Etymology
The species name is derived from the Swahili word ‘ kahawia ’ which means ‘brown’, with reference to the brown body colouration.

Variation
The paratype ZFMK-HYM-00037085 has a darker body colouration, and the male genitalia are slightly more sclerotized at the apex of the harpes and at the distal gvc.
Biology
Host unknown, specimens collected with coloured pan traps.
Distribution

Remarks
Comparison with similar species
Cyoceraphron kahawia sp. nov. can be distinguished from all other species of Cyoceraphron by the distinct and unique overall brown body colouration (meso- and metasoma light brown-yellowish or partially golden-yellowish in other species of Cyoceraphron ). Additionally, C. kahawia can be separated from C. harpe sp. nov. by a distinctly different harpe shape (cone-shaped in C. kahawia and sickle-shaped in C. harpe ) and from C. dhahabudorsalis sp. nov. by distinctly longer flagellomeres (e.g., F1 2.4× as long as wide, F1 1.8× as long as pedicel, F6 2.0× as long as wide in C. kahawia and F1 1.3× as long as wide, F1 as long as pedicel, F6 1.1× as long as wide in C. dhahabudorsalis ). Additionally, C. kahawia can be separated from C. njano sp. nov. by a higher genital length to gvc width ratio (2.14 in C. kahawia and 2.00 in C. njano ), and by a gvc width of two thirds of gvc length in C. kahawia and a gvc width of more than three quarters of gvc length in C. njano . The ventral, lateral and dorsomedial margins of the harpe also differ in both species. Moreover, the dorsal and dorsomedial margins of the harpe distinctly differ between C. kahawia and C. invisibilis sp. nov. and the gvc width is two thirds of the gvc length in C. kahawia and alsmots equal in C. invisibilis . The harpe/gvc index of C. kahawia is distinctly lower with 0.58 than that of C. invisibilis with 1.00.
Condition of type material In the holotype, the left F7 to F9, the left hind leg (except coxa), and the right fore and hind wings are missing. F9 of the right antenna is compressed. The metasoma is detached and deformed and the posterior part is missing, thus the body length measurement is not precise.
