Краткое описание
определительные ключи | морфология | морфометрия
членистые (мягкие) лучи спинного плавника (общее число) : 10; членистые (мягкие) лучи анального плавника: 9; позвонки: 54 - 56. Differs from all other Pangia except P. lumbriciformis by its unique color pattern consisting of a number of dark saddle-like marks on the dorsum, a dark transverse stripe or double spot at the caudal fin base and a horizontal stripe and a transverse subdistal band in the caudal fin, and by its total number of 54-56 vertebrae. Can be differentiated from P. lumbriciformis by a more robust body (body depth 10.8-13.8 times in SL vs. 13.6-15.4 times in SL, ratio body depth-body width 1.6-2.2 vs. 1.2-1.5) and a deeper and laterally more compressed caudal peduncle (ratio caudal peduncle depth/width 1.5-2.0 vs. 1.1-1.3). Among other Myanmar Pangia, it is distinguished further from P. fusca and P. pangia by a narrower (caudal peduncle depth 4.1-5.5 % SL vs. 5.9-9.7) and longer caudal peduncle (caudal peduncle length 14.4-16.0 % SL vs. 9.5-12.5), from P. pangia
by a more slender body (body depth 7.2-9.3 % SL vs. 13.5-16.3) and shorter pectoral fins (4.9-6.3 % SL vs. 8.2-9.6), from P. fusca by the presence of the pelvic girdle and fins (vs. absence) and the absence of a nasal barbel (vs. presence), and from P. elongata
by the position of the pelvic fins (basipterygia at vertebra 29 vs. 33) (Ref. 57993).
Facultative air-breathing in the genus (Ref. 126274); Found in stream with slow current, muddy gravel bottom with clear water but dark brown and with lots of algae and aquatic vegetation (Ref. 57993).

Estimates based on models
Phylogenetic diversity index (Ref.

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00525 (0.00241 - 0.01141), b=3.05 (2.87 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trophic level (Ref.
69278): 3.3 ±0.4 se; based on size and trophs of closest relatives
устойчивость к внешним воздействиям (Ref.
120179): высокий, минимальное время удвоения популяции до 15 месяцев (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
