Remarks

• Systematics: The adult male of Ri. kondonis differs significantly from other apterous rhizoecine males in having: (i) no eyes; (ii) only a single tarsal segment; and (iii) trochanter with only 2 pairs of campaniform pores. In addition, Ri. kondonis has: (i) an aedeagus with a bifid apex; (ii) metatarsi with a particularly large ventral spur, and (iii) head with an additional pair of ridges extending posteriorly from preocular ridge. Ri. kondonis is, none-the-less, otherwise a typical rhizoecine male.
• Structure: McKenzie (1960, 1967) provided colour photograph of this mealybug and the damage that it causes. Colour photograph given by Kawai (1980). Female Antennae 5o-segmented. Cephalic plate not visible. Ostioles well developed. Circulus large, convex. (Danzig & Gavrilov-Zimin, 2015)
• Biology: Occurring on the roots of its host plants (Yoshida & Kubota, 1962; McKenzie, 1967). Yoshida & Kubota (1962) reported up to three annual generations in Japan.
• Economic Importance: McKenzie (1960, 1967) considered this species to be one of the more widespread and economically important subterranean mealybugs in California, where it is a pest of alfalfa, prune trees and strawberry plants. Severe damage to citrus in Japan was reported by Yoshida & Kubota (1962).
• General Remarks: Description and illustration of adult female by Ferris (1953a) (as R. spinosus, McKenzie (1967) (as R. spinosus, Kawai & Takagi (1971a), Hambleton (1976), Williams & Granara de Willink (1992) and by Kozár & Konczné Benedicty (2007).
