Treatment

Oragua alerochae View in CoL sp. nov.

( Figs. 1 View FIGURE 1 A, 2 A–O)

Type-locality. Comunidade Paxiúba, Rio Abacaxis, Borba, Amazonas State, Brazil.

Length. Males, 8.0– 8.5 mm, Females, 7.5–8.25 mm.

External morphology. Head ( Fig. 1 View FIGURE 1 A and 2A) 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. 2 View FIGURE 2 A) located slightly anterad of imaginary line between anterior eye angles. Antennal ledges with anterior margin vertical and straight. Frons not flattened medially. Clypeus with lower portion continuing profile of frons. Epistomal suture complete. Pronotum ( Fig. 1 View FIGURE 1 A and 2A) width less than transocular width; lateral margins slightly convergent anteriorly; surface with small punctuations and weakly rugose transversally on posterior portion. Mesonotum ( Fig. 2 View FIGURE 2 A) weakly punctate and not rugose. Forewings ( Fig. 1 View FIGURE 1 A) without membrane delimited; with five apical cells (R1 present); base of fourth apical cell more proximal than base of third; clavus and basal three quarters of the corium weakly 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 View FIGURE 1 A) brown dorsally and dark brown ventrally. Crown ( Figs. 1 View FIGURE 1 A, 2A) with two lateral dark brown maculae in front of ocelli continuous with frons. Pronotum ( Fig. 1 View FIGURE 1 A, 2A) with darker irregular areas. Median apical maculae on crown, maculae on antennal ledges, and two thin transcommissural transverse stripes on forewings, ivory. Forewings ( Fig. 1 View FIGURE 1 A) basal stripe restricted to clavus, extending over apex of mesonotum (part over mesonotum darker; apical stripe reaches costal margins, extending over apex of clavus; both stripes are lined by dark brown stripes.

Male genitalia. Pygofer ( Fig. 2 View FIGURE 2 B) without processes; weakly produced; posterior margin round; macrosetae of different sizes on apical half. Valve ( Fig. 2 View FIGURE 2 C) subtriangular. Subgenital plate, in lateral view, ( Fig. 2 View FIGURE 2 B) not extending to apex of pygofer; with irregular longitudinal lateral row of macrosetae and microsetae along the lateral external margins. Style ( Fig. 2 View FIGURE 2 D), in dorsal view, not attaining posteriorly apex of connective; preapical lobe weakly produced; preapical microsetae originating on ventral surface; apex acute and unciform. Connective ( Fig. 2 View FIGURE 2 D) T-shaped. Aedeagus ( Fig. 2 View FIGURE 2 F) with basidorsal apodemes robust and developed, parallel in caudal view; basiventral apodemes absent; shaft, in lateral view, slender, becoming gradually thinner towards apex, apical half curved ventrally; pair of apical lateral processes thin and elongate, approximately one third shaft length. Membrane between aedeagus and anal tube with small and robust setae. Paraphyses ( Figs. 2 View FIGURE 2 D, 2F) bifurcate at base; rami around two times longer than connective, tapering towards apex, apices curved dorsally.

Female terminalia. Abdominal sternite VII ( Figs. 2 View FIGURE 2 G, H) with posterior margin produced posteriorly; apex acute. Internal abdominal sternite VIII ( Fig. 2 View FIGURE 2 I) with three sclerotized areas, anterior one transversely elongate and with three lobes and posterior pair round and transversely rugose. Valvifer I, in lateral view, ( Fig. 2 View FIGURE 2 J) as high as long, with anterior margin straight and posterior margin rounded. Valvula I, in ventral view, ( Fig. 2 View FIGURE 2 k) base with anterior margin with round internal anterior projection; shaft, in lateral view, (fig. 2J) with sculpturing strigate dorsally becoming concatenate towards apex, and imbricate ventrally, ( Fig. 2 View FIGURE 2 L). Valvula II ( Fig. 2 View FIGURE 2 M), in lateral view, moderately broad, gradually tapered, dorsal margin arcuate, with approximately 48 subtriangular dorsal teeth, each with several smaller denticles ( Fig. 2 View FIGURE 2 N); ventral anteapical denticles present ( Fig. 2 View FIGURE 2 O).

Etymology. This species is named after the collector of the holotype, Dr. Rosaly Ale-Rocha (INPA), Diptera taxonomist and great enthusiast of leafhopper diversity.

Notes. The external coloration of O. alerochae is similar to O. bifasciata , as they share the dorsally brown body with two ivory transverse stripes on the forewings. However, the new species can be distinguished by the lack of a pale triangular macula on the anterior margin of the pronotum; its lighter-colored forewings and thinner stripes which are bordered by dark brown; more strongly curved aedeagus, with longer apical processes; and the curved apices of the paraphyses. This new species can be distinguished from all other Oragua by the following combination of characters: (1) body dark with two ivory stripes across the forewings; (2) shaft of aedeagus slender with apical portion curved ventrally and a pair of long slender lateral apical processes approximately one third the length of the shaft; and (3) paraphyses bifurcate at the base, with rami around two times longer than connective and curved apically.
