Oragua schwertneri sp. nov.

( Figs. 1 G, 8 A–G)

Type-locality. Comunidade Acuquaia, Rio Padauari, Barcelos, Amazonas State, Brazil.

Length. Male 7.25 mm.

External morphology. Head ( Fig. 8 A) with median length 0.4 times interocular width and 0.3 transocular width; crown punctate. Ocelli ( Fig. 8 A) located on imaginary line between anterior eye angles. Antennal ledges with anterior margins vertical and concave. Frons and upper portion of clypeus weakly flattened medially. Clypeus with lower portion oblique in relation to frons. Epistomal suture complete. Pronotum ( Fig. 8 A) with width less than transocular width; lateral margins slightly convergent anteriorly; surface punctate and not rugose. Mesonotum ( Fig. 8 A) punctate and not rugose. Forewings ( Fig. 1 G) with membrane weakly delimited, including apical cells 1, 2, 3, 4, and half of 5; with five apical cells (R1 present); base of fourth more proximal than base of third; clavus and corium punctate. Hindlegs with femoral setal formula 2:1:1; first tarsomere with length greater than combined length of two more distal tarsomeres; with two longitudinal regular rows of small setae on plantar surface. Other characters as in generic description.

Coloration. Body ( Fig. 1 G) dark brown dorsally and beige ventrally. Crown ( Figs. 1 G, 8A) with frontal portion beige; irregular transversally elongate maculae between ocelli and apical maculae arcuate, continuing as paired longitudinal stripes on median portion of frons, yellowish-orange. Antennal ledges orange. Pronotum ( Figs. 1 G, 8A) with two large lateral anterior maculae yellow becoming more orange laterally. Forewings ( Fig. 1 G) with small pale maculae on anterior half of costal margin.

Male genitalia. Pygofer ( Fig. 8 B) without processes; weakly produced; apex truncate and serrate, curved inwards ( Fig. 8 C); macrosetae of different sizes on apical half. Valve ( Fig. 8 D) transverse with lateral margins produced. Subgenital plates ( Figs. 8 B, 8D) not attaining apex of pygofer; regular row of macrosetae along their extension and microsetae along lateral external margins. Styles ( Fig. 8 E) extending slightly beyond the apex of connective; preapical lobe inconspicuous; preapical microsetae originating on ventral surface; apex truncate, produced laterally. Connective ( Fig. 8 E) Y-shaped. Aedeagus ( Figs. 8 F, 8G) with basidorsal and basiventral apodemes well developed, basidorsal one parallel in caudal view; shaft, in lateral view, weakly curved dorsally, slightly thicker at midlength, with pair of short caudally divergent lateral apical processes; with paired slender basiventral processes, approximately same length as shaft; curved dorsally. Membrane between aedeagus and anal tube with short setae ( Fig. 8 F). Paraphyses absent.

Female terminalia. Female unknown.

Etymology. This species is named after Dr. Cristiano Schwertner (Universidade Federal de São Paulo), stink bug specialist and collector of the single specimen found in this locality.

Notes. Oragua schwertneri is similar to O. insipida as they share the dark body with orange and yellow maculae on the crown and pronotum and small yellow maculae on the corium. However, the new species can be distinguished by the smaller maculae on the crown and pronotum; yellow maculae on the corium only along anterior half of costal margin; aedeagus with paired slender basiventral processes; shaft with paired short lateral apical processes; and absence of paraphyses. This species can be distinguished from all other Oragua by the following set of characters: (1) body dark with irregular maculae transversely elongate on crown and pronotum; (2) aedeagus with paired slender basiventral processes and shaft with paired short and divergent lateral apical processes; and (3) paraphyses absent.
