Remarks

• Systematics: Dysmicoccus kaiensis (Kanda 1932) is similar to D. pauper (Danzig 1971) in having some cerarii situated on sclerotized plates. However, D. kaiensis differs from P. pauper as follows (contrasting character states in D. pauper in parentheses): (i) hind legs without translucent pores (translucent pores present on hind femora and tibiae); and (ii) circulus present between abdominal segments III and IV (circulus absent). D. kaiensis is also similar to F. kawaii in having a large number of cerarii (≧17 pairs). However, D. kaiensis differs from F. kawaii by having the penultimate cerarii (C17) located on heavily sclerotized plates, whereas in F. kawaii the penultimate cerarii are located on membranous cuticle. (Tanaka, 2022)
• Structure: Slide-mounted adult female elongate oval, 2.9–4.8 mm long and 1.2–2.4 mm wide; derm membranous; segmentation recognizable but not well developed. Anal lobes moderately developed, dorsal and ventral surfaces of each lobe with strongly sclerotized large plates, and ventral surface with a long apical seta, 156–220 μm long; anal lobe bar absent. Antenna 388–598 μm long, with 6–8 segments (usually 8) and many flagellate seta. (Tanaka,, 2022)
• General Remarks: Good description and illustration of the adult female given by Danzig (1980b). Good description of the adult female given by Takahashi (1958) and by Tang (1992). Detailed redescription and illustration by Tanaka (2022).
