Краткое описание определительные ключи | морфология | морфометрия

колючие лучи спинного плавника (общее число) : 1; колючие лучи анального плавника: 0. Diagnosis: gill slits not extending ventrally beyond pectoral-fin insertions; interorbital space less than 50% of head width (Ref. 57223), 89.3-102.3% snout length (Ref. 81251). Snout large and subrounded; lips moderately developed (Ref. 81251). Post-orbital length at least 60% of snout length; maxillary barbels longer than head, unbranched, without tubercles and bordered by a distinct, black basal membrane (Ref. 57223, 81251) at least as broad as barbel (Ref. 81251). Outer mandibular barbels with few short, spike-like ramifications, branches of inner mandibular barbels globose and bearing 2-3 tubercles; mandibular teeth thin and small, numbering 25-38 (Ref. 57223, 81251), movable, forming a transverse band (Ref. 81251). Entire margin of opercle smooth (Ref. 81251). Denticulations on outer margins of pectoral-fin spines relatively well developed on outer margin, but weaker than those on inner margin (Ref. 57223). Pelvic fin not reaching anal fin (Ref. 81251). Dorsal-fin spine smooth anteriorly, except for a few (4-5) apical denticles (Ref. 57223, 81251), none on posterior edge (Ref. 81251); humeral process triangular, rather deep (Ref. 57223), keeled ventrally (Ref. 57223, 81251) and sharply pointed (Ref. 81251). Adipose fin short (Ref. 57223, 81251), 1.1 to 3.4 times as long as its distance from first dorsal, and deep (base 2.1 to 4.7 times depth) (Ref. 81251), and distinctly separated from rayed dorsal fin (Ref. 57223). Anal fin with elongate anterior rays (Ref. 81251). Body covered with spots of about 1 mm in diameter; caudal fin spotted (Ref. 57223), without a single dark patch at base of each fin lobe (Ref. 81251). Caudal fin deeply forked, with upper lobes slightly longer; caudal peduncle as long as deep (Ref. 81251). Coloration: brownish, somewhat paler on belly; type not well preserved, but still has some black spots on adipose fin, possibly suggesting an also spotted body; other specimens have in fact body and head covered with spots; fins also spotted, the spots on caudal fin aligned as a band; maxillary barbels and their basal membranes black (Ref. 57223, 81251).

Maximum TL was recorded at 22.0 cm (Ref. 57223), maximum SL 16.8 (Ref. 81251). Oviparous (Ref. 205).

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=0.01479 (0.00896 - 0.02441), b=2.83 (2.69 - 2.97), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.9 ±0.3 se; based on size and trophs of closest relatives

устойчивость к внешним воздействиям (Ref. 120179): средний (среднего размера), минимальное время удвоения популяции 1.4-4.4 года (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (24 of 100).
