Female: Body length 5.7–9.4 mm. Coloration, surface and vestiture as in male ( Fig. 6 ). Structure similar to male, eyes slightly larger, c. 0.2–0.33× as wide as head. Genitalia ( Fig. 19H, I, L, M ). DLP with one or two sclerotized bands; membrane encircled by the inner sclerotized band striated, sometimes with small sclerites; lateral oviducts placed close to each other, near posterior margin, almost medially; spermathecal gland placed in around midpoint of DLP or slightly above it; posterior wall with small tubercles, sometimes they absent apically, without any sclerotization; base of second valvula straight or concave; ventral wall membranous.

Distribution: Known from South-East Asia, mostly from China, Taiwan, Vietnam. Mansoniella minuta was described from Papua New Guinea ( Fig. 22 ).

Host plants: The genus has been recoded from Liquidambar formosana Hance (Altingiaceae) , Cinnamomum camphora (L.) J.Presl. ( Lauraceae ) and Sassafras tzumu Hemsl. (Lauraceae) ( Zheng & Liu, 1992; Lin, 2001, 2002).
