簡短描述
檢索表 | 型態特徵 | 形態測量圖
This species lacks preopercular canal and associated pores of cephalic sensory systems as with Eviota lacrimae and E. sparsa, but differs from these two in having moderately developed fifth pelvic-fin ray (10.5-18.1% of preceding ray in length) and a distinct semi-ocellated spot at the anteroventral part of first dorsal fin (Ref. 81713).
Body shape (shape guide): fusiform / normal.
Found resting only on the substrate at the mouth of a river in an estuary (Ref. 116739).
