Female: Body length 9–10 mm. Coloration similar to male, abdomen reddish ( Fig. 7 ). Surface and vestiture as in male, setae on abdomen dark and suberect of different length, sometimes twice as long as hind tibia width. Structure similar to male, but body generally larger, pronotum wider than in male, and hemelytron slightly widened posteriorly. Genitalia ( Fig. 21I, J ). DLP with two distinct sclerotized bands, without striations or sclerites, lateral oviducts and spermathecal gland placed posteriorly, not shifted right or left, lateral oviducts distinctly removed from each other, but placed far from lateral margins of DLP; posterior wall of bursa copulatrix with small tubercles, without sclerites; base of second valvula distinctly swollen; ventral wall membranous.

Distribution: Known from Ghana and Democratic Republic of Congo ( Fig. 24 ).

Host plants: Poppiusia leroyi was recorded from Combretum sp. and Combretorum racemosum (Combretaceae) ( China, 1944; Leston, 1980).
