Scape, pedicel and flagellum brown; sensillae on flagellomeres distinctly shorter than width of flagellomeres; posterolateral processes of gena present; head width 2.06–2.14 × (2.10) interorbital space; OOL:LOL 2.78–3.03 (2.78). Male genitalia: harpe cone-shaped in ventral and dorsal view; harpe/gvc index 0.43; dorsomedial margins of harpes slightly converging and not touching at distodorsal margin of gvc, dorsomedial margin of harpe straight and slightly diverging distolaterally from base to apex; harpe with at least ten brush-like arranged and slightly convex median setae; harpe with at least two lateral setae restricted to apical half; dorsal area of gvc indented distomedially; genitalia moderately sclerotized with strongest sclerotization at distal half of gvc and apical aedeagus + gonossiculus and weakest sclerotization at harpe.
Etymology
The species is named after the Nandi people, an ethnic group in the south-eastern Kakamega Forest area.

Female
Unknown.
Variation
Translucent patches are absent in ZFMK-HYM-00036868 and the proximodorsal margin of the gvc is slightly concave in ZFMK-HYM-00036868. The posterolateral processes of the gena are differently shaped in the paratypes.
Biology
Host unknown, specimens collected from leaf litter.
Distribution
Afrotropical: Kenya.
Remarks
Comparison with similar species
See remarks under C. chemositi sp. nov. and C. mamamutere sp. nov.
Condition of type material
In the holotype, left F7–F9 and right F8 and F9 and the right hind wing are missing. The posterior part of the metasoma is missing, thus the body length measurement is not precise.
