Diagnosis: Mansoniella can be separated from other genera with rows of punctures on clavus and R + M by: ASI swollen apically (fig. 8C in Namyatova et al., in press), its length subequal to head diameter. It also can be recognized by hemelytron semitransparent with reddish, pale brown or dark brown marking on corium posteriorly; distance between eye and pronotum slightly longer than eye diameter; frons distinctly swollen ( Fig. 10A View Figure 10 ); distance between antennal fossa subequal to antennal fossa diameter; gula c. 1.5–2× as long as buccula; LSIV c. 1.5–2× as long as LSIII; calli fused ( Fig. 10A View Figure 10 ); pronotum almost without setae; depression delimiting calli posteriorly distinct medially, bearing pair of punctures ( Fig. 10A View Figure 10 ); metasternum extending to abdominal segment II in triangular outgrowth (fig. 17A in Namyatova et al., in press); posterior part of corium broadened; membrane cell forming right angle (as in fig. 13B in Namyatova et al., in press); auxiliary vein on membrane absent; coils on ductus seminis distinct, forming narrow tube; outgrowths on phallobase supporting ductus seminis very short or absent ( Fig. 16A, E View Figure 16 ), and posterior wall of bursa copulatrix with small tubercles ( Fig. 19I, M View Figure 19 ).

Redescription: Male: Body length 5.4–8.8 mm. COLORA- TION ( Fig. 6 View Figure 6 ). Head. Ground colour mostly yellow to pale brown, with reddish or brown marking on hemelytron, dorsum, sides and appendages often with reddish or brown markings. TEXTURE. Body smooth; head without tubercles or flattened areas; pronotum and scutellum mostly impunctate, without tubercles or wrinkles, only pair of punctures on depression delimiting calli and between mesoscutum and scutellum present ( Fig. 10A View Figure 10 ); striations on lateral margin of scutellum, rows of punctures on clavus and on R + M present (as in fig. 11C, D in Namyatova et al., in press); hemelytron without swelling posteriorly; semicircular depression between scutellum and mesoscutum absent. VESTITURE. Body clothed with pale short simple setae, those setae very rare or absent on head, pronotum and scutellum, dense and adpressed on hemelytron, setae on appendages dense and suberect, sometimes slightly longer than hind tibia length; setae on abdomen suberect, of varying length; black spinules on femora absent; spinules on tibia in rows (as in fig. 18D in Namyatova et al., in press). STRUCTURE. Head. Distance between eye and pronotum slightly longer than or subequal to eye diameter ( Fig. 10A View Figure 10 ); occipital region delimited with transverse depression; longitudinal depression on vertex indistinct; eyes not stylate, in line with contour of head, c. 0.25–0.33× as wide as head; distance between antennal fossa almost subequal to or slightly longer than antennal fossa diameter; frons distinctly swollen ( Fig. 10A View Figure 10 ), without swellings or outgrowths, without longitudinal depression; anterior view of head c. 1.2–1.3× as wide as high; eye almost twice as long as distance between eye and apex of clypeus; antennal fossa round, diameter subequal to third part of eye height (as in fig. 3A in Namyatova et al., in press), only slightly raised, its inferior margin placed slightly above inferior margin of eye; base of clypeus placed near inferior margin of antennal fossa, delimited with depression; in lateral view head distinctly bulged dorsally; gula c. 1.5–2× as long as buccula, straight. Labium. Reaching middle of prosternum, sometimes slightly surpassing anterior margin of metasternum; LSI–II twice as long as wide, subequal in length; LSIII c. 1.5–2× as long as wide, subequal to or slightly shorter than LSII; LSIV c. 3–5× as long as wide, c. 1.5–2× as long as LSIII. Antenna. Reaching apex of cuneus; ASI subequal to or slightly shorter head width, swollen apically (fig. 8C in Namyatova et al., in press); ASII c. 2–3× as long as ASI, subequal to or slightly longer than head and pronotum combined; ASIII slightly shorter than ASII; ASIV c. 0.3– 0.4× as long as ASIII; ASII–IV filiform. Thorax. Collar distinct, fused with calli posteriorly, upraised; calli fused with each other, distinctly separated posteriorly by depression ( Fig. 10A View Figure 10 ); humeral angles of pronotum rounded, not dilated ( Fig. 10A View Figure 10 ); posterior margin of pronotum straight or slightly concave or sinuate; scutellum almost flat, acute apically, without outgrowth, ridge or medial depression; metepimeron enlarged, c. 3–4× as high as long, rounded or angulate and subtriangular; metasternum extending to the abdominal segment II in triangular outgrowth (as in fig. 17A in Namyatova et al., in press). Hemelytron. Costal margins of hemelytra convex near posterior margin of corium, hemelytra widened posteriorly; claval commissure twice as long as scutellum, straight; R + M distinct, reaching posterior margin of corium; medial fracture inclined towards midline; corium without swelling posteriorly; cuneus c. 2–2.5× as long as wide, as long as or slightly shorter than pronotum, medial margin almost straight; membrane cell slightly surpassing apex of scutellum, forming right angle (as in fig. 13B in Namyatova et al., in press), slightly longer than pronotum; auxiliary vein absent; distance from cell to apex of membrane c. 1.5× as short as length of membrane cell. Legs. Forecoxae contiguous (as in fig. 17A in Namyatova et al., in press); fore- and middle femora slightly swollen apically, hind femur distinctly swollen apically; femora straight or only indistinctly curved; tibiae without swellings; foretibia shorter than head and pronotum combined; segment I of hind tarsus slightly longer than segment II, and subequal to or slightly shorter than segment III (as in fig. 19A in Namyatova et al., in press); most part of claw straight, apical third part curved; basal tooth on claw more than twice as long as wide, concave (as in Fig. 13K View Figure 13 ). Genitalia ( Fig. 16A–H View Figure 16 ). Genital capsule as wide as or wider than long, without any outgrowths; left paramere three times as long as right paramere, distinctly r-shaped; sclerite around primary gonopore heart-shaped or bowl-shaped, sometimes with short outgrowths, supporting ductus seminis; ductus seminis not sclerotized basally or apically, distinctly shorter than phallotheca length, with coils forming narrow tube, attached to phallobase medially; sclerotized part of phallotheca broad, occupying entire dorsal part, rounded apically, without outgrowth or ridge; endosoma with or without spicules at base, areas of small spicules absent.

Female: Body length 5.7–9.4 mm. Coloration, surface and vestiture as in male ( Fig. 6 View Figure 6 ). Structure similar to male, eyes slightly larger, c. 0.2–0.33× as wide as head. Genitalia ( Fig. 19H, I, L, M View Figure 19 ). 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 View Figure 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).
