Etymology: Nannocharax: Latin, nannus = small + Greek, charax = a marine fish without identification (Ref. 45335);  dageti: The species name, dageti, is in honor of the late Dr. Jacques Daget (1919-2009), formerly of the Muséum National d'Histoire Naturelle, Paris, in recognition of his major contributions to our knowledge of African freshwater fishes (Ref. 95523)

Africa: Kasai, Lualaba and Luapula rivers in the middle and upper Congo River basin (Ref. 95523), and the Kafue River (middle Zambezi River basin) (Ref. 95523). Based on literature (Ref. 12524, 13337, 94654), also known from the upper Zambezi River (Ref. 95523).

Short description आकृति विज्ञान | मौरफोमैटरिक्स

पृष्ठीय रीढ़ (सम्पूर्ण): 0; पृष्ठीय सौफट रेज़ (सम्पूर्ण): 12-16; गुदा कांटा 0; ऐनल सौफट रेज़: 9 - 12; जानवरों की रीड़ का जोड़: 38 - 40. Diagnosis: Nannocharax dageti is distinguished from all its congeners except N. angolensis, N. gracilis, N. lineostriatus, N. luapulae, N. macropterus and N. taenia by the colouration pattern of a series of vertically elongated, rounded blotches that overlie a longitudinal midlateral dark stripe but are largely separate dorsally from the saddles extending to the dorsal midline (Ref. 95523). Nannocharax dageti differs from N. gracilis, N. luapulae, N. macropterus and N. taenia by possessing an incompletely pored lateral line vs. completely pored lateral line, and a caudal fin with a symmetrical colouration pattern on the lobes consisting of a dark spot at the base of each caudal-fin lobe not continuous with the dark spot over the base of the middle caudal-fin rays, and a series of dark spots forming a transverse stripe paralleling the distal margin of the fin about one-third the length of the lobe from its tip (Ref. 95523). Nannocharax dageti is distinguished from N. angolensis and N. lineostriatus by possessing 40-43 scales along the longitudinal line including the lateral line, vs. 34-39 in N. angolensis and 34-35 in N. lineostriatus; 36-41 pored scales along the lateral line, vs. 21-33 in N. angolensis and 6-9 in N. lineostriatus; and 38-40 vertebrae, vs. 36 in N. angolensis and 35-36 in N. lineostriatus.

Estimates based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [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. 93245).
Trophic level (Ref. 69278):  3.1   ±0.4 se; based on size and trophs of closest relatives
लौटाव (Ref. 120179):  ऊंचा, न्यूनतम जनसंख्या दुगनी समय अवलागत 15 महीने। (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (10 of 100) .
