( Figs. 1 C, 4) Type-locality. Comunidade Ararão/Ararinha, Rio Padauari, Barcelos, Amazonas State, Brazil . Length. Males, 6.25–6.6 mm , Females, 6.25–6.5 mm . External morphology. Head ( Fig. 4 A) with median length from 0.3 to 0.5 times interocular width and from 0.2 to 0.3 times transocular width; crown punctate. Ocelli ( Fig. 4 A) on imaginary line between anterior eye angles. Antennal ledges with anterior margins vertical and slightly concave. Frons and upper portion of clypeus weakly flattened medially. Clypeus with lower portion weakly oblique in relation to frons. Epistomal suture complete. Pronotum ( Fig. 4 A) width less than transocular width; lateral margins slightly convergent anteriorly; surface punctate and not rugose. Mesonotum ( Fig. 4 A) punctate and not rugose. Forewings ( Fig. 1 C) with membrane weakly delimited, including only the first apical cell; 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 the generic description. Coloration. Body ( Fig. 1 C) black dorsally and dark brown ventrally. Crown ( Figs. 1 C, 4A) with paired orange maculae, each between the eye and adjacent ocellus, extending to antennal ledges; apex with round orange macula extending to frons. Frons black, with round orange macula above epistomal suture. Clypeus dark brown. Pronotum ( Figs. 1 C, 4A) with paired transversally elongate orange maculae at midlength which can be continuous. Mesonotum ( Figs. 1 C, 4A) apical half orange. Forewings ( Figs. 1 C) with small yellow spots usually distributed forming two transcommissural stripes; clavus with basal orange macula; corium with two orange maculae, basalmost aligned with midlength of clavus and apicalmost over anteapical cells. Paratype from Par has orange maculae faded, being yellowish-white. Male genitalia. Pygofer ( Fig. 4 B) without processes; weakly produced; posterior margin truncate; macrosetae of different sizes on apical half. Valve ( Fig. 4 C) subtrangular. Subgenital plates ( Figs. 4 B, 4C) short, not attaining apex of pygofer; regular row of macrosetae along their extension and microsetae along lateral external margins. Styles ( Fig. 4 D) extending posteriorly beyond apex of connective; preapical lobe inconspicuous; preapical microsetae originating on ventral surface; apex acute and unciform, curved inwards. Connective ( Fig. 4 D) Yshaped. Aedeagus ( Figs. 4 E, 4F) with membranous basidorsal and without basiventral apodemes; shaft slender and curved dorsally in lateral view, without processes; with pair of elongate basiventral processes, each approximately twice the length of shaft with basal portion robust, curved dorsally and narrowing towards the apex in lateral view, processes divergent in caudal view. Membrane between aedeagus and anal tube with thin and elongate setae ( Fig. 4 E). Paraphyses absent. Female terminalia. Abdominal sternite VII ( Figs. 4 G, 4H) with posterior margin slightly produced and apex slightly acute. Internal abdominal sternite VIII membranous. Valvifers I ( Fig. 4 I), in lateral view, with anterior margin slightly concave and posterior margin produced posteriorly. Valvulae I ( Fig. 4 I), in ventral view, bases with internal margin thick longitudinally and anterior margin round ( Fig. 4 J); shaft, in lateral view, with sculpturing concatenate dorsally and ventrally ( Fig. 4 K), ventral membrane with longitudinal striae that become more elongate and closer to each other on median portion ( Fig. 4 L). Valvulae II ( Fig. 4 M), in lateral view, moderately borad and gradually tapered towards the apex, with ventral margin broadly arcuate, with 17 to 20 subtriangular teeth with denticles only on posterior margin ( Fig. 4 N); apex with ventral anteapical denticles absent ( Fig. 4 O). Etymology. The species epithet refers to the beautiful habitus of this species. Notes. Oragua bella resembles O. variolosa because of the dark body with large orange maculae on the crown, pronotum, mesonotum, and forewings and small yellow spots on the forewings. However, the new species can be distinguished by the pronotum with only a pair of transversely elongate orange maculae and two orange maculae on corium. This new species can be distinguished from all other Oragua by the following set of characters: (1) body black with crown with paired orange maculae close to eyes and apex orange, with paired transversely elongate orange maculae on pronotum, mesonotum apical half orange, and three orange maculae on forewings, one at base of clavus and two on corium, and small yellow spots distributed forming two transcommissural stripes on forewings; (2) style with apex unciform curved inwards; (3) aedeagus with paired elongate basiventral processes, divergent in caudal view; (4) paraphyses absent; and (5) shaft of valvulae I of ovipositor with sculpturing concatenate dorsally and ventrally.
