(Fig. 4)

Type-locality: near Tingo María, Huánuco Region, Peru.

Length: 7.0– 7.2 mm.

Coloration: Body yellow dorsally, and light yellow ventrally (Figs. 4A–B). Pronotum and mesonotum with muscular markings slightly darker. Forewing translucent, yellow, without maculae or spots (Figs. 4A–B).

External morphology: Coronal suture not reaching midlength of crown; frontal region convex in lateral view (Fig. 4A). Clypellar suture arcuate. Clypellus tapering apically. Forewing with few extra crossveins on costal margin, arriving only from outer anteapical cell (Figs. 4A–B). Profemur intercalary row with 11 to 13 setae; row AV with 13 to 14 short, stout macrosetae. Protibia rows AD+PD with 1+4 macrosetae. Other characters as in the generic description.

Male genitalia: Pygofer with dorsal process short, bifurcate, curved posteroventrally (Fig. 4C). Subgenital plate apex acuminate, reaching beyond apex of pygofer in lateral view (Fig. 4D). Connective arms closely appressed in dorsal view (Fig. 4E). Style apophysis apex rounded, smooth, somewhat straight, not reaching midlength of subgenital plates in dorsal view, reaching beyond connective stem in dorsal view (Fig. 4E). Aedeagus with pair of basidorsal processes; each long and curved dorsally with apex curved laterally in ventral view; apical process flap-like; gonopore apical (Fig. 4F–G). Phragma membranous, with setae dorsally, closely ensheathing basidorsal process, extending apically as narrow lobe.

Female terminalia: Female unknown.

Etymology: The species epithet refers to the slender male genitalia relative to the other species of the genus. The word gracilis means slender in Latin.

Notes: Brincadorus gracilis sp. nov. can be distinguished by the slender subgenital plates (Fig. 4D), slender aedeagus shaft relative to Brincadorus quincemil sp. nov. (Fig. 4F), and apex of basidorsal processes membranous without any teeth (Fig. 4F–G).
