Diagnosis
Anteromedian projection of the metanoto-propodeo-metapecto-mesopectal complex curved in lateral view with pointed end. Male genitalia: harpe cone-shaped in ventral and dorsal view; harpe/gvc index 0.37; 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 one lateral seta restricted to apical quarter; longest apical setae more than two thirds as long as harpe; genitalia moderately sclerotized with strongest sclerotization at aedeagus + gonossiculus and weakest sclerotization at harpe.
Etymology
The species is named after the town Kaimosi in the Kakamega Forest region which is the type locality.

Remarks
Comparison with similar species
The male genitalia of C. kaimosiensis sp. nov. and C. sp. 5 are very similar. However, in C. kaimosiensis the harpe is the most weakly sclerotized structure of the genitalia, and in C. sp. 5 all margins of the harpe are the most strongly sclerotized structures of the genitalia. Furthermore, the harpe/gvc index of C. kaimosiensis is 0.37 and that of C. sp. 5 is 0.42, the gvc width is more than two thirds of the gvc length in C. kaimosiensis and less than two thirds in C. sp. 5, and the setal arrangement and relative length of the setae differ between the two species.
Condition of type material
In the holotype, the end of the metasoma is slightly deformed, thus the body length measurement is not precise.
