Etymology: matthesi: Named for the collector of the type series, H. Matthes (Ref. 114247). More on authors: Poll & Gosse.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic. Tropical
Africa: Nsele River, a Malebo Pool tributary (Ref. 114247), up to Yangambi, Middle Congo River (Ref. 42033, 114247), including Ruki drainage (42033, 93897, 114247) and Kwilu (Ref. 114247), in Democratic Republic of the Congo, and Léfini River in Congo Republic (Ref. 122753).

soft rays: 8;
Vertebrae: 35 - 36. Diagnosis: Clypeobarbus matthesi is unique among congeners in pigmentation patterning on dorsal fin in which proximal third to half is smoky black and distal half is creamy white in preservation, red in life, and eye form oval vs. rounded in congeners (Ref. 114247). It differs from all except C. bellcrossi, C. congicus and C. breviclipeus in possessing large pore-bearing scales in midlateral series below dorsal fin vs. greatly enlarged, high and narrow, shield-like scales in C. pleuropholis, C. bomokandi, C. hypsolepis, C. schoutedeni and C. pseudognathodon; it is readily distinguished from C. bellcrossi in lacking a series of discrete pigment dots midlaterally along body, and from C. congicus and C. breviclipeus in lateral-line scale counts, 26-28 vs. 20-22 and 23-24 respectively (Ref. 114247).
Maximum TL was recorded at 7.9 cm (Ref. 2801).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00955 (0.00362 - 0.02520), b=3.02 (2.79 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.9 ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (14 of 100) .
