Braunus gibbus Garbelotto & Barão sp. nov.

( Figures 5 View FIGURES 1 – 11 , 44–47 View FIGURES 44 – 47 , 78 View FIGURES 78 – 82 )

Material examined. Holotype ♀, BOLIVIA, Depart. Santa Cruz, Prov. Caballero, PN Amboro , 17°50.8’S 64°23.23’W, 2050 m, 15–21.X.2001, S. Spector & J. Ledezma leg., general hand collecting, COBIMI 0 0 0 3905 ( AMNH) GoogleMaps .

Diagnosis. Head yellowish dorsally. Each anterior angle of pronotum with an acute process; each anterolateral margin with three small tubercles; posterior lobe of pronotum twice as long as the anterior lobe; humeral angles directed anterolaterad ( Fig. 5 View FIGURES 1 – 11 ). Apex of hemelytral radial vein calloused; corium reaching abdominal segment VI. Abdomen dark brown with 1+1 yellowish lines ventrally. Female genitalia: posterior margin of each gonocoxite 8 concave; posterior margin of each laterotergite 8 acute; laterotergites 9 triangular ( Figs 46–47 View FIGURES 44 – 47 ).

Description. Body color mottled dark-yellowish and brown, predominantly yellowish dorsally and abdomen dark brown with 1+1 yellowish lines ventrally; head yellowish; labial apex brown ( Figs 44–45 View FIGURES 44 – 47 ). Mandibular plates longer than clypeus. Proportion of antennal segments: I=II<III=IV<V. Labial apex attaining abdominal sternite III. Processes at anterior angles of pronotum each directed anteriorly, acute apically, barely reaching posterior margin of each compound eye. Anterolateral margins of pronotum each with 3+3 little-produced, finger-like tubercles; each humeral angle bilobed apically, with two processes anteriorly and one process posterolaterally; posterolateral margins sinuate; pronotal disc calloused between cicatrices ( Fig. 5 View FIGURES 1 – 11 ). Scutellum reaching posterior margin of abdominal segment V; lateral margins of scutellum each with shallow excavation; scutellum swollen longitudinally, medially; postfrenal lobe about 1/2 of length of frenal lobe. Hemelytral corium reaching posterior margin of abdominal segment VI; membrane slightly surpassing abdominal apex, veins coarse and reticulate. Hind wings reduced. Mesosternum with median carina slightly elevated. Metasternum with shallow median furrow.

Female genitalia. Gonocoxites 8 longer than wide; each sutural margin parallel and juxtaposed at 1/3 basal portion, widely separated and sinuous on remaining 2/3; posterior margins concave ( Figs 46–47 View FIGURES 44 – 47 ; gc8). Gonapophyses 8 visible, subtriangular, with median carina ( Figs 46–47 View FIGURES 44 – 47 ; g8). Laterotergites 8 triangular, longer than wide; each posterior margin acute, reaching to posterior margins of tergite 8 ( Figs 46–47 View FIGURES 44 – 47 ; la8). Gonocoxites 9 trapezoidal, with median sulcus ( Figs 46–47 View FIGURES 44 – 47 ; gc9). Each laterotergites 9 triangular, strongly depressed basally, apices rounded, reaching to posterior margin of tergite 8 ( Figs 46–47 View FIGURES 44 – 47 ; la9). Segment X subtriangular ( Figs 46–47 View FIGURES 44 – 47 ; X).

Measurements. Total length, 10.0; head length, 2.0; head width, 1.4; length of pronotum, 2.2; width of pronotum at base, 5.1; maximum width of pronotum at humeral angle, 7.0; length of scutellum, 3.4; width of scutellum, 3.3; width of abdomen across third segment, 5.4.

Etymology. gibbus (m.), from the Latin, meaning humped, in reference to the enlarged pronotum.

Distribution. Bolivia (Santa Cruz) ( Fig. 78 View FIGURES 78 – 82 ).

Remarks. Male unknown.
