🔬 Taxonomy

🐟 Physical Description

Dorsal soft rays (total): 10; Anal soft rays: 11 - 12. Can be easily diagnosed from all lebiasinins, except Lebiasina melanoguttata, by the following characters: absence of the primary and secondary stripes, as well as the caudal blotch; the presence of three longitudinal series of dark blotches at the base of the scales; the pair of foramina on the vomer through which the ramus palatinus of the facial nerve passes; the large laminar extrascapular bone in contact with the fifth infraorbital and overlaying the anterodorsal portion of the opercle; and the nearly equal caudal-fin lobes. Differs from Lebiasina melanoguttata in the presence of a dark blotch at the base of the middle dorsal-fin rays, the second infrapharyngobranchial being edentulous, the yellowish overall coloration of the body, the dark olive green eyes, and the dark blotches of longitudinal series 3 and 4 coalescing where scales of adjacent longitudinal series overlap (vs. dark blotch absent; second infrapharyngobranchial with conical teeth; the reddish overall color of body and eyes; and the dark blotches of longitudinal series not coalescing) .: elongated.
