60-67; moderately large eyes (2.2-3.0%SL); slender body; rounded snout, no cirri; scales only cheeks; upper preopercular pore absent; outer pseudoclasper broad-based, large, sometimes beyond the hood when in resting position, with thickened tip especially on the inner face, while the inner one is large, thick, with posterior lobe folded over anterior pointed lobe; otolith length to height 2.1-2.3, with gently curved dorsal rim; otolith length to sulcus length 1.6-1.7, ostium length to caudal length 3.5-4.5; vertebrae 11-12 + 31-33 = 42-45 (Ref. 81230).
Body shape (shape guide): elongated; Cross section: compressed.
Found on volcanic rock boulders and sandy channels, shallow coral reef (Ref. 81230). Cryptic, solitary inhabitant of shallow water (Ref. 90102).
