توصيف مختصر
كليدهاي شناسايي | ريخت شناسي | ريخت ستجي بوسيله انداره گيري
شعاع نرم باله پشتي (کل) : 10 - 11; شعاع نرم باله مخرجي: 25 - 29; مهره ها: 40. Bryconops tocantinensis is distinguished from all species of Bryconops, except
B. humeralis and B. vibex by the color pattern in vivo (dorsal, adipose, and caudal fins entirely orange). It differs from B. humeralis and B. vibex by the lack of a humeral spot and by the lack of maxillary teeth (vs. a single humeral spot present and 1-3 maxillary teeth on both sides present). It can be further diagnosed from B. vibex by having 38-41 perforated lateral line scales (vs. 44-46) (Ref. 109891).
Inhabits stream and lotic shallow areas (depth up to 1.5 m) with riparian vegetation composed by trees and shrubs. The stream is characterized by transparent water and sandy, stony, and rocky bottom. Occurs syntopically with Eigenmannia trilineata, Hoplerythrinus unitaeniatus,
Astyanax cf. goyacensis, Knodus cf. breviceps, Knodus sp., and Ancistrus sp. (Ref. 109891).
