Etymology: Microglanis: Greek, mikros = small + Greek, glanis = a fish that can eat the bait without touching the hook; a cat fish (Ref. 45335); pataxo: Named in honor of Pataxó native indigenous people, who live in the neighborhoods of the distribution area of this new species.
Eponymy: The Pataxó are an indigenous people of northeastern Brazil. They live in areas where these species occur. (Ref. 128868), visit book page.

Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 7; Vertebrae: 29. Distinguished by the color pattern with a dark blotch beneath adipose fin not extending to anal fin and by the high number of anal fin proximal radials, 12, shaped as rod-like thin tubes, the last one bearing a laminar extension. Can be diagnosed by the following combination of characters: a pectoral fin spine with a bony point and bearing proportionally few serrations on posterior border of pectoral fin spine, eight to ten; seven pleural ribs and a proportionally short head width (67.8-74.3% in HL).

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=0.00741 (0.00314 - 0.01747), b=3.10 (2.90 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.4 se; based on size and trophs of closest relatives

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