Brincadorus cruceno

description: Brincadorus cruceno sp. nov.
(Figs. 2, 3)
Type-locality: Potrerillos del Guenda Nature Reserve, Santa Cruz Department, Bolivia.
Length: 5.3–5.6 mm (males)
Coloration: Body yellow dorsally, and light yellow ventrally (Figs. 2A–B). Crown, pronotum, and mesonotum with muscular markings slightly darker (Figs. 2A–B). Forewing translucent, yellow, without maculae or spots (Figs. 2A–B).
External morphology: Coronal suture reaching midlength of crown; frontal region slightly upturned in lateral view; crown texture with arching carinae coarse anteriorly and becoming faint posteriorly (3A–B); anterior margin with numerous transverse carinae (Figs. 2A–B, 3A–D). Clypellar suture arcuate. Clypellus tumid in lateral view; constricted at base and tapering toward apex. Forewing without extra crossveins on costal margin (Figs. 2A–B). Profemur intercalary row with 12 to 14 setae; row AV with 4 to 7 short, stout macrosetae. Protibia rows AD+PD with 1+4 or 1+5 macrosetae. Other characters as in the generic description.
Male genitalia: Pygofer with dorsal process, acute, curved posterodorsally (Fig. 3E–F). Subgenital plate apex acuminate, extending beyond apex of pygofer in lateral view (Figs. 2C–D). Connective arms somewhat parallel in dorsal view (Fig. 2E). Style apophysis apex rounded, smooth, somewhat straight, not reaching midlength of subgenital plates in dorsal view (Fig. 2E). Aedeagus shaft curved dorsally; without basidorsal processes; preapical spine dorsally; apical region curved downwards; gonopore preapical, opening ventrally (Fig. 2F–G). Phragma forming elongate lobes, membranous dorsally, with setae dorsally, lightly sclerotized ventrally (Fig. 2F). Segment X ventrally protuberant (Fig. 3F–G).
Female terminalia: Female unknown.
Etymology: The epithet of the new species refers to those who are born in the Santa Cruz department, Bolivia, the type-locality of the holotype. The epithet is a noun in apposition to the generic name.
Notes: Brincadorus cruceno sp. nov. is similar to B. laticeps, as they both share the subgenital plates acuminate apically, and the long, slender and curved aedeagus. However, the new species can be distinguished by the shorter subgenital plates (Fig. 2B), with apical region straighter and less projected beyond pygofer in lateral view, style apophysis slightly shorter in dorsal view (Fig. 2E), and aedeagus with a pre-apical dorsal spine and apical region curved downward (Figs. 2F–G). In addition to the material examined below, the species is known from the misidentified paratype of B. laticeps from Rurrenabaque, Bolivia.
