Male genitalia in ventral (A), lateral (B) and dorsal (C) views. D . Habitus in lateral view. Female Unknown. Variation The flagellum gradually darkens from F1 to F 9 in ZFMK-HYM-00036777 and ZFMK-HYM-00036780. Biology Host unknown, specimens collected from leaf litter. Distribution Afrotropical: Kenya . Remarks Comparison with similar species See remarks under C. tiriki sp. nov. , C. semira sp. nov. , and C. eaerendili sp. nov. Condition of type material In the holotype , the end of the metasoma is slightly deformed, thus the body length measurement is not precise.
