Validation characters: Translucent pores on hind coxa, trochanter, femur, and tibia; circulus small, about as long as wide; most cerarii with 2 conical setae; ventral multilocular pores on posterior 3 abdominal segments; ventral oral collars confined to posterior 4 abdominal segments.

Comparison: Dysmicoccus orchidum is similar to D. mackenziei but differs by having the cerarii anterior of the anal lobe with 2 conical setae; no discoidal pores near the eye; and 1 size of oral-collar tubular duct. Dysmicoccus mackenziei has cerarii with more than 2 conical setae; 1 or more discoidals near the eye; and 2 sizes of oral collars. This species is also similar to D. grassii but differs by having translucent pores on the hind coxa, trochanter, femur and tibia; in D. grassii these pores are restricted to the hind femur and tibia.
