Diagnosis

F1 1.3× as long as wide, F1 as long as pedicel, F1 distinctly shorter than F9; head width 1.07–1.23 × (1.07) head height; head width 1.96–2.09× (1.96) interorbital space; head height 1.48–1.57× (1.57) maximum eye diameter; mesosoma slightly compressed laterally; mesoscutellum length 1.30–1.55 × (1.30) mesoscutellum width; distinct pair of translucent patches on metasomal synsternum. Male genitalia: harpe cone-shaped in ventral and dorsal view; harpe/gvc index 0.60; dorsomedial margins of harpes not touching at distodorsal margin of gvc, dorsomedial margin of harpe straight and slightly diverging distolaterally from base to apex, apex of harpe pointed; harpe with at least two lateral setae restricted to apical quarter, longest lateral setae one third as long as harpe; harpe with at least three median setae restricted to apical quarter.

Etymology

The species name is derived from the Swahili word ‘ dhahabu ’ which means ‘gold’, and the anatomical term ‘dorsal’, with reference to the dorsally golden-yellowish mesosoma.

Remarks

Comparison with similar species

Cyoceraphron dhahabudorsalis sp. nov. differs from the generally similarly coloured C. fuscopleuralis Dessart, 1978 by the reduced posterior mesosomal comb (distinct in C. fuscopleuralis ), distinctly shorter antennal segments, and the laterally less compressed mesosoma.

For more comparisons with similar species, see remarks under C. harpe sp. nov.

Condition of type material

In the holotype, the left F9, the left middle leg, and the right fore leg are missing (except coxae).
