Etymology: Lepthoplosternum: Greek, leptos = thin + Greek, hoplon = weapon + Greek, sternon = chest, sternum (Ref. 45335); ucamara: Named for the U.S. National Sciences Foundation funded Project Ucamara and also for the geological term Ucamara depression describing the low-lying reaches of the Ecayali and Marañon rivers caused by the subsidence in the Upper Amazon foreland basin. More on authors: Reis & Kaefer.

Morphology | Morphometrics
Diagnosis: Lower lip with short, rounded projections lateral to the medial notch. Caudal peduncle is comparatively shallow (15.2-17.7% SL). Dorsal fin with 2 unbranched and 6 branched rays. Head depth small 19.9-21.8% SL; short first dorsal-fin ray 13.7-17.5% SL; maxillary barbels reaching lower lateral series plate 13-15 (Ref. 56211).
Collected in lakes or lake channels within dense marginal or floating vegetation, sometimes in hypoxic conditions (Ref. 56211).

Phylogenetic diversity index (Ref. 82805
= 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.0 ±0.3 se; Based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
