Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 7 - 8; Dorsal soft rays (total): 7 - 8; Anal spines: 1; Anal soft rays: 7 - 8; Vertebrae: 26. This species is distinguished by the following characcters: pectoral fin 14-16 rays (usually 15 rays); nape and posterior part of occipital region with cycloid scales and the scaled area extending anteriorly to around a vertical line through posterior margin of preopercle or a little posterior to this line; longitudinal scales 27-31, predorsal scales 3-11; total vertebrae 26; cephalic sensory pore system usually with B´, C, D(S), E, F, H´, K´, L´, M´, N, and O´, but often lacking one or both side(s) of pore E; cheek with transverse rows of sensory papillae. Colouration: when preserved, lateral and dorsal sides of the body with dark brown mesh-like markings, snout and cheek with three dark brown stripes, and pectoral fin with dark brown band vertically across proximal part of the upper and middle rays except lower 2-6 rays; when fresh, upper and middle parts of pectoral-fin base with bright white vertical band (Ref. 125663).
Water temperature of collection sites Estrella Falls was cool even during the hottest dry season (water temperature was 26.5°C, 13 May, 2016), while water in the Malatgao River was warmer (estimated to be nearly 30°C) (Ref. 125663).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00724 (0.00338 - 0.01553), b=3.05 (2.87 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-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).
