Greathead, D.J., & Pope, R.D. 1977 Studies on the biology and taxonomy of some Chilocorus spp. (Coleoptera: Coccinellidae) preying on Aulacaspis spp. (Hemiptera: Diaspididae) in East Africa, with the description of a new species.. Bulletin of Entomological Research 67: 259-270.
Notes: Field studies of predators on Aulacaspis tegalensis (Zhnt.) and laboratory breeding experiments, supplemented by taxonomic studies, showed that Chilororus discoideus Crotch and C. bilineata Korsch. are junior synonyms of C. schioedtei Muls. and that two other forms originally described as 'aberrations', may also belong to this species.
