( Fig. 7 ) Type-locality: Yanayacu, Tungurahua Province , Ecuador . Length: 5.3 mm . Coloration: Body yellow dorsally, and light yellow ventrally ( Figs. 7A–B ). Crown, pronotum and mesonotum with muscular markings slightly darker ( Figs. 7A–B ). Forewing translucent, yellow, without maculae or spots ( Figs. 7A–B ). External morphology: Coronal suture not reaching midlength of crown; frontal region slightly upturned in lateral view; crown texture with arching carinae coarse anteriorly and becoming faint posteriorly; anterior margin with numerous transverse carinae ( Figs. 7A–B ). Clypellar suture arcuate. Clypellus tumid in lateral view; constricted at base and tapering toward apex. Forewing without extra crossveins on costal margin ( Figs. 7A–B ). Profemur intercalary row with 10 to 11 setae; row AV with 5–6 moderately long macrosetae. Protibia rows AD+PD with 1+3 relatively small macrosetae. Other characters as in the generic description. Male genitalia: Pygofer with dorsal process short, curved posteroventrally ( Fig. 7C ). Subgenital plate inner margin excavated; apex oblique, thorn-like, projecting caudally, extending beyond apex of pygofer in lateral view ( Figs. 7C–D ). Connective relatively long, sinuate in lateral view; arms nearly parallel, slightly separated medially, closely appressed anteriorly ( Fig. 7E–F ). Style apophysis apex acuminate, smooth, not reaching midlength of subgenital plates, not extending beyond connective stem ( Fig. 7E–F ). Aedeagus without processes; shaft short, slightly expanded at midlength, becoming narrower towards apex, apex directed posterodorsally in lateral view; gonopore apical, opening dorsally ( Figs. 7F–G ). Phragma forming pair of long membranous lobes, with setae, ensheathing aedeagus shaft. Female terminalia: Female unknown. Etymology: The epithet of the new species refers to the type-locality of the holotype , Yanayacu, Ecuador . The epithet is in apposition to the generic name. Notes: Brincadorus yanayacu sp. nov. resembles B. laticeps and B. cruceno sp. nov. , as they all lack basidorsal processes on the aedeagus. However, the new species can be distinguished by the relatively long connective, which is sinuate in lateral view, the thorn-like tips of subgenital plates, and short aedeagus, slightly expanded at midlength, and becoming narrower towards apex in lateral view ( Figs. 7E–G ).
