Systematics: This species is most similar to O. pentziae; Octococcus pentziae differs by having (character states in brackets are those of O. warniae): few large-sized oral-rim tubular ducts, segment IV with two to five such ducts (many large-sized oral-rim tubular ducts, segment IV with 12–19 such ducts); large-sized oral-rim tubular ducts in incomplete transverse rows across abdominal segments (complete rows); with three to five suranal setae (seven to 12 setae). (Miller & Giliomee, 2016)
Structure: Adult female dark grey or black, enclosed in a white sac. First instars are the same colour as the adult female; with one pair of filaments equal in length to about quarter the length of the body; posterior medial wax projection from anal ring about the same length as the filaments; posterior four segments with white wax, the rest of the body is bare.
Economic Importance: This is the only species that has been intercepted at United States ports-of-entry. Because the Metalasia host is a member of the Asteraceae and because this plant family contains many environmentally and economically important plants, it is important to be vigilant about keeping this mealybug from becoming established outside of its normal geographic range.
