Grazia, J., Schwertner, C. F. & Ferrari, A., 2006, Description of five new species of Chinavia Orian (Hemiptera, Pentatomidae, Pentatominae) from western and northwestern South America, Denisia (Oxford, England) 50, pp. 423-434 : 432-433

Chinavia neoteretis nov.sp.

( Figs 5, 10, 15, 20, 34)

Description. Dorsal surface olive green with concolorous punctures ( Fig. 5). Yellow along margins of head, pronotum, basal third of corium, and connexivum. In black: spots on mesial angles of pronotum cicatricês and spots on posterolateral angles of urosternites and connexivum. Hemelytral membrane hyaline. Ventral abdominal surface uniformily green with concolorous punctures. Spiracles black. Antennae green, apex of second, apical fourth of third, almost apical half of fourth and 3/4 of fifth ferrugineous. Black line between eyes and antenniferous tubercles present. Legs uniformily green.

Médium size. Male length 13.70, width 6.78. Female length 16.89, width 8.65.

Head. Surface of juga flat, convex at apex. Proportions of antennal segments: I<II<III<IV«V. Apex of rostrum lying between hind coxae; proportions of rostral segments: I<II>III<IV.

Thorax. Anterolateral margins of pronotum straight, humeral angles rounded. Gostai angles of corium rounded, attaining posterior margin of connexival segment VI; suturai membrane margins straight. Ostiolar ruga attaining 3/4 of metapleura width. Abdominal venter convex. Medial spine of third abdominal segment short, laterally compressed, reaching hind coxae.

Male genitália. Pygophore subquadranguiar; posterolateral angles projected posteriorly (Figs 10, 15, 20). Genital cup moderately excavated. Median projection of dorsal rim subtriangular, apex truncate; lateral thirds of dorsal rim not projected over genital cup (Figs 10, 15). Flaps of the infolding of ventral rim weakly bent over genital cup, ectal surface of flaps concave; lateral margin straight, apical angles developed into a hook-like projection; mesial margin sinuous, moderately concave in posterior view. Median excavation of ventral rim narrowly "U"-shaped in ventral view (Fig. 20). Depression of ventral wall of pygophore well developed, median carina conspicuous. Dorsal surface of segment X strongly convex (Figs 10, 15), forming a basal tubular process, bifid at apex.

Female genitália. Sinuosites of posterior margin of segment VII over basal angles of laterotergites 8 inconspicuous ( Fig. 34). Surface of gonocoxites 8 nearly flat; suturai margins juxtaposed, suturai angles slightly projected mesially, posterior margins sinuate; posterolateral angles of gonocoxites 8 not developed. Spine of posterior margin of gonapophyses 9 clearly visible in posterior view. Apex of laterotergites 9 rounded, surface slightly concave, mesial margins rectilinear.

Type material. Holotype: Venezuela, Trujilo, 12.4 km NE of Bocono, along Pampan-Bocono Rd , 31.111.1992, Miller coll. (Io*, AMNH) . Paratype: same as the holotype (l ç, AMNH) .

Etymology. The name of this species reflects the similarity to C. teretis.

Distribution. Venezuela.

Comments. As mentioned previously, the abdominal spine in C. neoteretis nov.sp. is a little longer than in C. heissi nov.sp.; in females, the posterolateral angles of gonocoxites 8 are not developed, in C. heissi they are clearly developed.
