Morphology | Morphometrics
Vertebrae: 30 - 32. Diagnosis: body relatively elongate; abdomen not greatly expanded, more or less extensively darkly pigmented; sucker very large, longer than broad (not transversely oval), extensively covered with moderately large papillae; mandibular barbels short but well-developed, usually papillose, with up to 3 auxiliary mandibular barbels on each side of lower lip; large premaxillary teeth in 3-4 rows; mandibular teeth large, usually 4+4 or 5+5 (but some with 7+7 or 8+8); eyes large; adipose fin long, its origin considerably in advance of a vertical through anal fin origin; caudal peduncle moderately slender to very slender; caudal fin not deeply forked with lobes rounded or even truncate, lower slightly longer than upper (Ref. 81251).
Coloration: body with dark bands fairly distinct; abdomen more or less darkly pigmented, almost black in some specimens (Ref. 81251).
Oviparous (Ref. 205). Maximum total length reported is 5.5 cm (Ref. 3202).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.1 ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
