Systematics: This species is most similar to F. claviseta, F. gilli and F. quaintancii as the adult female of all four species lacks the anterior pair of ostioles, and all four species are native to the southeastern U.S.A. However F. setosa is most distinctive in having an anal ring with numerous anal ring setae (12-36, compared with six in all other Ferrisia species). Also each anal lobe cerarius has two to four conical setae, and the openings of the posterior pair of ostioles are lightly sclerotised. There are abundant setae on the abdomen and these are especially noticeable on the venter posterior to the vulva. Multilocular pores are restricted to a few around the vulva and these typically number 1-3 or can be absent. There are about 50 enlarged tubular ducts on the dorsum, mostly marginally around body and usually with one duct on each side of each abdominal segment. There appears to be no recent collections of this species. (Kaydan & Gullan, 2012)
Biology: Occurring near the roots of its host plant, under shelters built for them by ants.
General Remarks: Good description and illustration of the adult female given by Ferris (1950b). Varshney (1982) proposed the binomen Ferrisia lobdellae to replace F. setosa (Lobdell), because he regarded the latter homonymous with Dactylopius setosus Hempel. However, D. setosus is now
