Remarks

• Systematics: De Lotto (1958) synonymised it with Pseudococcus quaestitus Brain, 1915, but later, De Lotto (1977) resurrected this species. This species is most similar to Delottococcus elisabethae by lacking translucent pores on the hind femur, with less than 70 translucent pores on the hind tibia, with 17 or 18 pairs of cerarii, and without oral-collar tubular ducts near cerarius 13. Delottococcus trichiliae differs by having: (characters in brackets are those of D. elisabethae) cerarian setae on head and thorax more conical than dorsal setae (some cerarian setae thin similar to those on dorsum of thorax), antennae longer than 500 µm (less than 500 µm), femur with 20-26 setae (13-20 setae), 15-38 ventral oral-rim tubular ducts on each side of body from anterior spiracle to segment II (6-10 ducts). (Miller & Giliomee, 2011)
• Structure: Brain (1915) wrote ‘Adult female spinning ovisac, approximately 4 mm. long, pale olivaceous in colour, uniformly covered with white meal. Lateral filaments absent. Caudal filaments 2; strong, white, about one-third the length of the body. In removing insects from ovisacs these are usually broken off, so that the majority appear to have no caudal filaments. Half-grown females usually have 4 to 6 caudal filaments, the two median ones longest and thickest. Ovisac: The ovisac, when completed, is an elongate sac, which may attain 6 mm. long. It appears longer owing to the projection of the anterior half of the insect in front. The posterior half of the female is hidden by the ovisac which has parallel sides, is but slightly broader than the insect, and is broadly rounded behind. It is white and cottony, reminding one of the ovisac of a Pulvinaria.’ (Miller & Giliomee, 2011)
• General Remarks: Good description and illustration of the adult female given by Brain (1915) and by Ezzat & McConnell (1956). Good description given by De Lotto (1977). Redescription in Miller & Giliomee, 2011.
