Краткое описание
определительные ключи | морфология | морфометрия
членистые (мягкие) лучи спинного плавника (общее число) : 9; членистые (мягкие) лучи анального плавника: 18 - 20; позвонки: 33 - 34. This species is distinguished from other members of its species group by the following characters: 5-6 pored lateral-line scales (vs. 7-23), conical maxillary teeth (vs. maxillary teeth tri- or multicuspid); 5 infraorbitals (vs. 6 except in H. heterorhabdus and H. amaronensis with 5); mean body depth 29.65 % SL (vs. 35.71-42.12%; except in H. heterorhabdus with mean body depth 30.39 and H. diancistrus with 23.70); mean upper jaw length 18.94% SL (vs. 22.70-30.51%; except H. amaronensis with 15.66%); presence of a red band above the dark lateral band (vs. without band); males with hooks on all fins (vs. spines not on all fins) (Ref. 84248).
Found over organic detritus and decomposing vegetation, apparent water color was brown to black, low dissolved oxygen (0.42-0.75 mg/l), as was conductivity (42-43 μs) and oxygen saturation (5.3-10 %), slightly acidic pH (6.0-6.2). Two of the five stomachs of cleared and stained specimens contain insects (100 %N, 85. 71%V) and unidentified digested material (14.28%V) (Ref. 84248).

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01259 (0.00520 - 0.03049), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 2.9 ±0.3 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref.
