Diagnosis
OOL:POL 3.33; anteromedian projection of the metanoto-propodeo-metapecto-mesopectal complex curved in lateral view with blunt, lighter and emarginated end, exceeding end of mesosoma. Male genitalia: harpe cone-shaped in ventral and dorsal view; harpe/gvc index 0.52; dorsomedial margins of harpes slightly converging and not touching at distodorsal margin of gvc, dorsomedial margin of harpe straight and diverging distolaterally from base to apex, apex of harpe slightly rounded; longest apical setae slightly less than as long as harpe; genitalia weakly sclerotized, almost transparent; gvc width more than three quarters of gvc length; Weber length 3.44 × genital length.
Etymology
The species is named after the Nzoia River which is close to the type locality.

Remarks
Comparison with similar species
Ceraphron nzoia sp. nov. can be distinguished from all other treated species by the combination of a high OOL:POL (3.33), weakly sclerotized, almost transparent genitalia, a high Weber length to genital length ratio (3.44), and apical seate on the harpe which are almost as long as the harpe.
Condition of type material
In the holotype, the right F9, both fore wings and the right hind wing are missing. The posterior end of the metasoma is slightly deformed, thus the body length measurement is not precise.
