Villiersicoris Delattre, 1950: 263 (gen. nov.; type species: Villiersicoris sessensis Delattre, 1950 by monotypy); Carvalho, 1952: 60 (cat.); Carvalho, 1955: 42 (key to gen.); Carvalho, 1957: 149 (cat.); Odhiambo, 1962: 311 (descr. disc.); Schuh, 1995: 533 (cat.); Schuh, 2002 –2013 (cat.).

Diagnosis: Villiersicoris is recognized by the following characters: presence of row of punctures on clavus and R + M (as in fig. 11C, D in Namyatova et al., in press); eyes stylate; ASII incrassate towards apex; AS III–IV clavate, ASIV only slightly shorter than ASIII; calli upraised; pronotum punctate, scutellum impunctate; claval commissure subequal to scutellum length; membrane cell forming right angle (as in fig. 13B Namyatova et al., in press); genital capsule without outgrowth on left-hand side ( Fig. 17 AG); and sclerotized part of phallotheca wide basally and tapering towards apex ( Fig. 17 AD).

Redescription: Male: Body length 6.9. COLORATION ( Fig. 7 ). Ground colour of body is yellow and orange, with brown and reddish markings; antennae dark brown or reddish brown. TEXTURE. Body without tubercles; flattened areas on head absent; pronotum with shallow punctures and wrinkles; scutellum without punctures, with shallow wrinkles; pair of punctures between mesoscutum and scutellum, striations on lateral margin of scutellum and row of punctures on clavus and R + M present (as in fig. 11C, D as in Namyatova et al., in press); punctures on depression delimiting calli posteriorly absent; semicircular depression between scutellum and mesoscutum absent; hemelytron rugose. VESTITURE. Body clothed with dense suberect pale setae, setae on head, pronotum and legs mostly longer than hind tibia width; femora and tibiae with black spinules, those on tibia placed in rows (as in fig. 18D in Namyatova et al., in press); tibiae not very densely setose.

Labium. Reaching posterior margin of mesosternum; LSI distinctly not reaching posterior margin of head; LSII slightly longer than LSI, LSIII slightly longer than LSII. Antenna. Reaching apex of clavus; ASI subequal to quarter of head width, twice as long as wide, widened basally; ASII 3–4× as long as ASI, with apical one third swollen, without swellings basally or medially; ASIII c. 0.6× as long as ASII, clavate, slightly longer than half of ASII; ASIV clavate, slightly shorter than ASIII. Thorax. Collar more or less delimited posteriorly, flat; calli separated, distinctly upraised, rounded; depression delimiting callosite region distinct laterally and medially; humeral angles of pronotum not dilated; posterior margin of pronotum slightly concave; scutellum only slightly upraised, acute apically, without outgrowth, medial ridge or depression; metepimeron enlarged, angulate (as in Fig. 13E ); metasternum with medial projection to abdominal segment II (as in fig. 17A in Namyatova et al., in press). Hemelytron. Costal margins straight, subparallel, claval commissure as long as scutellum, straight; R + M distinct, reaching posterior margin of corium; medial fracture strongly inclined towards midline; corium without swelling posteriorly; cuneus c. 1.25× as long as wide, c. 0.7× as long as pronotum, with medial margin straight (as in fig. 13A in Namyatova et al., in press); cuneus shorter than pronotum, base of cuneus slightly longer than half of its length; its medial margin almost straight; membrane cell slightly surpassing apex of cuneus, forming right angle (as in fig. 13B in Namyatova et al., in press), c. 0.8–0.9× as long as pronotum, auxiliary vein absent; distance from cell apex to apex of membrane c. 0.7–0.8× as long as cell length. Legs. Forecoxae contiguous (as in fig. 17A in Namyatova et al., in press); forefemora indistinctly swollen, middle and hind femora distinctly swollen; femora straight, not curved; foretibia shorter than head and pronotum combined; segment I of hind tarsus longer than segments II and III; claw with basal tooth elongate. Genitalia ( Fig. 17 AD–AG). Genital capsule as long as wide, without outgrowth(s); left paramere 3× as long as right paramere, distinctly r-shaped; phallobase sclerite of primary gonopore subtriangular, straight apically, without outgrowth(s); ductus seminis not sclerotized basally or apically, longer than phallotheca, with coils forming wide tube, attached to phallobase medially; sclerotized part of phallotheca triangular, occupying half of dorsal side, acute apically, without ridge or outgrowth; endosoma with a number of medium-sized spicules, some of them serrate.

Female: Body length 7.6. COLORATION ( Fig. 7 ). Similar to male, but paler. TEXTURE, VESTITURE AND STRUC- TURE. As in male. Generally larger than male. Genitalia. Spermathecal gland placed close to the midpoint of DLP.

Distribution: Liberia and Uganda ( Fig. 23 ).

Host plants: Unknown.
