Chinavia boliviensis, Grazia & Schwertner & Ferrari, 2006

Chinavia boliviensis nov.sp.

( Figs 2, 6, 11, 16)

Description. Dorsal surface dull green, densely punctured with concolorous punctures, finer and denser on head, pronotum and scutellum ( Fig. 2). Yellow band along margins of head, pronotum, basal third of corium and connexivum. In dark-castaneous to black: line on lateral margins of juga, very apex of scutellum, spots on posterolateral angles of urosternites scarcely extending onto connexivum. Hemelytral membrane hyaline. Ventral surface greenish on thoracic pleura and margins of abdómen laterad of spiracles; yellow on sterna and abdominal disc. Spiracles dull green, each placed on an inconspicuous yellow callus. Black line between eyes and base of antenniferous tubercles present. Antennae olive green; apical half of third, fourth and fifth segments ferrugineous. Legs uniformly green.

Médium size. Male length 14.9, width 6.2.

Head. Jugal surfaces flat, margins convex to apex, convergent to each other. Proportions of antennal segments: I<IWII<IV=V. Apex of rostrum lying between hind coxae. Proportions of rostral segments: I<II»III>IV.

Thorax. Anterolateral margins of pronotum inconspicuously convex, humeral angles right angular. Gostai angles of corium rounded, almost attaining posterior margin of connexival segment VI; suturai margins of membrane moderately convex. Ostiolar ruga attaining 2/3 of metapleural width. Abdominal venter convex. Medial spine of third abdominal segment short, laterally compressed, probably reaching hind coxae (thorax and abdómen displaced by pin).

Male genitália. Pygophore subtriangular; posterolateral angles projected posteriorly (Figs 6, 11, 16). Genital cup moderately excavated. Median projection of dorsal rim trapezoidal, slightly concave at apex; lateral third of dorsal rim not projected over genital cup (Fig. 6). Flaps of the infolding of ventral rim moderately bent over genital cup; ectal surface of flaps concave, lateral margins with irregularly spaced denticles, apical tooth present; mesial margin of flaps sinuous, moderately concave in posterior view (Figs 6, 11). Median excavation of,,„ ventral rim U-shaped in ventral view (Fig. 16). Depression of ventral wall of pygophore well developed, median carina conspicuous. Dorsal surface of segment X with well marked depression, delimited by keel-like carina (Figs 6, 11).

Type material. Holotype: Bolívia, La Paz, Maipiri , lo-, 10-16.VIII.1989, L.E.Pena coll. ( AMNH) .

Etymology. Named according the type locality.

Distribution. Bolivia.

Comments. The black spots on urosternites scarcely extending onto connexivum, the short abdominal spine and the colored band along body place this species near C. macdonaldi (ROLSTON) and C, wygodzinskyí (ROLSTON). Chinavia boliviensis nov.sp. can be distinguished from both by the yellow instead of orange (C. macdonaldi) or red (C. wygodzinskyi) band along the body margins, and by the spiracles placed on yellow calli. The humeri are right angular in C. boliviensis nov.sp. and C. macdonaldi, but produced laterad in C. wygodzinskyi.
