( Figs 2A–B , 9A–B , 21B ) Material examined. Hඈඅඈඍඒඉൾ: FRENCH GUIANA : Sൺංඇඍ - Eඅංൾ: Inselberg Haute - Koursibo / Savane - roche / 26.x.2013 ( MNHN ). Pൺඋൺ- ඍඒඉൾ: VENEZUELA : Aආൺඓඈඇൺඌ: ♀ , Mouth Cunucuna / 6.vi.1950 / J. Maldonado Capriles col. ( USNM ). Diagnosis. Antennae brown. Antennomere II longer than III. Pronotum with smoky stripe not reaching posterior mar- gin. Thoracic and abdominal pleurites and sternites with black spots ( Fig. 2B ). Anterior excavation of metasternal process harboring fourth, third and less than half of second rostral segment ( Fig. 9B ). Female genitalia. Genital plates ( Fig. 9A ). Valvifers 8 posterior margin with posterolateral angles blunt, inner angles short, rounded and directed to valvifers 9; imaginary line tangent to posterolateral angle almost reaching distal margin of valvifers 9; inner margin not projected posteriorly; excavation U-shaped. Valvulae 8 visible. Apices of laterotergites 8 clearly above level of apices of abdominal segment VII. Laterotergites 9 surpassing band connecting laterotergites 8; apices clearly below imaginary line tangent to apices of abdominal segment VII. Male genitalia. Unknown. Measurements (n = 2; holotype first; mm). Total length 17.2 / 18.3; head length 1.7 /2.0; head width 3.5 / 3.5 (no span); pronotum width 10.3 / 11.5; abdomen width 8.7 / 10.0; length of antennomeres: I – 0.9 / 1.0; II – 1.6 / 1.6; III – 1.5 / 1.5 (no span); IV – 4.2 / 4.4; V – missing; scutellum length 7.9 / 7.9 (no span); scutellum width 5.7 / 6.5; pronotum length 3.4 / 3.5. Differential diagnosis. Hypoxys bergrothi sp. nov. is the only species that presents valvifers 8 overlapping lateral margin of valvifers 9, leaving the excavation narrow, as narrow as segment X. The other species all have the excavation wider than segment X. Etymology. Named after Ernst Evald Bergroth (1857– 1925), the Finnish entomologist that made significant contributions to the study of Pentatomidae . Distribution ( Fig. 21B ).
