Olesicampe alboplica (Thomson, 1887)

This genus has yet to be revised and was thus treated with care. Keying was done with SCHMIEDEKNECHT (1908). Olesicampe spp. are not very difficult to recognise. Their fore wing has a closed areolet, the nervellus is not broken, their clypeus is long, the upper tooth of the mandibles is (often) shorter than the lower tooth and the ovipositor is fairly short but straight (more details see SCHMIEDEKNECHT, 1908 and TOWNES, 1970b).

For this species, the dorsolateral carinae and glymmae are present on the petiole. The metasoma is completely black. The hind tibiae are black apically, the femora are completely black. Some of the known hosts are said to be the very rare sawflies Aglaostigma nebulosum (Ed. Andre, 1881) and Siobla sturmi (Klug, 1817) (Symphyta: Tenthredinidae ) (HINZ, 1961).
