Etymology: Pareutropius: Greek, par = beside, near + Greek, eu = well + Greek, tropis = keel, in reference to the compressed body of the fish; debauwi: Named for Mr. De Bauw, collector of the type material of this species (Ref. 43912).

背棘 (总数) : 1; 背的软条 (总数) : 4 - 6. Diagnosis: single pair of mandibular barbels; 4-5 (exceptionally 6) branched dorsal fin rays; 30-54 branched anal fin rays; no dark oblique band (from posterior border of operculum to above anus), no dark spots on caudal lobes, dorsal dark band continues onto caudal fin (Ref. 43912, 81643). 7-8 (rarely 9) branchiostegal rays on one side of head; base of anal fin marked by small dark line (Ref. 43912).
Riverine species with gregarious habits, confined to large as well as moderate and small water systems (Ref. 43912). Forms schools (Ref. 6868). Carnivorous with insectivorous preference; reproduction probably coincides mainly with flood periods (Ref. 43912). Oviparous, eggs are unguarded (Ref. 205). Maximum total length recorded 148 mm (Ref. 43912, 81643).
群游鱼。 (参考文献 6868)

50 = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00631 (0.00205 - 0.01941), b=3.16 (2.91 - 3.41), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
营养阶层 (Ref.
