Rayons mous anaux: 22 - 24. This species is distinguished by the following set of characters: D IV- V +I,12-14; A I, 22-24; 36-37 lateral scales; 10 transverse scales; 17-19 anterior scales; 12-15 cheek scales; GR 17-18 on first arch; pointed head with a long snout length, 9.1-9.7% of SL; intermediate interorbital width, 8.4-8.8% of SL; compressed body with a long anterior back length, 51.1-53.2% of SL; large caudal peduncle depth, 10.7-11.6% of SL; long pectoral fin length, 20.2-21.9% of SL; moderately short dorsal fin base length, 32.9-38.5; dorsal fin base protruding vertically behind anal origin, between 3rd and 5th anal soft ray. Colouration: distinct red margin stripe on second dorsal fin (Ref. 103156).

Found only in the type locality, with depth to about 4 m, with moderate to fast flowing clear water over a limestone rocky substrate. Maximum length based on type specimen, to be replaced with a better reference (Ref. 103156).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 2.9 ±0.4 se; based on size and trophs of closest relatives

Résilience (Ref. 120179): Milieu, temps minimum de doublement de population : 1,4 à 4,4 années (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
