Brincadorus gracilis sp. nov.

( 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 ).
