DISTRIBUTION: Afrotropical: South Africa [DeLott1977, BenDov1994]. Australasian: Hawaiian Islands [MillerGi2011]. Nearctic: United States of America (California [MillerGi2011] (D. confusus, a species previously known only in South Africa, was discovered in 2003 at a nursery in southern California on Protea and has since been recorded on Leucadendron and Protea at several nurseries in central and southern California; on one occasion, Leucadendron plants were being defoliated by the infestation. The species is not regarded as established in California, and any infestations found are eradicated.)).
GENERAL REMARKS: Good description and illustration of the adult female given by De Lotto (1977). Redescription and illustrations in Miller & Giliomee, 2011)
STRUCTURE: Body of adult female grey or greyish green, with three or four pairs of lateral filaments, posterior-most pair is longest, about one third the length of the body. Feeding and ovipositing females occur on the undersides of leaves. The ovisac is white covering all but the anterior portion of the head, about three times the length of adult female body. The eggs are bright yellow when first laid but turn orange as they develop. (Miller & Giliomee, 2011)
SYSTEMATICS: De Lotto (1977) referred to this species the syntypes of Pseudococcus trichiliae Brain taken on Leucadendron argentatum in Rosebank (Cape Town), South Africa. This species is most similar to Delottococcus trichiliae, lacking translucent pores on hind femur, having 19 or more setae on each hind femur, and lacking oral-collar tubular ducts near cerarii 12 and 13. Delottococcus confusus differs by having: (characters in brackets are those of D. trichiliae) more than 70 translucent pores on hind tibia (fewer than 70); some cerarian setae on head and thorax similar in thickness to dorsal setae (cerarian setae on head and thorax thick and more conical than those on dorsum of thorax). (Miller & Giliomee, 2011)
