( figs. 3 B View FIGURE 3 ; 8 H)

Etimology. The epithet refers to the color of the abdomen, coppery brown; latin: cupreus , copper colored.

Type locality. Brazil, Piracicaba (- 22.7167; - 47.6333).

Female holotype. BRAZIL, São Paulo: Piracicaba, 11.XI. 1965, C. A. Triplehorn, [- 22.7167; - 47.6333], black light, (DBTC) Deposited in: USNM. GoogleMaps

Description. Oval elongated body, coppery brown; punctures brown forming wrinkles on pronotum; small light brown spots on scutellum and hemelytra. Legs light brown, contrasting with body. Antennae four-segmented. Head with punctures forming wrinkles on mandibular plates. Apices of mandibular plates not touching each other, exceeding clypeus by a distance equivalent to the ocellar diameter; lateral margins of mandibular plates reflected, ventrally yellowish. Anteocular processes projected, attaining half the width of eye. Eyes on short peduncle. Antennal tubercle covered dorsally by anteocular process. Antennae brown, four-segmented; first segment bearing dorsal longitudinal light spot; proportion of antennal segments: I<II≈III<IV, fourth the longest. Ventrally with 1 + 1 yellowish carinae posterior to the eyes. Bucculae without anterior tooth. Rostrum yellowish, second segment reaching mesocoxae; apex on urosternite V; proportion of rostral segments: I<II>III>IV.

Pronotum with punctures forming wrinkles posterior to cicatrices; few yellowish spots, denser on anterior half of disc; cicatrices slightly tumid. Anterior angle of pronotum with projections parallel to posterior margins of eye, exceeding laterally the eye by half the eye diameter. Anterolateral and posterolateral margins subrectilinear. Scutellum with yellowish spots denser on post-frenal lobe; anterior margin with 1 + 1 yellowish spots near the fovea; punctures forming wrinkles denser on lateral margins. Corium reaching posterior margin of connexival segment VI; spot on apex of radial vein twice the ocellus diameter. Hemelytral membrane not surpassing the apex of abdomen, bearing six veins. Pleurae with light brown spots; sterna brown. Evaporatorium brown; peritreme reaching half the width of evaporatorium. Legs light brown, contrasting with body color; femora with few brown circular spots.

Segments of connexivum bearing middle yellowish spot. Abdomen uniformly coppery brown; punctures inconspicuous on lateral margins and absent on median disc. Yellowish maculae before spiracles present (fig. 8 H).

Female. Measurements (n= 1): head length, 1.09; width, 1.71; pronotum length, 1.64; width, 3.88; scutellum length, 3.04; width, 2.48; length of antennal segments: I, 0.48; II, 1.14; III, 1.16; IV, 1.48; length of rostrum segments: I, 0.85; II, 1.60; III, 1.15; IV, 1.00; total length, 8,06; abdominal width, 4.19.

Genitalia. Gonocoxites 8 longer than wide; posterior margins sinuous; middle projection over laterotergites 9 slightly longer than posterolateral projection over laterotergites 8; sutural margins with few short setae, densely on apical third; disc with low callus on middle, near posterior margin (fig. 8 H). Laterotergites 8 wider than long, posterior half light brown (fig. 8 H). Gonocoxites 9 triangular; longitudinal suture conspicuous (fig. 8 H). Laterotergites 9 not reaching the band connecting laterotergites 8; sutural angles not touching each other; apex truncated (fig. 8 H).

Male. Unknown.

Comments. Xynocoris cupreus sp. nov. ( fig. 3 B View FIGURE 3 ) is part of the apical polytomy within the ‘clade Q’ ( fig. 1 View FIGURE 1 ; Garbelotto et al. 2013, ‘sp. 18 ’). Diagnostic characters are the elongated body, the legs with few circular brown spots, the abdomen without punctures on disc and the shape of the genital plates (fig. 8 H).
