Краткое описание
определительные ключи | морфология | морфометрия
членистые (мягкие) лучи спинного плавника (общее число) : 6 - 8; членистые (мягкие) лучи анального плавника: 9. Body uniformly dark-brown. Interopercle with 3 rows of odontodes; posterior region of interopercle close to anterior margin of pectoral fin; interopercular patch of odontodes long (38-48% HL). Upper lip wide with margin of mouth distant from tip of snout. Adipose fin small, emerging gradually posterior to dorsal fin. Prepelvic (49-52% SL) and predorsal (50-55% SL) long. Head wide 94-103% HL). Orbital rim free. Eyes large, about 8 times in HL. Caudal fin bilobed. Maxillary and nasal barbels not reaching posterior margin of pectoral fin and rictal barbel not extending beyond half length of interopercle. Outer row premaxillary and dentary teeth overlapping distally; dentary teeth not extending to coronoid process of lower jaw; dentary teeth inclined relative to surface of dentary bone. Lower lip split in 2 bilateral halves by median constriction (Ref. 45131).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 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).
Trophic level (Ref.
69278): 3.2 ±0.4 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
