Sculpture of marginal depression of S 5 in female: rugulose. Apical spine on S 6 in female: extending beyond apex of T6 and visible in dorsal view. Diagnosis . Oreiscelio majikununuensis is most similar to Oreiscelio cultrarius in general appearance. Th e females may be separated from all other species of Oreiscelio by the straight posterior margin of the propodeum ( Fig. 76 ). Th e long ventral mandibular tooth ( Figs 77, 78 ) represents the largest size difference between mandibular teeth in Oreiscelio . Etymology . The type specimen was collected in an isolated patch of Afromontane forest on a mountain called Maji Kununua, which is Swahili for “place of water”. Link to distribution map. 37 Material examined.
