Краткое описание
определительные ключи | морфология | морфометрия
членистые (мягкие) лучи спинного плавника (общее число) : 8 - 9; членистые (мягкие) лучи анального плавника: 22 - 25; позвонки: 34. This species is distinguished by the following characters: upper jaw with 2 rows of teeth; no scales on caudal-fin; incomplete lateral line; deep body, red in colour, with a black humeral and dorsal spot, anterior and posterior margined by a light zone. Also characteristic to this species are 6-10 conical to tricuspid teeth on the inner row of the premaxillary; 1-4 conical teeth on the outer row; 5-8 conical to tricuspid teeth on the maxillary; 8 gill rakers on dorsal limb, 13 on ventral; a black dorsal spot converges ventrally to a more or less rounded tip. H. werneri and H. epicharis have similar tooth pattern and a distinct black humeral spot; however, both have a long horizontally extended humeral spot and prolonged dorsal fins in males (vs. a round spot often with small expansions above and below and a short dorsal fin in the H. pando). H. pando differs in having a well developed infraorbital 4 vs. reduced to the laterosensory channel without dermal bones in H. werneri and, white tips of anterior rays of the pelvic and anal fins vs. coloured in H. epicharis (Ref. 82662).
Collected from a blackwater river with no aquatic plants, except for bladderwort Utricularia; pH 5.9 and conductivity of 15 μS/cm (Ref. 82662).
