Paratubana auromarginata sp. nov.

( Figs 1–7 , 25–27 )

Total length. Male holotype 8.6 mm, male paratypes 8.5–8.7 mm (n = 4).

Head ( Figs 25–27 ), in dorsal view, slightly produced anteriorly; median length of crown approximately 1/2 interocular width and 3/10 transocular width; anterior margin broadly rounded; ocelli located approximately on imaginary line between anterior eye angles, each slightly closer to median line of crown than to adjacent anterior eye angle; crown with shallow transverse concavity across ocelli. Face with frons slightly flattened medially; muscle impressions distinct; epistomal suture obscure medially; clypeus with profile continuing contour of frons but with lower portion more nearly horizontal. Thorax ( Figs 25, 26 ), in dorsal view, with pronotal width less than transocular width of head; lateral margins slightly convergent anteriorly; posterior margin slightly concave; dorsolateral carina not distinct near posterior eye margin; posterior 2/3 of disk striate. Forewing mostly coriaceous, without sculpturing, membrane restricted to apical cells; veins elevated and distinct; with three anteapical cells, median and inner ones open basally (inner cell closed basally in some paratypes). Hind wing with vein R 2+3 incomplete. Hind leg with femoral setal formula 2:1:1. Other features of head and thorax as in the generic descriptions of Paratubana and Amblyscartidia ( Young 1977, p. 239 and 226, respectively).

Coloration ( Figs 25–27 ). Crown and pronotum black with yellow markings distributed as follows: crown with pair of curved stripes over antennal ledges and extending to ocelli; pair of adjacent spots located medially on posterior margin (may be absent or inconspicuous in paratypes); pair of lateral stripes behind eyes; pronotum with pair of small spots on median third (these spots may be larger in paratypes), lateral margins with elongate marking (may extend irregularly along posterior margin in paratypes). Eyes dark brown. Mesonotum black. Ground color of forewing yellowish-brown, with broad longitudinal yellow stripe along costal margin, extending from base to R 1, evanescent behind this vein; veins mostly dark brown to black. Face black; frons with median yellow macula on superior portion; gena with yellow stripe along frontogenal suture; labrum yellowish-brown. Legs with coxa, trochanter, and large area of femur dark brown to black; remainder mostly yellow with brown areas; tarsal claws dark brown.

Male terminalia ( Fig. 1 ) with pygofer ( Fig. 2 ), in lateral view, strongly produced posteriorly; posterior margin broadly rounded; without processes; surface with macrosetae distributed mostly on posterior 2/3, except dorsally; basiventral area with concentration of microsetae. Valve ( Figs 2, 3 ), in ventral view, subrectangular, median portion constricted, followed by membranous area. Subgenital plate ( Figs 2, 3 ), in ventral view, triangular; distinctly narrowed on basal 1/2; not fused to its counterpart; in lateral view, not extending as far posteriorly as pygofer apex; surface with numerous macro- and microsetae distributed mostly near outer margin. Connective ( Fig. 4 ), in dorsal view, Y-shaped; stalk distinctly longer than arms, gradually narrowed towards apex, with distinct dorsal keel. Style ( Fig. 4 ), in dorsal view, not extending as far posteriorly as apex of connective; outer margin with lobe near midlength; portion beyond lobe curved outwards and bearing setae; apex narrowed and blunt. Paraphyses ( Figs 5, 6 ) slightly asymmetrical, well-developed; rami, in dorsal view, very elongate, each one with strong, inner spiniform process on basal half and with apex bifurcate, forming outer subquadrate projection and inner spiniform process. Aedeagus ( Fig. 7 ) symmetrical; shaft, in lateral view, claviform, median portion constricted, apical portion with dorsal lobe, rounded; gonoduct (ductus seminis) distinct, curved ventrally; gonopore located ventroapically.

Female unknown.

Material examined. Atlantic Forest, southeastern Brazil, state of Rio de Janeiro ( RJ). Male holotype: “ BR / RJ—Nova Friburgo, \ Pico da Caledônia \ 22/VI/2019 \ Eq. [Equipe] Hemipterologia col. \ Coleta ativa” ( MNRJ). Paratypes: five males, same data as the holotype (two in DZRJ, two in MNRJ, and one in DZUP) .

Etymology. The new species name, auromarginata , refers to the broad longitudinal yellow stripe located along the forewing costal margin ( Fig. 26 ).
