  Ferrisia cristinae is most similar to specimens of F. williamsi from Colombia, but in F. cristinae the discoidal pores associated with ventral oral-collar tubular ducts often do not touch the duct rim (in F. williamsi any minute discoidal pores associated with the ducts always touch the rim of the duct opening); furthermore, the translucent pores on the hind coxa of F. cristinae are mostly 0.5-2.0 ìm in diameter (mostly 2.0-3.0 ìm in diameter in F. williamsi). F. cristinae can be distinguished readily from F. kondoi by having scattered translucent pores on the hind coxa (none on hind coxa of F. kondoi), fewer trilocular pores on the anal lobes (35-45 on each lobe of F. cristinae; 58-62 on F. kondoi), and fewer ventral oral-collar ducts on the body (56-75 on F. cristinae; 87-113 on F. kondoi; excluding those on the posterior abdominal margin) but especially on the posterior abdominal segments where the number of ventral oral-collar tubular ducts is less than half of the number present in F. kondoi. The adult female of F. cristinae differs from that of F. virgata in the position of the discoidal pores, having 1 or 2 pores adjacent to the opening of most dorsal enlarged ducts and ventral oral-collar tubular ducts (discoidal pores never adjacent to duct openings in F. virgata). F. cristinae can be separated from F. milleri and F.ecuadorensis by the absence of small clusters of oral-collar tubular ducts on the head, thorax and anterior abdominal segments. F. cristinae can be distinguished readily from F. uzinuri by having clusters of small oral-collar tubular ducts on the ventral margins of the posterior abdominal segments (absent in F. uzinuri). (Kaydan & Gullan, 2012)

• Structure: Ferrisia cristinae can be diagnosed by the following combination of features: presence of a few (1-6 per segment) small oral-collar tubular ducts usually scattered on ventral margins of last 2-3 abdominal segments; ventral oral-collar tubular ducts generally with a minute discoidal pore touching rim of duct opening (sometimes slightly away from duct opening); dorsal enlarged tubular ducts totalling 95-113 throughout dorsum, with 1 or 2 oval discoidal pores sometimes adjacent to rim of each duct opening; number of multilocular disc-pores on venter of abdominal segments as follows: segment VI (7 or 8), VII (15-22), and VIII + IX (13-19); anal lobe cerarii each with 2 conical setae; both pairs of ostioles present and pairs well developed; translucent pores scattered on dorsal surface of at least hind coxa.
