( Fig. 10 ) Type-locality: Puente Cuevas, ca. Tingo Maria, Huánuco Region , Peru . Length: 4.0 mm Coloration: General color light brown. Crown with a pair of round dark brown maculae near posterior margin; area around ocelli dark brown ( Fig. 10A ). Frontoclypeus brown. Clypellus, lorae, and legs whitish. Pronotum with muscular markings on anterior half dark brown ( Fig. 10A ). Mesonotum with pair of large subtriangular lateral maculae and small median macula on anterior margin, dark brown ( Fig. 10A ). FIGURE 10. Saltadorus dietrichi sp. nov. , male holotype. A, Dorsal habitus; B, Lateral habitus; C, Pygofer, valve, subgenital plate, connective, styles, aedeagus and anal tube, lateral view; D, Pygofer, valve, subgenital plate, connective, styles, aedeagus and anal tube, ventral view; E, Connective, styles, and aedeagus, dorsal view; F, Connective, styles, and aedeagus, lateral view. External morphology: Head with median length slightly longer than next to eye; coronal suture reaching beyond midlength of crown ( Fig. 10A ). Clypellar suture arcuate. Clypellus widening medially and tapering apically, tumid in lateral view. Profemur with intercalary row with 10–12 setae; row AV with 3 moderately long, stout setae and ~5 relatively long, fine setae. Other characters as in the generic description. Male genitalia: Pygofer posterior margin rounded; with setae on posterodorsal margin; pair of inner lateral processes arising sub-basally on dorsal region, directed posteriorly, thick at base, becoming narrowed on posterior two-thirds in lateral view, apex slightly expanded, apex extending posteriorly beyond apex of pygofer in lateral view ( Fig. 10C–D ). Subgenital plate with several setae restricted to extreme apex; outer margin convex near base in ventral view, becoming approximately straight toward the apex; inner margin strongly concave in ventral view, apical half becoming narrower; apex turned upward and inward, forming sharp tooth ( Fig. 10D ). Aedeagus robust; broader at base, narrowing toward apex; beyond atrium, dorsal margin forming a saddle-like shape, slightly concave, then angulately curved ventrad before apical part; apical part with pair of triangular teeth on dorsal margin; apex with dorsal expansion; sclerotized gonoduct protruding from atrium, recurved back inside and again out of atrium; gonopore apical, with margins more sclerotized and thickened ( Fig. 10E–F ). Other characters as in generic description. Female terminalia: Female unknown. Etymology: The new species is named after Dr. Christopher Dietrich ( Illinois Natural History Survey, USA ), a leafhopper specialist, who collected and kindly photographed the holotype . Notes: Saltadorus dietrichi is very similar to S. blahniki , but it can be identified by the shorter male pygofer, the saddle-shaped dorsal margin of the aedeagus, and the presence of subapical dorsal teeth on the aedeagus ( Figs. 10C–F ). The holotype of S. dietrichi was included in the phylogenetic analyses by Cao et al. (2022) as an undescribed species of Brincadorus (see Discussion).
