Short description
Chiavi di identificazione | Morfologia | Morfometria
Raggi dorsali molli (totale) : 5 - 6. This species is distinguished by the following characters:flattened body disk, with anterior portion of skull only slightly elevated above other part of disk; small rostrum, very short rostral spine, its length 3.9%-7.6% SL, and directed obliquely to upward vertically; bucklers on body uniformly flattened without sharp apices; large naked areas on central region of dorsal disk; ventral surface of disk partly covered with large bucklers on the thoracic region and smaller bucklers on belly; thoracic region and gill cavity are naked; subopercular buckler
with an enlarged, anteriorly directed spine bearing spinelets along its margin; small orbit, its diameter x? = 12.2% SL); interorbital space broad (x? = 7.3%) SL; rostrum short (x? = 5.5%) SL; OD/IO = 1.3-2.0; OD/RL = 1.6-2.9; the anal fin does not reaching caudal-fin base when appressed; D 5-6; pectoral-fin rays 11-13 (Ref. 123774).

Trophic level (Ref.
69278): 3.3 ±0.5 se; based on size and trophs of closest relatives
Resilienza (Ref.
