Yang, Mao-Fa, Meng, Ze-Hong & Yu, Xiao-Fei, 2015, Three new species of Anatkina Young (Hemiptera: Cicadellidae: Cicadellini) from China, with a key and checklist of known Chinese species of the genus, Zootaxa 3919 (3), pp. 479-492 : 482

Anatkina alata Yang, Meng & Yu, sp. nov.

( Figs 10–18 )

Type material. Holotype, ♂, Baihualing, Mt. Gaoligong, Yunnan, 28. May.–3. June. 2009, collected by Zaihua Yang and Bin Li. Paratype, 1♂, same data as holotype.

Length: ♂ 9.4–9.5 mm.

Coloration ( Figs 10–12 ). Body surface covered with thin blue-white wax powders. Head, thorax and forewing black in dorsal view. Ocelli, inner margin of eyes, antennae, posterior margin of pronotum and apical angle of scutellum yellowish-brown. Forewing with three longitudinal red stripes, one extending almost from base to apex of clavus, two in corium converging at base, one of which near and parallel to claval suture, extending slightly beyond claval suture, the other parallel to anterior half of forewing costal margin. Face yellowish-white, frontoclypeus with broad longitudinal black band on each side, anteclypeus with triangular black spot on basal portion. Thoracic sternum black with yellowish-brown stripes; legs yellowish-white; tibiae, tarsi and pretarsi of prothoracic legs black; meso- and metapretarsi blackish-brown. Abdomen black in ventral view; sternites with posterior margins pale; base of subgenital plate and posteroventral portion of pygofer with pale macula.

External features. Head moderately produced, anterior margin broadly round; median length of crown slightly less than 2/3 of interocular width; crown concave between ocelli, with fovea between ocelli and eye; ocelli located slightly behind imaginary line between anterior eye angles; lateral frontal sutures extending onto crown and attaining ocelli; frontoclypeus slightly convex medially, muscle impressions distinct; transclypeal suture complete. Pronotum width equal to or slightly less than transocular width of head; anterior margin rounded; posterior margin shallowly concave medially; scutellum slightly convex behind transverse depression; forewing with apical membrane indistinct, base of second apical cell almost aligned with base of third; hindleg with femoral setal formula 2:1:1.

Male genitalia. Pygofer ( Fig. 13 ) broad and short, in lateral view with posterior margin roundly convex; surface with macrosetae on posterior margin; pygofer process extending posteriorly farther than apical margin, apical portion bended posteroventrally and with acute apex, dorsal margin with minute denticles subapically. Subgenital plates ( Fig. 14 ) slender, produced posteriorly farther than pygofer, progressively narrower toward apical portion, apical portion slightly broader and dorsally curved; surface with longitudinal uniseriate macrosetae on median portion and few short microsetae on inner posterolateral margin. Aedeagus ( Figs 15, 16 ) broad and long, extending posteriorly beyond apex of paraphyses, curved ventrally at median portion, with ventral dental process apically, and pair of wing-like processes subapically. Paraphyses ( Figs 15, 16 ) spoon-like, with acute apex. Connective ( Fig. 17 ) V-shaped. Style ( Fig. 18 ) short, apical portion curved and with acute apex.

Etymology. The specific epithet, alata, is of Latin derivation and refers to the pair of wing-like subapical processes of the aedeagus.

Remarks. This new species is similar to A. bistriata Yang & Li, 2001 , but can be readily distinguished by the crown and pronotum without distinctly pale white spots or stripes, forewing with three longitudinal red stripes, anteclypeus yellowish-white with a triangular black spot on basal portion, male pygofer process curved apically, subgenital plates with apical portion broader, aedeagus with wing-like process subapically, paraphyses spoon-like, and connective V-shaped.
