SMITH differs from C. walikaleensis by having a clypeal process broadly semi-lunarlike excavated with long brush-like fimbriae at the corners of excision, the sterna IV and V are covered with dense erect setae and the body has more yellow colour. The female of C. iniqua KOHL shares with C. walikaleensis the dark fuscous wings but differs by having a nasiform triangularly erected clypeal process, the scutum is longitudinally rugose, which is convergent posteriorly, punctate between the rugae and the gaster (except petiole) is yellowish-brown.
