Brincadorus limoncocha sp. nov.

( Fig. 5 )

Type-locality: Limoncocha, Sucumbíos Prov., Ecuador.

Length: 6.3 mm.

Coloration: Body yellow dorsally, crown with diffuse brown band submarginally and with greenish coloration posteriorly; mesonotum with greenish coloration posteriorly at apex; light yellow ventrally ( Figs. 5A–B ). Pronotum and mesonotum with muscular markings slightly darker yellow. Forewing translucent, dark yellow, without maculae or spots, costal margin dark brown from base to 2/3 length of forewing ( Figs. 5A–B ).

External morphology: Coronal suture not reaching midlength of crown; frontal region convex in lateral view ( Fig. 5A ). Clypellar suture arcuate. Clypellus slightly constricted near base, tapering apically. Forewing without extra crossveins on costal margin ( Figs. 5A–B ). Profemur intercalary row with ~15 fine setae; row AV with 9 to 10 relatively long setae. Protibia rows AD+PD with 1+5 macrosetae. Other characters as in the generic description.

Male genitalia: Pygofer with dorsal process as in generic description ( Fig. 5C ). Subgenital plate apex acuminate, reaching beyond apex of pygofer in lateral view ( Fig. 5D ). Connective arms somewhat parallel in dorsal view ( Fig. 5E ). Style apophysis apex rounded, smooth, bluntly triangular, not reaching midlength of subgenital plates or apex of connective in dorsal view ( Fig. 5E ). Aedeagus with pair of basidorsal processes; long, arching mediodorsally, apex bifurcate: dorsal ramus thicker and curved ventrally, ventral ramus thinner and curved anteroventrally; without apical process; gonopore large, subapical on ventral side ( Fig. 5F–G ). Phragma membranous, with setae dorsally, closely ensheathing basidorsal process, extending apically as narrow lobe.

Female terminalia: Female unknown.

Etymology: The new species is named after the type-locality, at Limoncocha, Ecuador. The epithet is a noun in apposition to the generic name.

Notes: Brincadorus limoncocha sp. nov. is similar to Brincadorus gracilis sp. nov., as they share the apex of the subgenital plates acuminate, styles not reaching apex of connective, and overall shape of connective. However, Brincadorus limoncocha sp. nov. can be distinguished by its more robust subgenital plates ( Fig. 5D ), more robust aedeagus shaft ( Fig. 5F ), and apex of basidorsal processes bifurcate ( Fig. 5F–G ). The new species is also similar to Brincadorus quincemil sp. nov., as they share forewings without crossveins on costal margin, more robust subgenital plates, and apex of basidorsal process on aedeagus bifurcate. However, B. limoncocha sp. nov. can be distinguished from the latter by the more triangular valve, apex of subgenital plates not bifurcate, and overall shape of aedeagus.
