Oragua jau sp. nov.

( Figs. 1 F, 7 A–N)

Type-locality. Comunidade Seringalzinho, Parque Nacional do Jaú , Novo Airão, Amazonas State, Brazil. Length. Males, 6.0– 6.75 mm; females, 7.0– 7.5 mm.

External morphology. Head ( Fig. 7 A) with median length ranging from 0.3 to 0.6 times interocular width and from 0.2 to 0.4 transocular width; crown with small punctuations. Ocelli ( Fig. 7 A) located slightly anterad of imaginary line between anterior eye angles. Antennal ledges with anterior margins vertical and slightly concave. Frons and upper portion of the clypeus weakly flattened medially. Clypeus with lower portion weakly oblique in relation to frons. Epistomal suture complete. Pronotum ( Fig. 7 A) width less than transocular width; lateral margins slightly convergent anteriorly; surface with small punctuations and weakly rugose transversally on posterior portion. Mesonotum ( Fig. 7 A) weakly punctate and not rugose. Forewings ( Fig. 1 F) with membrane weakly delimited including apical cells 1, 3, 4, and part of 5; with five apical cells (R1 present); base of the fourth more proximal than base of third; clavus and basal half of corium weakly punctate; forewings of female in rest position extending posteriorly beyond the apex of ovipositor. 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 F) dark brown dorsally and beige ventrally. Crown ( Figs. 1 F, 7A) dark brown, with three large orange maculae, pair between each eye and adjacent ocellus and one median; apex beige, yellow or orange. Frons with paired lateral stripes dark brown, continuing the color of crown. Pronotum ( Figs. 1 F, 7A) with large lateral pale regions near anterior margin; paired longitudinally elongate orange maculae and small pale spots distributed over entire surface. Mesonotum ( Figs. 1 F, 7A) with two orange maculae, one close to anterior margin and one on apical half. Forewings ( Fig. 1 F) clavus pale (due to the confluence of small spots); with three distinct maculae on clavus, anterior ones between anal veins (middle one may be interrupted), posterior one next to claval sutures, orange with dark brown outline; 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. Hindlegs with tibiae becoming darker gradually towards the apex. Abdominal terga red.

Male genitalia. Pygofer ( Fig. 7 B) without processes; weakly produced; posterior margin slightly acute; macrosetae of different sizes on apical half. Valve ( Fig. 7 C) subtriangular. Subgenital plates ( Fig. 7 C) extending posteriorly to apex of pygofer; irregular row of macrosetae along their extension and microsetae along lateral external margins. Styles ( Fig. 7 D) extending posteriorly beyond apex of connective; preapical lobe weakly produced; preapical microsetae originating on ventral surface; apex truncate, produced laterally. Connective ( Fig. 7 D) Y-shaped, with arms weakly oblique. Aedeagus ( Fig. 7 E G) with basidorsal and basiventral apodemes robust and well developed, parallel in caudal view ( Fig. 7 G); shaft, in lateral view, directed posterodorsally, long, and slender; pair of lateral apical processes short. Membrane between aedeagus and anal tube with setae short and robust. Paraphyses ( Fig. 7 D 7E) narrow, bifurcate at 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 ( Fig. 7 H, 7I) with posterior margin produced; apex acute. Internal abdominal sternite VIII membranous. Valvifers I, in lateral view, ( Fig. 7 J) higher than longer, with anterior margin straight and posterior margin round. Valvulae I, in ventral view, with bases with inner margins thick continuing over a round anterior projection ( Fig. 7 K); shaft, in lateral view, with sculpturing strigate dorsally becoming concatenate towards the apex, and imbricate ventrally. Valvulae II ( Fig. 7 L), in lateral view, moderately broad and slightly tapering towards the apex, dorsal margin slightly arcuate, with approximately 51 subtriangular teeth with denticles on anterior and posterior margins ( Fig. 7 M); apex with ventral anteapical denticles present ( Fig. 7 N).

Etymology. This species is named after River Ja, from which the Parque Nacional Ja received its name. Ja is also one of the largest catfishes in the Amazon basin.

Notes. Oragua jau is similar in coloration to O. elegantula as they share the brown body with three orange maculae on the crown and orange maculae on the forewings. However, the new species can be distinguished by the styles extending beyond the apex of connective and aedeagus with basidorsal apodemes and short lateral apical processes on shaft. This new species can be distinguished from all other Oragua by the following set of characters: (1) body dark brown with large orange maculae, three on crown, two on pronotum, two on mesonotum and up to nine maculae on forewings; (2) styles extending beyond apex of connective; and (3) aedeagus with basidorsal and basiventral apodemes and shaft directed posterodorsally, elongate and slender, with pair of short lateral apical processes.
