( Figs. 1 E, 6 A–G) Type locality. Reserva do km 41, Forest Reserve of the Biological Dynamics of Forest Fragments Project ( BDFFP ), Rio Preto da Eva, Amazonas State, Brazil . Size. Male, 7.13 mm . External morphology. Head ( Fig. 6 A) with median length half of interocular and three-tenths transocular width; crown punctate. Ocelli ( Fig. 6 A) located on imaginary line between anterior eye angles. Antennal ledges with anterior margin oblique and slightly convex. Frons not flattened medially. Clypeus with lower portion oblique in relation to frons. Epistomal suture complete. Pronotum ( Fig. 6 A) width less than transocular width; lateral margins slightly convergent anteriorly; surface punctate and not rugose. Mesonotum ( Fig. 6 A) punctate and not rugose. Forewings ( Fig. 1 E) without membrane delimited; with five apical cells (R1 present); base of fourth apical cell slightly more proximally 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 (left posterior tarsi missing). Other characters as in generic description. Coloration. Body ( Fig. 1 E) brown dorsally and ventrally. Crown ( Figs. 1 E, 6A) with pair of lateral pale maculae between each eye and adjacent ocellus and pair of pale triangular maculae on apex continuing to frons. Frons with median V-shaped pale macula. Pronotum ( Figs. 1 E, 6A) with three pale maculae, one small on anterior margin and paired transverse lateral ones at midlength. Mesonotum ( Figs. 1 E, 6A) with apical half pale. Forewings ( Fig. 1 E) clavus with one large basal pale macula and small pale spots over posterior three-fourths coalescing near apex. Corium with two pale maculae, basalmost aligned with midlength of clavus and apicalmost elongate and transverse over anteapical cells, and two groups of few small pale spots that coalesce, one close to base and another close to costal margin. Male genitalia. Pygofer ( Fig. 6 B) without processes; weakly produced; posterior margin round; macrosetae of different sizes on posterior two-thirds. Valve ( Figs. 6 B, 6C) subrectangular. Subgenital plates ( Figs. 6 B, 6C) not extending to midlength of pygofer; regular row of macrosetae along their extension and microsetae along lateral external margins. Styles ( Fig. 6 D) extending beyond the apex of connective; preapical lobe weakly produced; preapical microsetae originating on ventral surface; apex truncate, not laterally produced. Connective ( Fig. 6 D) Tshaped. Aedeagus ( Figs. 6 E, 6F) with basidorsal apodemes developed, slender, parallel in caudal view, and without basiventral apodemes; shaft, in lateral view, long and slender; with pair of lateral apical processes. Paraphyses ( Figs. 6 D, 6G) rami separate at base (pair of paraphysis), basal connection of rami membranous; rami long, basal third wide, apical two-thirds slender, apical third bifurcate and curved dorsally. Female terminalia. Female unknown. Etymology. The species epithet refers to the more slender aedeagus shaft of this species, compared to that of the similar O. galerula . N otes. This species is similar to O. galerula , as they share the same pattern of maculae on the crown, pronotum, and mesonotum; short subgenital plates; paired paraphysis; and general shape of the styles, connective, and aedeagus. However, the new species can be distinguished by the brown ground color, and not black as in O. galerula ; absence of two maculae near the median line just before the posterior margin of the pronotum; styles extending to a greater distance beyond the apex of the connective; aedeagus shaft more slender; and apices of rami of paraphyses bifurcate and not truncate and serrate. O. gracilenta sp. nov. can be distinguished from all other Oragua by the following set of characters: (1) body brown with pale maculae, four on crown, three on pronotum, and one on mesonotum; (2) aedeagus with basidorsal apodemes developed, slender, parallel in caudal view, and without basiventral apodemes; (3) aedeagus shaft long and slender, bifurcate at apex; and (4) paraphysis separate at base, with rami long, wide near base and bifurcate apically.
