Saltadorus dietrichi sp. nov.

( 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 ).

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).

Type-material: holotype ♂, “ PERU: Huánuco, 8 km S Tingo María, Pte.Cuevas , 620m 9°21’27”S 75°59’32”W 24 Oct 2002, C.H.Dietrich, on wet sand, 02-37-1” ( MUSM) .
