Hodgson, C.J.Millar, I.M.Gullan, Penny J2015-12-101175-5326http://hdl.handle.net/1885/63127The gall-inducing genus Cissococcus Cockerell is revised to include two species. The family placement of Cissococcus has been uncertain, but characters of the first-instar nymph and adult male clearly show that Cissococcus is a soft scale insect (Coccidae) and is therefore the only member of the Coccidae known to induce a complex covering gall. All stages of the type species, C. fulleri Cockerell, are described and illustrated, plus the adult and third-instar female and first-instar nymph of a new, closely-related species, C. braini Hodgson & Millar sp. n. Both species are known only from wild vines in the southeast and C. fulleri also in the northeast of South Africa, but each induces a unique gall and each appears to be restricted to a different species of Rhoicissus (Vitaceae). The galls of each species are described and figured, and gall induction in the Coccidae is briefly discussed.Keywords: Coccidae; Coccoidea; Eriococcidae; Hemiptera; Hexapoda; Rhoicissus; Vitaceae Cissococcinae; Eriococcidae; Rhoicissus20112016-02-24
