Etymology: Atherinomorus: Greek, atherina, the Greek name for the eperlane + Greek, moros = silly, stupid (Ref. 45335). More on authors: Jordan & Evermann.

Maturity: Lm ?  range ? - ? cm
Max length : 9.8 cm FL male/unsexed; (Ref. 111300); max. published weight: 9.00 g (Ref. 111300)
(total): 6 - 8;
soft rays: 15 - 18. Slender fish with moderately laterally compressed body. Teeth on vomer very small and difficult to see. Gill rakers with spinules longer than diameter of pupil. Predorsal scales 20-23.
