Hypoxys balteatus species group

Diagnosis. Pronotum with posterior stripe, smoky brown to black, with black punctures, sometimes punctures on small dark spots ( Figs 5A,C,E ); posterolateral angles somewhat prominent, smaller than eye width ( Fig. 1A ). Anterolateral margin of pronotum yellow. Anterior half of scutellum with large, sparse punctures on dark spots ( Figs 3A,C,E ). Connexivum uniformly green, without dark spots ( Figs 5A,E ), except for H. nigroantennatus sp. nov. and H. bergrothi sp. nov. Body ventrally green, yellow medially, sometimes with narrow yellow transverse stripes; brown to black round spots on thorax (meso- and metapleura) and pseudosutures ( Figs 5B,D ), except for H. immaculatus sp. nov. ( Fig. 4B ) and H. aspilogaster sp. nov. ( Fig. 1B ). Parameres almost straight in dorsal view, but never strongly curved laterally like in other species of Hypoxys ( Fig. 7A – green dash). Ventral rim of pygophore with expansions ( Fig. 6B ) developed, acuminate, and triangular in cross section ( Figs 16B–D ); expansions shallowly excavated

ventrolaterally ( Fig. 19C ), except for H. santarensis sp. nov. Valvifers 8 with distal margin projected caudally, posterolateral angle armed with small tooth projected over laterotergites 9 ( Fig. 16E ).

Redescription. Head. Mandibular plates and clypeus without black marks (except H. nigroantennatus sp. nov.). Thorax. Cicatrices of pronotum smooth. Scutellum with rare, minute punctures apically, some species have spots that resemble punctuation ( Figs 1C , 2A ). Evaporatorium and ventral surface of thorax concolorous.Abdomen. Connexivum with shallow punctures, punctures concolorous with abdomen. Distal half or less of segment VII black. Without dark transversal stripes ventrally. Male genitalia ( Figs 6A–D ). Bottom of ventral rim excavation with tiny fold. Female genitalia ( Fig. 6E ). Distal margin of laterotergites 8 and 9 black.
