Description synthétique Clés d'identification | Morphologie | Morphométrie

Rayons mous dorsaux (Total) : 7 - 10; Rayons mous anaux: 5 - 8; Vertèbres: 37 - 38. Differs from all its congeners by the following combination of characters: body completely scaled with well developed eyes; lateral line curved possessing 57-64 scales; pectoral fin not reaching the origin of the pelvic fin and the last unbranched ray of the dorsal fin clearly serrated along its posterior edge; 8-9 predorsal vertebrae; 8-9 gill rakers; joints of dentary-angulars not close to each other at the isthmus; and a slightly inferior mouth with the upper jaw (6.2-7.4% SL) protruding slightly beyond the lower one (5.7-6.7% SL) (Ref. 57607).

Inhabits subterranean river with water surface about 10-20 m inside the mouth of a small cave located about 50-100 m up from the bottom of a 4 square km lowland depression in a mountainous region (Ref. 57607). The subterranean water flows out during the flood season, making the lowland depression looks like a small lake (Ref. 57607).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01122 (0.00521 - 0.02417), b=3.02 (2.85 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 2.9 ±0.3 se; based on size and trophs of closest relatives

Résilience (Ref. 120179): Haut, temps minimum de doublement de population inférieur à 15 mois (Preliminary K or Fecundity.).

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