  Ferrisia ecuadorensis is most similar to F. milleri, F. kondoi and F. virgata but the adult female is much more slender than the latter three species. The slide-mounted adult female of F. ecuadorensis can be distinguished readily from other species in the genus by having clusters of small oral-collar tubular ducts on the ventral margins of all abdominal segments except segment I (present only on segments VI-VII or VII-VIII in F. kondoi and on VII-VIII in F. virgata), and each duct is distinctively shaped with a slanted inner end and a long filamentous inner ductule. The adult female of F. ecuadorensis also differs from those of F. virgata in the position of the discoidal pores, which are usually always found adjacent to the rim of duct openings of both enlarged ducts and ventral oral-collar tubular ducts (discoidal pores never adjacent to rim of duct openings in F. virgata). Ferrisia ecuadorensis also is similar to F. milleri but it can be separated from this species by the absence of clusters of small oral-collar tubular on head and thorax (present in F. milleri). (Kaydan & Gullan, 2012)

• Structure: Ferrisia ecuadorensis has the following combination of features: presence of large clusters of small oral-collar tubular ducts on ventral margins of all abdominal segments except abdominal segment I; ventral oral-collar tubular ducts generally with a minute discoidal pore touching rim; dorsal enlarged tubular ducts totalling 98 throughout dorsum, with 1 or 2 oval discoidal pores usually adjacent to rim of each duct opening; number of multilocular disc-pores on venter of abdominal segments as follows: segment VI (3), VII (16), and VIII + IX (12); anal lobe cerarii each with 2 conical setae; both anterior and posterior pairs of ostioles present and well developed.
