Male genitalia: harpe cone-shaped in ventral and dorsal view; harpe/gvc index 0.67; dorsomedial margins of harpes almost touching at distodorsal margin of gvc, dorsomedial margin of harpe straight from base to apex, apex of harpe rounded, slightly oriented distolaterally. Etymology The species name is derived from the Swahili word ‘ njano ’ which means ‘yellow’, with reference to the yellowish body colouration.

Variation Unknown. Biology Host unknown, specimen collected from leaf litter. Distribution Afrotropical: Kenya . Remarks Comparison with similar species See remarks under Cyoceraphron invisibilis sp. nov. and Ceraphron cingulum sp. nov. Condition of type material In the holotype , the right F4 to F9 and the tarsal segments 3 to 5 of the right hind leg are missing. The posterior part of the metasoma is missing, thus the body length measurement is not precise.
