Male genitalia
Genital capsule quadrangular; ventral rim deeply excavated concave, with median conical projection; two stout finger-like projection submedially inner to median conical projection; caudal lobes indistinct with apex angulate; dorsal rim widely and deeply excavated concave between caudal lobes. Paramere crown finger-like gradually tapering towards apex; phallus with phallotheca short, pear-like, less sclerotized.
Female genitalia

Spermatheca with spermathecal dilation; apical receptacle elongate and conical.
Biology
Female lay about 100-200 eggs singly or in small clusters of 2–13 eggs on aerial plant parts. Newly deposited eggs are dirty white with reticulated surface, later change to orange-red. Incubation period of 2–6 days, nymphal duration 17-33 days and adult longevity 8 to 26 days (Palumbo et al., 2016).
