Etymology: Pareutropius: Greek, par = beside, near + Greek, eu = well + Greek, tropis = keel, in reference to the compressed body of the fish; debauwi: From the Latin "vittatus" (covered with stripes), referring to the colour pattern of the species (Ref. 43912).

Description synthétique
Morphologie | Morphométrie
Épines dorsales (Total): 1; Rayons mous dorsaux (Total): 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).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref.

Niveau trophique (Ref.
69278): 3.3 ±0.5 se; based on size and trophs of closest relatives
Résilience (Ref.
120179): Faible, temps minimum de doublement de population : 4,5 à 14 années (Assuming fec < 100).
Fishing Vulnerability (Ref.
