ຄີຫຼັງຂອງປາ (ຄີອ່ອນ) (ທັງໝົດ) : 7; ຄີກົ້ນຂອງປາ: 6. Metamorphosed females distinguished by the following characteristics: length of illicium less than 120% SL; distal escal prolongation with spinules at base and several unpigmented, digitiform filaments on lateral margins; absence of escal papillae; posteromedial papilla at base of escal bulb and second on illicium below bulb; absence of proximal escal filaments; dentary teeth relatively long (longest 2.6-5.2% SL), in four or five longitudinal series; rays of caudal fin less than 30% SL (Ref. 86949).
Minimum depth from Ref. 58018.
