Mendozellus rakitovi View in CoL sp. n.

( Figs 6–7 View FIGURE 6 View FIGURE 7 )

Length. Male: 2.8 mm; female: 3.4 mm.

Coloration and morphology. Ground color pale ochraceous marked with black-brown; vertex, pronotum, mesonotum and scutellum with wide medial pale line. Vertex with black-brown marks. Pronotum with six blackbrown longitudinal stripes ( Fig. 6 View FIGURE 6 A–B, 6G). Face stramineous, with paired white arcs on frontoclypeus ( Fig. 6 View FIGURE 6 H). Forewing subhyaline with veins contrastingly pale, veins sometimes bordered with fuscous ( Fig. 6 View FIGURE 6 A–F). Mesosternum pale ochraceous. Tibiae with dark marks ( Fig. 6 View FIGURE 6 C–D).

Head wider than pronotum, anterior margin distinctly angulate in dorsal view, vertex slightly shorter than distance between eyes ( Fig. 6 View FIGURE 6 A–B). Anteclypeus tapering to apex, extending beyond normal curve of genae. Lorum semicircular, slightly narrower than anteclypeus, well separated from lateral margin of face ( Fig. 6 View FIGURE 6 H). Pronotum nearly as long as vertex ( Fig. 6 View FIGURE 6 A–B). Forewing exposing apex of pygofer, with four short apical and three anteapical cells, middle anteapical cell with one-three crossveins, inner anteapical cell closed basally sometimes with one crossveins, appendix reduced ( Fig. 6 View FIGURE 6 A–F).

Male genitalia. Pygofer lightly sclerotized dorsally, pygofer lobe long, caudal margin round, with numerous macrosetae in posterior region ( Fig. 7 View FIGURE 7 A–B). Subgenital plate subtriangular, lateral margin weakly incurved, apex acute, with 5–6 macrosetae arising laterally ( Fig. 7 View FIGURE 7 C). Style preapical lobe nearly rectangular; apophysis stout, slightly laterally curved ( Fig. 7 View FIGURE 7 C). Aedeagus simple, without processes, in lateral view upturned distally, thinnest at midlength; gonopore apical ( Fig. 7 View FIGURE 7 E–F).

Female ovipositor. Sternite VII with posterior margin concave medially, with two posterolateral lobes attached on inner surface ( Fig. 6 View FIGURE 6 I). First and second valvulae as in M. asunctia Cheng.

Type material. Holotype ♂, Peru: Junin, 42 km NE La Oroya , 4,000m, 11°24′18"S, 75°50′31"W, 17-X-2002, C.H. Dietrich & R. Rakitov, sweeping GoogleMaps , 02-15-2, USML. Paratypes: 1♂, 1♀, same data, INHS. Etymology. This species is named for Dr. Roman Rakitov of the Paleontological Institute, Moscow, who organized the collecting trip that yielded the type specimens.

Remarks. This species resembles M. paralaredanus sp. n., but is readily distinguishable by color and the shape of the aedeagus. Fig. 7 View FIGURE 7 D comes from a teneral specimen (male paratype) with genitalia only lightly sclerotized.
