Hypoxys servillei sp. nov.

( Figs 5A–B , 18A–F , 21B )

Material examined. Hඈඅඈඍඒඉൾ: J, BRAZIL: Gඈංගඌ: Jataí / 1904 / H. Donckier ( MNHN). Pൺඋൺඍඒඉൾ: BRAZIL: Mൺඍඈ Gඋඈඌඌඈ: ♀, Chapada dos Guimarães / 6.ii.1961 / Jan Bechyné ( MPEG); ♀, same place / 23.v.2011 / S. Klemp ( UFMT); same data holotype: ♀ ( MNHN).

Diagnosis. Antennae brown. Antennomere III longer than II. Pronotum with smoky stripe reaching posterior margin ( Fig. 5A ). Thoracic and abdominal pleurites and sternites with black spots ( Fig. 5B ). Anterior excavation of metasternal process harboring fourth and less than half of third rostral segment ( Fig. 18F ). Male genitalia. Pygophore ( Figs 18A–D ). Posterolateral angles developed, bent inwards, acuminate ( Fig. 18A ). Superior process of genital cup parallel to dorsal rim, long, almost reaching posterolateral angles, slightly concave medially; inner (proximal) part truncate, ventral angle with long digitiform process; outer (distal) part tongue-like and enlarged ( Figs 18C,D ). Paramere with two lobes; anterior lobe triangular, long, and directed to base of proctiger; lateral lobe short and rounded ( Figs 18C,D ). Proctiger with tufts of long setae along lateral excavation; posterior face bell-shaped ( Figs 18C,D ). Ventral rim with expansions developed, robust, distally rounded, ventrolateral side with broad striated excavation, dorsal side with brown spot; surpassing level of posterolateral angles ( Fig. 18B ). Female genitalia. Genital plates ( Fig. 18E ). Valvifers 8 posterior margin slightly concave, posterolateral angle dentiform and posteriorly directed, inner angle dentiform and projected to valvifers 9; imaginary line tangent to posterolateral angles almost reaching distal margin of valvifers 9; U-shaped excavation. Valvulae 8 visible. Apices of laterotergites 8 just passing 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.

Measurements (n = 4; mm). Total length 16.2–18.6; head length 1.7–1.9; head width 3.1–3.2; pronotum width 10.6–11.2; abdomen width 7.8–8.5; length of antennomeres: I – 0.8–1.0; II – 1.1–1.5; III – 1.4–3.5; IV – 3.6; V – missing; scutellum length 7.3–7.5; scutellum width 5.3–5.5; pronotum length 3.1–4.8.

Differential diagnosis. For the female genitalia see differential diagnosis of H. aspilogaster sp. nov.; for male genitalia see differential diagnosis of H. hyalinofasciatus sp. nov.

Etymology. Named after Jean Guillaume Audinet-Serville (1775–1858), the great French entomologist and coauthor of ‘ Histoire naturelle des insectes Hémiptères ’ with C. J.-B. Amyot.

Distribution ( Fig. 21B ). Brazil: Mato Grosso and Goiás.
