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).
Eponymy: Major Guillaume Clément Adolphe De Bauw (1865–1914) was a Belgian Army officer commissioned as a 2nd Lieutenant in the 2nd regiment of line infantry (1886). [...] (Ref. 128868), visit book page.

Environment: milieu / climate zone / depth range / distribution range
Ecology
Freshwater; demersal. Tropical; 3°N - 13°S
Africa: rivers Rembo Ngove and Nyanga in Gabon, Ogooué in Gabon and Republic of Congo, Kouilou in Republic of Congo, and Chiloango in Angola (Ref. 78218, 81643); also throughout the Congo River basin except for the Zambian Congo (Ref. 78218).
Length at first maturity / Size / Weight / Age
Maturity: Lm 6.5 range ? - ? cm
Max length : 12.6 cm SL male/unsexed; (Ref. 81643)
Dorsal spines (total): 1; Dorsal soft rays (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=0.00631 (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).
Trophic level (Ref.
69278): 3.3 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): Low, minimum population doubling time 4.5 - 14 years (Assuming fec < 100).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
