Measurements.

Female (n=1). Body length 10.00; abdominal width 5.91; head length 1.38; head width 2.01; pronotum length 2.14; pronotum width 5.54; scutellar length 4.03; scutellar width 3.33; length of antennal segments: I 0.63; II 0.75; III 1.01; IV 1.26; V 1.89.

Male (n=4, except for antennal segment V where n=3). Body length 9.12–9.56 (9.34, 0.20); abdominal width 5.28–5.72 (5.54, 0.20); head length 1.13–1.38 (1.29, 0.12); head width 1.95–2.14 (2.04, 0.08); pronotum length 1.89–2.20 (2.00, 0.14); pronotum width 5.03–5.41 (5.24, 0.17); scutellar length 3.77–3.96 (3.88, 0.08); scutellar width 3.15–3.46 (3.33, 0.14); length of antennal segments: I 0.57–0.69 (0.61, 0.06); II 0.69–0.88 (0.77, 0.08); III 1.01–1.13 (1.07, 0.05); IV 1.20–1.26 (1.24, 0.03); V 1.70–1.82 (1.76, 0.06).

Description. Body elliptical, brown to dark brown (fig. 3). Dorsal surface densely punctured in concolorous or slightly darker punctures. Ventral surface sparsely punctured in concolorous or darker punctures, except abdomen unpunctured.

Head unpunctured or with few punctures on juga. Vertex and central disk of tylus swollen (fig. 3). Lateral margins of juga sinuous and emarginated; dorsal surface of tylus and juga with transversal furrows at base. Ocelli near posterolateral margin of head. Antennal segments brown, except basal third of segment V yellowish. Apical segment of rostrum attaining posterior margin of urosternite VI.

Pronotum with conspicuous, dark brown to black cicatrices bearing 1+1 small, central tubercle. Anteroapical tooth triangular, cephalad produced, yellowish at apex. Legs brown to dark brown.

Scutellum with three basal spots: one mesial, larger; 1+1 smaller, near basal angles. Hemelytra finely and densely punctured, with 1+1 small yellowish spot near apex of radial vein; membranes dark brown.

Connexiva narrowly exposed, each segment bearing a mesial yellowish macula.

Abdominal venter unpunctured and finely covered by short setae; mesial, longitudinal sulcus extending from sternite III to VI; stripe between spiracles and abdominal margin smooth, lacking setae, punctures fine to absent.

Female. Genital plates (fig. 4) plain. Gonocoxites 8 produced well caudad over laterotergites 9, posterior margin subtruncated, mesial half flat. Laterotergites 9 finger­like, tumid at apex and attaining band uniting laterotergites 8.

Male. Pygophore (figs. 5–6). Dorsal rim evenly concave; ventral rim profoundly con­

cave between posterolateral angles, these somewhat rounded and tumescent. Area between

superior and inferior layers of ventral rim (sl, il) strongly excavated. Parameres (fig. 7).

Anterior lobe trapezoidal, apical margin (am) concave. Proctiger (figs. 6, 8). Lateral pro­

cesses almost attaining lateral margin of pygophore; 2+2 hair fringes over dorsoposterior

surface of proctiger, 1+1 apical and 1+1 subapical near base of lateral processes. Phallus (fig. 9). Vesica opened dorsocaudad; dorsal process of vesica long, its length almost twice width of aperture of vesica; vesica with ventral, mesial finger­like process, its length equal to maximum height of vesica.

Distribution. Brazil: Minas Gerais and São Paulo.

Comments. C. lucida Campos & Grazia , sp. nov. resembles C. pensa by the swollen vertex and the body size. The new species can be distinguished from C. pensa by characteristics of male and female genitalia: the shape of the pygophore (primarily the ventral rim) and parameres, the presence of a ventral process at vesica and the narrower vesical aperture, the shape and extension of gonocoxites 8.
