Oragua aurantimaculata sp. nov.

( Fig. 1 B, 3 A–L)

Type locality. Comunidade Lago Grande no Seringal do Recreio, Rio Gregório, Ipixuna, Amazonas State, Brazil.

Length. Males, 7.0– 8.25 mm. Females, 8.0– 8.5 mm.

External morphology. Head ( Fig. 3 A) with median length ranging from 0.3 to 0.6 times interocular width and from 0.2 to 0.4 transocular width; crown punctate. Ocelli ( Fig. 3 A) slightly anterad of line between anterior eye angles. Antennal ledges with anterior margin 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. 3 A) width less than transocular width of head; lateral margins slightly convergent anteriorly; surface very weakly punctate and weakly rugose transversally. Mesonotum ( Fig. 3 A) weakly punctate; not rugose. Forewings ( Fig. 1 B) with membrane weakly delimited, including apical cells 1, 2, 3, 4, and part of 5; with five apical cells (R1 present); base of fourth apical cell more proximal than base of third; clavus and corium with very shallow punctures. 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 B) dark brown dorsally; head and thorax beige ventrally. Crown ( Figs. 1 B, 3A) dark brown, with three large orange maculae, pair between each eye and adjacent ocellus and one median; apex beige to orange. Frons with paired lateral stripes dark brown, continuing the color of crown. Pronotum ( Figs. 1 B, 3A) with large lateral pale regions near anterior margin; paired longitudinally elongate orange maculae and small pale spots distributed over entire surface. Mesonotum ( Figs. 1 B, 3A) with four orange maculae, three close to anterior margin, which may be confluent, and one on apical half. Forewings ( Fig. 1 B) clavus usually with three distinct elongate maculae (holotype with maculae interrupted), anterior ones between anal veins, posterior one next to claval sutures, and small spots distributed along commissure, orange; corium with two distinct large maculae, basalmost round aligned with midlength of clavus and apicalmost elongate and transverse over anteapical cells, and irregular maculae distributed longitudinally near costal margin (may be confluent), orange; small pale spots distributed over most of basal two-thirds. Hindlegs with tibiae becoming darker gradually towards apex. Abdomen red.

Male genitalia. Pygofer ( Fig. 3 B) without processes; weakly produced; posterior margin slightly acute; macrosetae of different sizes on apical half. Valve ( Figs. 3 B, 3C) subtriangular. Subgenital plates ( Figs. 3 B, 3C) extending posteriorly almost to apex of pygofer; regular row of macrosetae along their extension and microsetae along lateral external margins. Styles ( Fig. 3 D) extend posteriorly slightly beyond apex of connective; preapical lobe weakly produced; microsetae on lateral surface; apex truncate, produced laterally. Connective ( Fig. 3 D) Tshaped, with stem much longer than arms. Aedeagus ( Figs. 3 E, 3F) with basidorsal and basiventral apodemes well developed, basiventral apodeme longer, both parallel in caudal view; shaft, in lateral view, elongate and curved posterodorsally, dorsal margin convex at midlength; pair of short lateral apical processes flattened and subtriangular, directed anteriorly. Membrane between aedeagus and anal tube with small and thin microsetae. Paraphyses ( Fig. 3 D) narrow, bifurcate on apical half; basal stalk widened at midlength; rami slender, each with width approximately half of the smallest width of the stalk; straight or slightly curved dorsally.

Female terminalia. Abdominal sternite VII ( Figs. 3 G, 3H) with posterior margin produced posteriorly; apex acute. Internal abdominal sternite VIII membranous. Valvifers I ( Fig. 3 I), in lateral view, higher than long; anterior margin with small concavity; posterior margin round. Valvulae I ( Fig. 3 I), in ventral view, with bases with inner margins thick continuing over a round anterior projection ( Fig. 3 J); shaft, in lateral view, with sculpturing strigate dorsally becoming concatenate apically and imbricate ventrally. Valvulae II ( Fig. 3 K), in lateral view, moderately broad and gradually tapered towards the apex, dorsal margin broadly arcuate; with approximately 48 subtriangular teeth with denticles on anterior and posterior margins ( Fig. 3 L); apex with anteapical denticles ventrally.

Etymology. The species epithet refers to the several distinct large orange dorsal maculae, even though these are shared by a few other Oragua species.

Notes. This species is very similar externally to O. elegantula and O. jau sp. nov. as they share the brown body with distinct orange maculae on the crown and forewings. However, the new species can be distinguished from the above-cited species as follows: aedeagus basiventral apodeme long; aedeagal shaft medially enlarged and with pair of short apical processes; and paraphyses with very slender parallel rami and without processes at base of rami. This new species can be distinguished from all other Oragua by the following set of characters: (1) body dark brown with distinct orange maculae, three on crown, two on pronotum, up to four on mesonotum, up to five on forewings in addition to irregular orange maculae distributed longitudinally near costal margin; (2) shaft of aedeagus, in lateral view, elongate and curved posterodorsally, enlarged at midlength, with pair of short lateral apical processes flattened and subtriangular, directed anteriorly; (3) paraphyses bifurcate with basal stalk widened at midlength and rami slender and parallel; and (4) bases of valvulae I of ovipositor, in ventral view, with inner corners projected anteriorly.
