Taxonomical remark: This new species belongs to Olesicampe s.str., e. g. species with larger ventral mandibular tooth, long temples and silvery setae of the face. It is characterized by the partly yellow clypeus (fig. 17), red hind femur and enlarged hind trochantellus (fig. 19) and differs mainly from O. flavicornis THOMSON (sometimes with red hind femur) by the enlarged hind trochantellus, darker coxae, and black hind edge of pronotum.
