Mendozellus paralaredanus View in CoL sp. n.

( Figs 4–5 View FIGURE 4 View FIGURE 5 )

Length. Male: 2.3–2.5 mm; female: 2.4–2.7 mm.

Coloration and morphology. Ground color reddish brown marked with white; vertex, pronotum, mesonotum, scutellum, and inner margin of forewing with wide medial pale line. Vertex with faint marks. Pronotum with four white longitudinal stripes in addition to medial pale line ( Fig. 4 View FIGURE 4 A–D). Face light reddish brown, with paired white arcs and white longitudinal stripe on frontoclypeus ( Fig. 4 View FIGURE 4 F). Forewing with veins pale, inner margin of clavus with broad white band ( Fig. 4 View FIGURE 4 A–D). Mesosternum dark. Tibiae with dark marks ( Fig. 4 View FIGURE 4 E).

Head wider than pronotum, anterior margin distinctly angulate in dorsal view, vertex longer than distance between eyes ( Fig. 4 View FIGURE 4 A–D). Anteclypeus tapering to apex, extending beyond normal curve of genae. Lorum semicircular, slightly narrower than anteclypeus, well separated from lateral margin of face ( Fig. 4 View FIGURE 4 F). Pronotum nearly as long as vertex ( Fig. 4 View FIGURE 4 A–D). Forewing exposing apex of pygofer in female, with four short apical and three anteapical cells, middle anteapical cell with one crossvein, inner anteapical cell usually closed basally, appendix reduced ( Fig. 4 View FIGURE 4 A–E).

Male genitalia. Pygofer lightly sclerotized dorsally, pygofer lobe short, caudal margin bluntly angled, with numerous macrosetae in posterior region ( Fig. 5 View FIGURE 5 A–B). Subgenital plate subtriangular, lateral margin more or less straight, apex acute, with 4–5 macrosetae arising laterally ( Fig. 5 View FIGURE 5 C). Style preapical lobe nearly rectangular; apophysis stout, slightly laterally curved with imbricate microsculpture; basal arms very strongly divergent ( Fig. 5 View FIGURE 5 D). Aedeagus in lateral view stout and broadly upturned on distal third, with lateroventral tooth distally; gonopore subapical on ventral surface, very large ( Fig. 5 View FIGURE 5 E–F).

Female ovipositor. Sternite VII with posterior margin concave medially, with two posterolateral lobes attached on inner surface ( Fig. 4 View FIGURE 4 G). First and second valvulae as in M. asunctia Cheng.

Type material. Holotype ♂, Uruguay, Colonia, Ruta 21, km 194, San Pedro , 23-XII-1983, G.J. Wibmer, INHS . Paratypes: 9♂, 9♀, same data ; 1♂, 4♀, Uruguay, Colonia, Piedra de los Indios, ca. Ruta 21, km 184 1/2, 23- XII-2005, G.J. Wibmer, INHS .

Etymology. The specific epithet is based on the similarity of this species to M. laredanus Oman. Remarks. This species closely resembles M. laredanus Oman and M. albolectus DeLong & Cwikla , but is readily distinguishable by color, the shape of the style, and the apex of the aedeagal shaft.
