soft rays: 11;
Vertebrae: 26. Lower jaw sharply upturned, nearly perpendicular to body axis; teeth conical rather than tricuspid as in all Lebias species except L. asquamatus; cephalic neuromast system open, not in closed canals as in the L. dispar and L. fasciatus groups; interarcual cartilage absent versus present in all congeners except L. asquamatus; pectoral fins obliquely set rather than horizontal as in all congeners; large size, approaching 9.1 cm TL versus maximum body size of 7.0 cm TL for congeners (Ref. 39284).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00933 (0.00405 - 0.02151), b=3.23 (3.05 - 3.41), based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 2.9 ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (20 of 100) .
