description: <i>Pentatomiana beckerae</i> sp. nov. <b>Figs 1-7</b> Etymology. In honor to Dr. Miriam Becker, for her contribution to the knowledge of Neotropical pentatomids. Male (Fig. 1). Total length 9.69-9.85; abdominal width 6.35-6.68; head length 2.56, width 2.80-2.88; interocular distance 1.84-2.00; anteocular length 1.36-1.40; ocular width 0.48- 0.56; antennal segments I – 0.62-0.70, II – 0.68-0.82, III – 0.95- 1.01, IV – 1.05, V – lost; pronotal length 2.16-2.32, width 5.76- 6.08; scutellum length 3.68-4.00, width 3.52-3.76. General color castaneous, with dark-brown to black punctures. Head slightly wider than long; punctures densely distributed, except on 1 + 1 small elliptical areas, parallel and innerly to basal 2/3 of eyes. Antennal segments progressively longer toward apex. Ocelli reddish. Pronotum surface strongly rug- ose. Pronotal disc with 1 + 1 conspicuous, conical tubercles, just behind cicatrices; basal fourth limited by a transversal, subcalosed, yellowish carina, extending along pronotal width. Longitudinally, a median, less conspicuous carina, evanescent toward the basal third of scutellum. Anterior margin excavated, rectilinear adjacent to interocular area, and strongly elevated toward eyes. Anterior angles acute, toothed. Anterolateral margins concave, with several tubercles; humeral angles moderately projected laterad. Posterior margin subrectilinear, slightly concave. Scutellum surface rugose, with 1 + 1 shallow foveae at basal angles and 1 + 1 inner, conical tubercles. Scutellar disc elevated in a Y-like, slightly tumid area; apical margin with 1 + 1 tubercles. Corium more densely punctured at clavus and along costal margin; a conical tubercle at apex of radius vein; apical angle of corium slightly convex. Brachypterous, membrane of hemelytra, in repose, reduced to a narrow fringe, not surpassing apex of scutellum; in unfolded wing, membrane narrowly projected at inner angle (Fig. 2); hind wings absent. Legs ocraceous, with dark-brown spots and punctures, larger on femora. Apical angles of connexivum obtusely produced. Abdomen ventrally yellowish-castaneous, with dark-castaneous to black punctures coarsely and irregularly distributed at laterals. Medially, a dark-castaneous, shiny area on sternites III to VII, with sparse punctures. Spiracles dark-castaneous to black. Genitalia (Figs 3-5). Dorsal rim of pygophore (dr) strongly convex on median third. Genital cup (gcp) processes well visible, turned toward parameres (pa). Xsegment trapezoidal, apex strongly turned ventrad, with about half of base width. Parameres F-like, projections directed to genital cup process. Ventral rim (vr) concave at middle. Female. Total length 11.19; abdominal width 7.85; head length 2.60, width 3.04; interocular distance 2.12; anteocular length 1.44; ocular width 0.56; antennal segments I – 0.74, II – 0.86, III – 0.97, IV – 1.13, V – 1.40; pronotal length 2.88, width 7.20; scutellar length 4.64, width 4.64. General morphology as the male, except for: hemelytral membrane and hind wings fully-developed; membrane of hemelytra with a few veins forming one or two cells; shiny area of abdominal venter over median third of sternites III to anterior half of VI. Genitalia (Figs 6-7). Posterior margin of gonocoxites 8 (gc8) slightly concave in front of laterotergites 9 (la9); sutural margins parallel; sutural angles divergent. Laterotergites 8 (la8) with acute apex. Laterotergites 9 rounded at apex, a little longer than laterotergites 8, surpassing transversal band linking them dorsally.
