D., Cavichioli, Rodney R. & Mejdalani, Gabriel, 2021, Two new species of the sharpshooter genus Paratubana (Hemiptera: Cicadellidae Cicadellini) from alpine fields of Rio de Janeiro state, southeastern Brazil, Zootaxa 5005 (3), pp. 339-348 : 342-343

Paratubana takiyae sp. nov.

( Figs 8–24 , 28–30 )

Total length. Male holotype 8.2 mm, female paratypes 8.0–8.5 mm (n = 2).

Head and thorax ( Figs 28–30 ) much as described above for P. auromarginata sp. nov.

Coloration ( Figs 28–30 ). Crown and pronotum black with yellow markings distributed as follows: crown with pair of large areas between ocellus and eye, extending over antennal ledge and to posterior coronal margin, posterior portion with median bilobate spot extending to interocellar line; apex with spot extended from face; pronotum with pair of large spots connected to lateroposterior margins and continuous with line along lateral and posterior margins of disk. Eyes dark brown. Mesonotum black with yellow apex. Ground color of forewing light yellowish-brown, with broad longitudinal yellow stripe along costal margin, extending from base to R 1, evanescent behind this vein; veins mostly dark brown to black. Face black; frons with elongate median yellow spot, extending to anterior margin of crown; gena with yellow stripe along frontogenal suture; lorum mostly yellow; labrum yellowish-brown. Legs with coxa, trochanter, and large area of femur dark brown to black; remainder mostly yellow with brown areas; tarsal claws dark brown.

Male terminalia ( Fig. 8 ) with pygofer ( Fig. 9 ), in lateral view, strongly produced posteriorly; posterior margin rounded; without processes; surface with macrosetae distributed mostly on posterior 2/3, except dorsally. Valve ( Fig. 10 ), in ventral view, subrectangular, median portion constricted, followed by large membranous area. Subgenital plate ( Figs 9, 10 ), in ventral view, abruptly narrowed on basal 1/3; not extending posteriorly as far as pygofer apex; surface with numerous macro- and microsetae distributed near outer margin. Connective ( Fig. 11 ), in dorsal view, Y-shaped; stalk distinctly longer than arms, gradually narrowed towards apex, with distinct dorsal keel. Style ( Fig. 11 ), in dorsal view, not extending as far posteriorly as apex of connective; outer margin with well-developed lobe near mid-length; portion beyond lobe strongly curved and bearing setae; apex narrowed and obtuse. Paraphyses ( Figs 12, 13 ) slightly asymmetrical, well-developed; rami, in dorsal view, elongate, narrowed apically, with pair of strong spiniform processes on basal half, directed dorsally and crossing each other; in lateral view, paraphyses pincer-like; base of ramus robust. Aedeagus ( Fig. 14 ) symmetrical; shaft, in lateral view, claviform, median portion broad, not distinctly constricted, apical portion expanded, rounded; gonoduct (ductus seminis) distinct, well sclerotized, slightly curved ventrally; gonopore located apically.

Description of the female paratypes. External morphology and coloration similar to those of male holotype.

Female terminalia. Sternite VII ( Fig. 15 ), in ventral view, subrectangular; laterally expanded on basal half; apex bilobate with V-shaped median emargination; surface with median keel. “Internal” sternite VIII ( Fig. 16 ), in dorsal view, with large median sclerotized area. Pygofer ( Fig. 17 ), in lateral view, slightly produced posteriorly; posterior margin slightly angulate; macrosetae distributed mostly on posterior half, but some located more anteriorly. Valvifer I ( Fig. 18 ), in lateral view, subrectangular. Valvula I ( Figs 18–20 ), in lateral view, slightly expanded basally; blade slightly curved dorsally; apex acute; dorsal sculptured area extending from basal portion of blade to apex, formed mostly by scale-like processes arranged in oblique lines (strigate); ventral sculptured area restricted to apical portion of blade, formed mostly by scale-like processes; ventral interlocking device distinct on basal half of blade. Valvula II ( Figs 21–23 ), in lateral view, expanded beyond basal curvature; preapical prominence small but distinct; apex obtuse; dorsal margin with about 18 continuous low teeth; denticles distributed on teeth and on dorsal and ventral portions of blade; dorsal denticulate apical portion longer than ventral portion; blade with ducts extending to teeth and to apex. Gonoplac ( Fig. 24 ) of the usual Cicadellinae type: in lateral view, with basal half narrow and apical half distinctly expanded; apex obtuse; surface with few small setae on apex and along ventral margin.

Material examined. Atlantic Forest, southeastern Brazil, state of Rio de Janeiro ( RJ). Male holotype: “ BR / RJ—Teresópolis, P. [Parque] N. [Nacional da] Serra \ dos Órgãos, Trilha p/ Pedra do \ Sino (Parnaso 7) \ 27-28/ VII/2015 \ DM Takiya & APM Santos cols.” ( DZRJ). Paratypes: two females, same data as the holotype ( DZRJ, MNRJ) .

Etymology. The new species is named in honor of our colleague and dear friend Dr. Daniela Maeda Takiya (Departamento de Zoologia, Instituto de Biologia, Universidade Federal do Rio de Janeiro) in recognition of her outstanding contribution to the study of Neotropical Cicadellidae and other insect groups. She was one of the collectors of the type series.
