Maturity: Lm ?  range ? - ? cm
Max length : 2.2 cm SL male/unsexed; (Ref. 76852); 3.4 cm SL (female)

Short description Morphology | Morphometrics

Dorsal soft rays (total): 7-9; Anal soft rays: 9 - 11; Vertebrae: 31 - 32. Distinguished by the following uniquely derived autapomorphies: presence of a rounded spot located on the lower half of the caudal peduncle close to the base of lowest caudal-fin rays; a patch of dark pigmentation on the last anal-fin rays of females; halves of gonopodial paired appendix straight and perpendicular to R3. Differs further from its congeners by gonapophysis of vertebra 14 straight in adult males; and anterior orbital bone present (Ref. 76852).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00676 (0.00289 - 0.01579), b=3.13 (2.94 - 3.32), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.0   ±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 (13 of 100) .
