(Figs 1–21)

Type-locality: S„o José dos Pinhais, State of Paraná, South Brazil.

Measurements (mm). Holotype (male)—4.5. Paratypes — 10 males (4.1–4.7) and 36 females (4.9–5.6).

Color. Dorsum (Figs 1, 2, 4, 5) with background black in males and brownish in females, with ivory to yellowish bands and dots as follows: crown with anterior margin yellowish, posterior margin with small yellowish bands; pronotum with transverse irregular band from middle of the disk to the posterior margin; mesonotum with small bands; forewing with three transverse and fragmented bands, one basal, one median and other in the apical third, with several small scattered spots; apex with membrane smoky. Head (Figs 3, 6) with frons yellowish with muscle impressions black (males) or brown (females) and with some black or dark brown maculae medially; gena black with rounded yellow spot medially and with a very narrow yellow outer border; clypeus black with two yellow spots basally. Legs (Figs 2, 5) dark brown with yellow maculae.

Male genitalia. Pygofer (Fig. 7), in lateral view, short; posterior margin slightly angulated on dorsal third, macrosetae distributed on posterior two-thirds.Valve (Fig. 8), in ventral view, slender and transverse, subrectangular. Subgenital plate (Fig. 9), in ventral view, triangular, narrowing towards apex; outer margins with uniseriate row of macrosetae and long filiform setae at base; in lateral view (Fig. 7), plates almost extending as far as pygofer apex posteriorly. Style (Fig. 9), in dorsal view, short, attaining basal third of subgenital plate, with conspicuous preapical lobe and apex truncate, foot-like. Connective (Figs 9, 10), in dorsal view, short, Y-shaped, arms broad, stem narrow with well developed keel medially, surpassing arms anterad. Aedeagus (Fig. 12, 13) symmetrical, in lateral view, apodeme narrow, as long as shaft length; aedeagal shaft directed posteriorly, slightly curved dorsally, with pair of flanges laterally, arising near apodeme base and extending dorsally to apex, serrated apically; pair of apical acute processes directed anteriorly from which pair of lateroventral flanges extends anterad; gonopore subapical. Paraphyses (Figs 10, 11) symmetric, in lateral view, with base sclerotized and with two pairs of rami: basal one short and narrow, apical one wide and fused basally, abruptly tapered towards apex, with apex foot-like and directed inwards.

Female terminalia. Sternite VII (Fig. 14) with posterior margin produced and slightly truncated. Pygofer (Figs 14, 15), in lateral view, produced posteriorly, subtriangular and angled apically; macrosetae located mostly on posterior half and extending anteriorly along ventral margin. Internal sternite VIII membranous. First valvifer (Fig. 16) ellipsoidal, more expanded dorsally and with acute apex. First ovipositor valvula (Fig. 16, 17) well produced, slightly enlarged basally, blade slightly expanded towards apex, the latter acute; ventral interlocking device extending to half length of blade; dorsal sculptured area obliquely striate with very small scale-like projections, starting at basal third and extending to apex. Second valvula (Fig. 18–20) long, expanded beyond basal curvature, with dorsal and ventral margins subparallel, apex truncated obliquely, acute on the dorsal portion and with a distinct preapical prominence; dorsal margin with eleven long and very narrow, serrated teeth. Gonoplac (Fig. 21) 5.5x longer than high; dorsoapical margin long, with half length of gonoplac, straight, almost parallel to ventral margin; ventral margin slightly rounded, distal portion and apex with dentiform cuticular projections; apex subacute.

Etymology. We are pleased to name species for our friend and colleague, Sofia’s mother, Prof. Dr. Daniela Maeda Takiya, who has contributed to our knowledge of the Neotropical Cicadellidae.
