Diagnosis. Antennae reddish ( Fig. 2C ). Antennomere III longer than II. Pronotum with smoky stripe reaching posterior margin. Thoracic and abdominal pleurites and sternites with black spots ( Fig. 2D ). Anterior excavation of metasternal process harboring fourth and almost whole third rostral segment ( Fig. 10F ). Male genitalia. Pygophore ( Figs 10A–D ). Posterolateral angles developed, bent inwards ( Fig. 10A ). Superior process of genital cup bilobate, short and close to proctiger; inner and outer ends projected ventrally ( Figs 10C,D ). Paramere with two lobes; anterior lobe developed, triangular and directed to base of proctiger; lateral lobe large and rounded ( Figs 10C,D ). Proctiger with scattered setae on lateral excavation; posterior face subtriangular ( Figs 10A–C ). Ventral rim with expansions acuminate, ventrolateral side gently impressed, dorsal side with brown spot on margin; barely surpassing level of posterolateral angles ( Fig. 10B ). Female genitalia. Genital plates ( Fig. 10E ). Valvifers 8 posterior margin with posterolateral angles dentiform and short, inner angles dentiform, reaching valvifers 9; imaginary line tangent to posterolateral angles not reaching medial line of valvifers 9; excavation widely U-shaped. Valvulae 8 visible. Apices of laterotergites 8 clearly above level of apices of abdominal segment VII. Laterotergites 9 clearly surpassing band connecting laterotergites 8; apices clearly below imaginary line tangent to apices of abdominal segment VII.

Measurements (n = 4; mm). Total length 17.0–18.2; head length 1.6–1.8; head width 3.2–3.5; pronotum width 10.2–11.9; abdomen width 8.2–9.0; length of antennomeres: I – 0.8–0.9; II – 1.4–1.6; III – 1.5–1.8; IV – 1.8–3.5; V – 3.3–4.0; scutellum length 7.4–8.4; scutellum width 5.7–6.0; pronotum length 3.1–3.5.

Differential diagnosis. See differential diagnosis of H. balteatus .

Etymology. Named after Gustav Breddin (1864–1909), the German entomologist that made the most important contribution to the knowledge of Hypoxys in the early 20 th century. Distribution ( Fig. 21A ). Bolivia: Santa Cruz and San Carlos.
