Descripción breve
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 7; Radios blandos dorsales (total) : 8; Espinas anales: 1; Radios blandos anales: 7. This species is distinguished from all its congeners by the following set of characters: with a complete cephalic sensory-canal pore system (pattern 1); dorsal/anal fin-ray formula 8/7; some pectoral-fin rays are branched; presence of a fifth pelvic-fin ray; absence of dark occipital spots or any dark spots at the base of dorsal or caudal fins; with a broad and fringed male urogenital papilla; entire body and fins purplish black (Ref. 137777).
Body shape (shape guide): fusiform / normal; Cross section: oval.
A single specimen was collected from 4 m depth on the reef crest, from a small burrow in the top of a large Porites coral bommie, and this reef crest has many large Porites and other massive corals, transitioning into branching and foliose corals occupying the reef slope at a 45° angle to a maximum depth of 40-50 m (Ref. 137777).
