Duan, Yani & Zhang, Yalin, 2010, Review of Chinese species of genus Xenovarta Viraktamath (Hemiptera: Cicadellidae: Deltocephalinae: Scaphytopiini) with description of a new species, Zootaxa 2490, pp. 40-46 : 43-45

Xenovarta longicornis sp. n.

( Fig. 1 ; plate I: C–G)

Dark bluish green; margins of vertex anterior to eyes bright red; median area of frontoclypeus, basal areas of clypellus and lora ochraceous; pronotum with two red stripes on either side of median line; scutellum laterally and basally brownish ochraceous; forewing with red stripes as in plate I: G, apical area brownish hyaline.

PLATE I. A: Xenovarta ankusha Viraktamath, 2004, dorsal habitus; B: Xenovarta acuta Viraktamath, 2004, dorsal habitus; C– G: Xenovarta longicornis sp. n., C: dorsal habitus; D: lateral habitus; E: face; F: apex of female abdomen; G: forewing.

Vertex acutely triangularly produced in front of eyes, about 2.5x as long as interocular width, 1.7x as long as pronotum, lateral margins sharp, carinate, upturned.

Male genitalia. Pygofer elongate, dorsal margin strongly inclined ventrally, with sclerotised submarginal band from base of anal tube extending caudally and terminating in short triangular process at ventroposterior margin; without macrosetae. Valve fused to subgenital plates the latter with uniseriate row of macrosetae. Style apophysis footlike, distally rugulose. Connective narrowly Y-shaped, with arms about as long as stem. Aedeagal shaft asymmetrical, strongly arched in lateral aspect, slightly laterally compressed with welldeveloped dorsal process near midlength, gonopore apical.

Female genitalia. Female seventh sternum straight medially on posterior margin.

Measurements. Male: 5.6–5.9mm, Female: 6.3–6.5mm.

Material examined. Type. Holotype: ɗ, China, Hainan Prov., Diaolue Mountain, 02.vi.2007, coll. Duan Yani ( NWAFU). Paratypes: China, Hainan Prov.: 1ɗ, 1Ψ, data same as holotype; 1Ψ, Jianfengling, 12.xi.1982, coll. Chen Xiaomi (SYU); 1Ψ, Jianfengling, 29.viii.2002, coll. Wang Zongqing ( NWAFU); 1ɗ, Limu Mountain, altitude: 665m, 13.viii.2009, coll. Gaoxia ( NWAFU).

Remarks. This species is similar to Xenovarta cylindrica Viraktamath , but can be distinguished by the foot-shaped apophysis of the style and by the aedeagus having a well-developed dorsal process near midlength.

Etymology. The name of this species is based on the well-developed dorsal process of the aedeagus.
