Max length : 4.2 cm SL male/unsexed; (Ref. 55975)

(total): 1;
Vertebrae: 34 - 35. Distinguished from all congeners in having highly elevated supraoccipital spine and nuchal plate. Differs further from congeners in having a unique combination of the following characters: highly contrasting light brown patches on a chocolate brown body; lack of filamentous extensions to the first pectoral-fin element; presence of 5-6 serrations on the posterior edge of pectoral spine; eye diameter 6-9% of head length; branchiostegal membranes meeting at isthmus ventrally; outer mandibular barbels reaching middle of pectoral-fin base; and rounded tubercles on the tip of the snout and dorsal surface of neurocranium (Ref. 55975).

Estimates of some properties based on models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5001 [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), based on all LWR estimates for this body shape (Ref.
93245).
Trophic Level (Ref.
69278): 3.5 ±0.6 se; Based on size and trophs of closest relatives
Resilience (Ref.
69278): High, minimum population doubling time less than 15 months ().
Vulnerability (Ref.
59153): Low vulnerability (10 of 100) .
