description: Subrasaca rachelae Silva, Cavichioli et Mejdalani, sp. nov.
(Figs 38–46)
Length. Male holotype, 5.3 mm; male paratypes, 5.1 mm (n = 2); female paratypes, 5.4–5.5 mm (n = 2).
Holotype description. Head and thorax. Structural features of head and thorax much as described above for S. diminuta sp. nov., except for muscle impressions of frons not distinct and mesonotum with scutellum not transversely striate behind transverse sulcus.
Color. Anterior dorsum yellowish-brown to brown. Crown (Fig. 38) with large, conspicuous symmetrical orange mark delimiting pair of yellowish-brown to brown anterolateral areas and posterior M-shaped area. Pronotum (Fig. 38) with pair of large orange maculae extending from posterolateral margins and almost reaching median line, area posterad of maculae dark brown. Mesonotum (Fig. 38) with scutum dark brown, delimiting pair of yellowish-brown spots. Forewings (Fig. 38) mostly dark brown with unpigmented areas along costal margin and along inner claval margin; with three conspicuous longitudinal orange stripes (one from base to apex of clavus; one on corium, near costal margin, extending from basal portion to level of clavus apex; and one on corium from apex of clavus to base of second apical cell); posterior portion of forewing with orange spot near costal margin. Face, lateral and ventral portions of thorax, and legs yellow.
Male genitalia. Pygofer (Fig. 39), in lateral view, not strongly produced posteriorly; posterior margin narrowly round; without processes; macrosetae distributed mostly on distal third of disk and more anteriorly on ventral portion. Subgenital plates (Fig. 40), in ventral view, subtriangular, basal third expanded laterally, then tapering gradually toward apex; connected to each other basally by small membranous triangular area; in lateral view, not extending as far posteriorly as pygofer apex; with few uniseriate macrosetae. Connective (Fig. 41), in dorsal view, short, Y-shaped but with arms poorly differentiated; stalk broad. Style (Fig. 41), in dorsal view, extending posteriorly farther than apex of connective; preapical lobe distinct, with few setae; apical portion directed outward, apex narrow, truncate. Aedeagus (Fig. 42) short; in lateral view, with dorsal lobe directed posteriorly, bearing pair of sclerotized spiniform dorsal processes located preapically, ventral margin of shaft distinctly convex; gonoduct distinct, sclerotized. Paraphyses (Fig. 43) symmetrical with two rami; base of each ramus, in dorsal view, with strong dentiform projection directed posteromedially; apex of rami, in lateral view, distinctly expanded.
Female genitalia. Abdominal sternite VII (Figs 44, 45), in ventral view, with posterior margin weakly trilobed. Internal sternite VIII (Fig. 46), in dorsal view, with pair of small, linear transverse sclerites located above bases of first valvulae. Pygofer, first valvifers, ovipositor valvulae, and gonoplacs much as described above for S. diminuta sp. nov. Second valvulae with about 20 teeth.
Etymology. The new species is described in honor of Dr. Rachel A. Carvalho (Museu Nacional, Universidade Federal do Rio de Janeiro) in recognition of her contribution to our knowledge of the Neotropical Cicadellinae. She was also one of the collectors of the holotype and other specimens of the type series.
