Etymology: Lebiasina: Derived from Greek, lebias, lebiou = a kind of fish (Ref. 45335); minuta: The specific epithet minuta, meaning small, is in reference to the small size of adult specimens of Lebiasina minuta. Despite the large sample size of this species, no specimen
larger than 6.84 cm SL was collected and most specimens larger than 5.0 cm SL were mature. An adjective..

Short description
Identification keys | Morphology | Morphometrics
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) (Ref. 91748).
Facultative air-breathing in the genus (Ref. 126274)
