Diagnosis

Green sharpshooters; male pygofer with apex acute; aedeagus with pair of apical wingshaped processes and two ventral separate dentiform processes: an apical and a subapical one; paraphyses with pair of short rami with acute apices.

Comment

The presence of the subapical dentiform ventral process of the aedeagus is a homoplastic autapomorphy of S. subolivacea shared with S. osteiphera sp. nov., S. amazonensis sp. nov. and S. oglobini ( Leal 2014) .

Length. Males, 5.2–5.6 mm; females, 5.4–6.0 mm.

External morphology

Head ( Figure 2A View Figure 2 ) moderately produced anteriorly, median length of crown about 1/2 interocular width and 1/3 transocular width; anterior margin broadly rounded in dorsal view; ocelli located behind anterior eye angles, each closer to adjacent eye angle than to median line of crown, situated at pair of slight concavities. Pronotum ( Figure 2A View Figure 2 ) with width approximately equal to transocular width, lateral margins convergent anteriorly, dorsopleural carinae complete and oblique, disc smooth; mesonotum with scutellum not striate. Fore wings ( Figure 2B View Figure 2 ) opaque; membrane including all of apical cells, extending anteriorly along costal margin as far as basal half of wing. Hind legs with length of first tarsomere greater than combined length of two more distal ones.

Coloration

Background colour of crown, anterior third of pronotum, and mesonotum yellow, rest of dorsum dark green ( Figure 2A, B View Figure 2 ). Crown ( Figure 2A View Figure 2 ) with green round maculae including ocelli, Y-shaped brown macula on median portion. Pronotum ( Figure 2A View Figure 2 ) with black transverse macula with broadened ends on anterior third. Mesonotum ( Figure 2A View Figure 2 ) with pair of black maculae on basal angles, partially concealed by pronotum. Fore wings ( Figure 2B View Figure 2 ) with longitudinal veins dark in some specimens. Face with frons greenishyellow, mesosternum black, legs and ventral portion of abdomen pale yellow.

Male genitalia

Pygofer ( Figure 2C View Figure 2 ), in lateral view, moderately produced posteriorly; dorsal margin approximately rectilinear, oblique; posteroventral margin broadly convex; apex acute; macrosetae more numerous near apex, gradually scattered along margins; slender process arising from ventral margin, extending posterodorsally as far as pygofer apex, internal and parallel to posteroventral margin. Subgenital plates ( Figure 2D View Figure 2 ) subtriangular, not extending as far posteriorly as apex of pygofer, gradually tapered towards apex; macrosetae uniseriate along outer margin. Styles ( Figure 2E View Figure 2 ) slender, without preapical lobe, not extending as far posteriorly as apex of connective, curved outwards. Connective ( Figure 2E View Figure 2 ) Y-shaped. Aedeagus ( Figure 2F View Figure 2 ), in lateral view, directed posteriorly, with two dentiform processes on ventral portion: an apical and a subapical one, pair of wing-shaped processes on dorsolateral portions of apex. Paraphyses ( Figure 2F View Figure 2 ) paired, symmetrical, extending below shaft of aedeagus; rami short, curved dorsally and approximately parallel.

Female genitalia

Abdominal sternite VII ( Figure 2G View Figure 2 ) longer than wide, gradually tapered; posterior margin with concavity with slight round prominence at middle. Valvulae II ( Figure 2H View Figure 2 ) with ventral margin approximately rectilinear, dorsal margin approximately parallel to ventral one; preapical prominence distinct; primary teeth inclined trapezoid on basal and median portions ( Figure 11H View Figure 11 ), becoming triangular towards apex ( Figure 11I View Figure 11 ); first ones with posterior flat area, which becomes gradually smaller towards apex, where it is absent ( Figure11J View Figure 11 ); denticles on all teeth and on apical portion; ventral dentate apical area greater than dorsal one ( Figure11J View Figure 11 ).

Comparative notes

Scopogonalia subolivacea has a colour pattern similar to those of S. paula Young ( Mejdalani 1995) and S. amazonensis sp. nov. It differs from these mainly because of the two conspicuous dentiform processes on the ventral portion of the aedeagus ( Figure 2F View Figure 2 ). Scopogonalia paula has a single process, the apical one, and S. amazonensis presents both processes but they are reduced and partly fused ( Figure 6E View Figure 6 ).
