Systematics: Rhizoecus keysensis is near to Rh. cacticans and measurements reveal that the labium is 65–85 μm long, length of antennae 120–150 μm long, tibia + tarsus of hind legs 95–118 μm long, the apical antennal segment is about 1.5–1.7 times as long as wide, width of anal ring (56) 60–65 μm, anal lobe setae are thin, hair-like and their maximum length is 33–55 μm, anal ring with a double ring of cells, the outer one with (20) 25–28 cells and generally three cells between anterior pair of setae. Rhizoecus cacticans on the other hand has a labium of 82–100 μm long, the length of antennae is 170–210 μm, tibia + tarsus of hind legs are 140–195 μm long, the apical antennal segment 2–2.5 times as long as wide, width of anal ring 62–75 μm, anal lobe setae are flagellate and their maximum length 75–95 μm, anal ring with a double ring of cells, the outer one with 25–32 cells and generally 4–6 cells between anterior pair of setae.
