Short description
Identification keys | Morphology | Morphometrics
Dorsal soft rays (total): 15 - 25; Anal soft rays: 18 - 24; Vertebrae: 29 - 31. Caudal peduncle of female with black spots. Male's anal fin with gray to black distal stripe, iridescent dots restricted to posterior portion of the fin, anterior part pink and posterior yellow; basihyal broad, 70-95% in length; and, second pharyngobranchial teeth,5-10. Dorsal-fin rays 22-25 in male, 15-19 in female; anal-fin rays 22-24 in male, 18-22 in female; caudal-fin rays 23-25, caudal fin subtruncate in male, rounded in female. Males possess pronounced pectoral-fin contact organs and elongated brilliant spots on anterobasal part of dorsal fin (Ref. 49550).
Occurs in seasonal pools (Ref. 89836).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.2 ±0.4 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.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
