Etymology: Chiloglanis: Greek, cheilos = lip + Greek, glanis = a fish that can eat the bait without touching the hook; a cat fish (Ref. 45335); kazumbei: This species is eponymously named for Mr. George Kazumbe, an expert fisherman and friend from Kigoma, Tanzania; he has assisted the authors and several of their colleagues doing fieldwork in Tanzania, and the authors wish to honor him for his service (Ref. 87986).
Eponymy: George Kazumbe from Kigoma, Tanzania, is described as an ‘expert fisherman and friend’. [...] (Ref. 128868), visit book page.

Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 2; Raggi dorsali molli (totale) : 5 - 6; Spine anali: 0; Raggi anali molli: 10 - 11; Vertebre: 34 - 35. Diagnosis: Chiloglanis kazumbei can be distinguished from all species in the Malagarasi and Luiche basins by the following combination of features: relatively long dorsal spine length, 16.1–21.3% of standard length vs. 7.5–13.6% in C. asymetricaudalis, 8.2–12.7% in C. igamba and 4.1–7.8% in C. orthodontus; relatively long pectoral spine length, 19.1–23.6% of standard length vs. 12.1–16.5% in C. asymetricaudalis, 9.9–15.1% in C. igamba and 10.9–17.2% in C. orthodontus; relatively wide occipital shield width, 6.1–8.3% of standard length vs. 3.7–4.7% in C. asymetricaudalis, 2.8–4.9% in C. igamba and 2.4–3.8% in C. orthodontus; and moderately long adipose fin length, 17.1–22.8% of standard length vs. 13.3-19.8% in C. asymetricaudalis, 10.3–16.3% in C. igamba and 25.0-31.3% in C. orthodontus (Ref. 87986). Additional features that distinguish C. kazumbei from congeners within its range include a distinctive pigmentation pattern with dark patches on the dorsal and pectoral fins, a dark band on the anal fin, and a caudal fin that is deeply forked with a slightly longer lower lobe vs. not deeply forked in C. lufirae, C. igamba and C. orthodontus, or forked with greatly elongated upper lobe in males of C. asymetricaudalis (Ref. 87986).
This species is typically found in small to moderate sized rapids (Ref. 87986).
