Camisão, Beatriz M., Zahniser, James N. & Takiya, Daniela M., 2024, On the Neotropical Brincadorus: redescription, new species, taxonomic key and description of a related new genus (Insecta: Hemiptera: Cicadellidae: Deltocephalinae), Zootaxa 5497 (4), pp. 537-558 : 549

Brincadorus quincemil sp. nov.

( Fig. 6 )

Type-locality: near Quincemil, Cusco Region, Peru.

Length: 7.4 mm.

Coloration: Body yellow dorsally, and light yellow ventrally ( Figs. 6A–B ). Pronotum and mesonotum with muscular markings slightly darker. Forewing translucent, yellow, without maculae or spots ( Figs. 6A–B ).

External morphology: Coronal suture not reaching midlength of crown; frontal region convex in lateral view ( Fig. 6A ). Clypellar suture arcuate. Clypellus tapering apically. Forewing without any extra crossvein on costal margin ( Fig. 6A ). Profemur intercalary row with 18 setae; row AV with 8 to 10 relatively long macrosetae. Protibia rows AD+PD with 1+4 macrosetae. Other characters as in the generic description.

Male genitalia: Pygofer with dorsal process short, sickle-like, curved posteroventrally ( Fig. 6C ). Subgenital plate apex bifurcate, not reaching apex of pygofer in lateral view ( Fig. 6D ). Connective arms divergent in dorsal view ( Fig. 6E ). Style apophysis apex truncate, smooth, somewhat straight, not reaching midlength of subgenital plates in dorsal view ( Fig. 6E ). Aedeagus with pair of basidorsal processes longer than shaft, tubular, with preapical dorsal tooth; apical process wide in lateral view, flap-like; gonopore subapical, on ventral side ( Fig. 6F–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, near Quincemil community in Peru. The epithet is in apposition to the generic name.

Notes: Brincadorus quincemil sp. nov. resembles B. limoncocha sp. nov. as they both share forewings without crossveins on costal margin, and aedeagus with bifurcate basidorsal process. However, the former can be distinguished from all other Brincadorus by its subgenital plates with apices bifurcate ( Fig. 6D ) and aedeagus basidorsal process with short rami ( Figs. 6F–G ).

Type-material: holotype ♂, “ PERU: Cusco, 27 rd km W | Quincemil , 1013m | 13°21’57”S 70°53’51”W | 23–26.VIII.2012 Malaise | RR Cavichioli, JA Rafael, APM | Santos & DM Takiya” ( MUSM). 1♂ paratype, same data as above, “ENT2406” ( DZRJ) .
