Viraktamath, C. A., 2004, A revision of the Varta­Stymphalus generic complex of the leafhopper tribe Scaphytopiini (Hemiptera: Cicadellidae) from the Old World, Zootaxa 713, pp. 1-47 : 26

Xenovarta ankusha sp. nov.

Figs 48 , 154–162 .

Dark bluish green, margins of vertex anterior to eyes bright red, without black spots, lateral area of vertex mesad of eyes paler. Face bluish green except ochraceous median area of fronto­clypeus, basal areas of clypellus and lora. Pronotum bluish green except anterior paler border, a faint median pair and brighter lateral pair of longitudinal stripes red. Scutellum medially and apically green, rest brownish ochraceous. Front wing bluish green, apical area transparent, pale brown, red stripes as in Fig. 48 .

Head acutely triangularly produced in front of eyes, lateral margins sharp, upturned, 2.6 times as long as inter­ocular width, 1.8 times as long as pronotum.

Male genitalia: Pygophore caudally triangularly produced, with a number of macrosetae on caudo­dorsal area. Segment X broad, not exceeding pygophore. Valve and subgenital plates fused to form a median plate with a median slit extending almost 0.5 length of plate, with marginal row of macrosetae and a pair of caudal sclerotized lobes. Style with equally developed antero­lateral and antero­mesal angles, preapical lobe well­developed, apophysis long, with strong transverse rugulae, of uniform width and distally rounded. Connective Y­shaped, with stem short, arms long, in contact with each other anteriorly. Aedeagus with well­developed dorsal apodeme, shaft spatulate, twisted in distal half, terminated by two asymmetrically curved fingerlike processes, making it asymmetrical, gonopore subapical, arising on right hand side.

Measurements: Male 6.7 mm long, 1.2 mm wide across hind margin of head, 1.4 mm wide across hind margin of pronotum.

Material examined: CHINA: holotype ɗ, Guangdong: Fengkai: Heishiding, 8.viii.1986, H. Xiang, SunYet­sen University, Guangzhou: China ( NWAU).

Remarks: X. ankusha differs from other species of Xenovarta in having entire, conically produced pygophore and spatulate, medially twisted aedeagal shaft. It is not closely related to any of the included species in the genus though it shares the characters of the male pygophore with X. compressa .
