Mealybugs of the genus Pseudoferrisia will key to Ferrisia in any key published prior to 2012 to genera of mealybugs that includes Ferrisia. Adult females of these two genera can be distinguished mostly readily as follows [Ferrisia in brackets]: Antennae 6 segmented [Antennae 7 or 8 segmented]; circulus absent [circulus present]; anal lobe cerarii each with >5 cerarian setae, with cerarii or partial cerarii present on 2 or more segments anterior to anal lobes [cerarii confined to anal lobes, each lobe usually with 2 (rarely 3-5) cerarian setae]; setae on sclerotised area around orifice of dorsal enlarged tubular ducts slender spinelike; [setae on sclerotised area around orifice of dorsal enlarged tubular ducts slender and bluntly tipped to slightly capitate] dorsal setae spine-like; oral-rim tubular ducts present on venter [dorsal setae flagellate and bluntly-tipped to slightly capitate; oral-rim tubular ducts absent]. (Kaydan & Gullan, 2012).
- Structure: Ferris (1953) described and illustrated the adult female of an unusual species of mealybug from Florida, U.S.A., and placed it in the genus Ferrisiana Takahashi as F. floridana Ferris, along with four other species, F. claviseta, F. quaintancii (misspelled as F. quaintancei), F. setosa and F. virgata. McKenzie (1967) transferred these five species to Ferrisia. Although the adult female of F. floridana has enlarged tubular ducts on the dorsum, these ducts differ structurally from those of other Ferrisia species. F. floridana also is distinctive in possessing six-segmented antennae (eight, rarely seven, segments in other species) and more than one pair of cerarii (all other Ferrisia species possess only anal lobe cerarii), plus some, slender cerarian-type setae more anteriorly on the abdominal margin and on the head.
