Actinopteri (ray-finned fishes) > Siluriformes
(Catfishes) > Schilbeidae
Etymology: Pareutropius: Greek, par = beside, near + Greek, eu = well + Greek, tropis = keel, in reference to the compressed body of the fish; longifilis: From the Latin "longus" (long) and "filum" (filament), referring to the long barbels of this species (Ref. 43912). More on author: Steindachner.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; demersal. Tropical; 23°C - 27°C (Ref. 12468); 8°S - 16°S
Africa: Ruvu, Rufiji-Great Ruaha and Ruvuma systems in Tanzania, and lakes Chiuta and Chilwa in Mozambique and Malawi (Ref. 43912).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 9.2 cm SL male/unsexed; (Ref. 43912)
soft rays: 50. Diagnosis: two pairs of mandibular barbels; adipose fin small; dorsal fin with only 3-4 soft branched rays; at least 50 branched anal fin rays; 13-15 gill rakers on lower part of anterior branchial arch (Ref. 43912).
Inhabits flowing rivers (Ref. 4967). Feeds at least partly on aquatic and terrestrial insects (Ref. 43912). Oviparous, eggs are unguarded (Ref. 205). Maximum reported total length about 11 cm (Ref. 43912).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00562 (0.00251 - 0.01261), b=3.02 (2.82 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.2 ±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).
Vulnerability (Ref. 59153
): Low vulnerability (17 of 100) .
