Dorsale stekels (totaal) : 0; Dorsale zachte stralen (totaal) : 7; Anale zachte stralen: 19 - 20; Wervels: 45 - 46. Distinguished from other siluriform genera by having the following combination of characters: dorsal and ventral procurrent caudal-fin rays extended rostrally, dorsally reaching a vertical position on dorsal-fin base posterior to dorsal-fin insertion, ventrally continuous with anal fin; caudal fin round; all anal-fin rays unbranched; mouth prognathous, with jaws displaced dorsally on head; adductor mandibulae muscle hypertrophied, covering most of skull and inserting posteriorly onto first neural spine; first pectoral-fin ray soft, not spinous; bright red in life. Differs uniquely from its congeners by the absence of eyes, presence of 25-34 dorsal procurrent caudal fin rays; 14-16 ventral procurrent caudal fin rays; 45-46 vertebrae (Ref. 59347).

Occurs in artificial wells with transparent water, depth range 6 to 12 m and diameter of approximately 1 m (Ref. 59347). The water in the wells is used locally for human consumption. This fish is often mistaken for parasitic leeches " sanguijuelas" due to its bright, blood-red color and vermiform shape. For this reason, this is killed upon incidental capture when extracting drinking water from wells.

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.1 ±0.4 se; based on size and trophs of closest relatives

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