ຄີຫຼັງຂອງປາ (ຄີອ່ອນ) (ທັງໝົດ): 8-9; ຄີກົ້ນຂອງປາ: 19 - 22. This species is distinguished by the following characters: D ii + 8; pelvic-fin rays i + 5; teeth in the inner series of the premaxilla 4; differs from all species of the Stevardiinae by having a single conical tooth in the outer premaxillary series (vs. absent); lacks a pheromone pump usually associated with modified scales on the caudal-fin base; eye large; a line of black chromatophores along the bases of anal and caudal fins; body transparent with abdominal region iridescent blue in life (Ref. 93233).
Specimens were caught with a seine pulled at approximately 1.5 m depth. The type locality is a beach on a rocky poorly vegetated plateau, where the water was dark black with slow current. Individuals were collected at night, approximately between 20:00 and 24:00, during the dry season (October). Stomach contents of cleared and stained specimens were mainly remnants of insect larvae (Ref. 93233).
