Zhang, Yalin, Zhang, Xinmin & Wei, Cong, 2010, Review of the genus Boundarus Li & Wang (Hemiptera: Cicadellidae: Evacanthinae) from China, with description of two new species, Zootaxa 2575, pp. 63-68 : 66-68

Boundarus nigronotus sp. nov.

( Figs 13–18 , 31–35 , 44–47 )

Measurements: ɗ: body length: 5.5–6.0; head width (incl. eyes): 1.3–1.5; head length: 0.8–0.9. Ψ: body length: 6.0–7.0; head width (incl. eyes): 1.5–1.6; head length: 0.7–0.9.

Disk of head black; pronotum and scutellum totally black; forewing generally black, with veins whitish yellow ( Figs 13–18 ).

Male pygofer without macrosetae; subgenital plate extended well beyond apex of pygofer, with more hairlike setae ( Figs 31, 35 ). Aedeagus with atrial processes foliate in lateral view; apical processes short, about one fourth length of shaft in lateral view, broadened basally in posterior view ( Figs 32, 33 ).

Etymology: The species name refers to the black pronotum and scutellum.

Material examined: HOLOTYPE: ɗ ( NWAFU), China: Henan Prov., Luanchuan County, Longyuwan, 2000m, 13-July-1996, coll. Cai Wangzhi; PARATYPES: 1ɗ ( IZAS), China: Sichuan Prov., Mt. Emeishan, 1000–1600m, 26-June-1955, coll. Wu Le; 2ɗ ɗ, 20Ψ Ψ ( IZAS), China: Sichuan Prov., Mt. Emeishan, 1000– 1600m, 26-June-1955, coll.

Zhang Wenzhu; 1ɗ, 5Ψ Ψ ( NWAFU), China: Shaanxi Prov., Ningshan County, Houditang, 17-July-1984, coll. Zhang Yalin; 4Ψ Ψ ( NWAFU), China: Jilin Prov., Hongtushan, 2-August-1983, coll. Wu Zhengliang & Hua Baozhen; 1Ψ ( NWAFU), China: Guizhou Prov., Fanjingshan, 21-July-1986, coll. Li Zizhong; 1ɗ ( NWAFU), China: Hubei Prov., Wufeng, 2253m, 11-July- 2006, coll. Lu Lin.

Remarks: This species is distinctly different from the other two species of the genus by its body shape and coloration, in addition to the much longer subgenital plates, and the robust apical processes of the aedeagus in ventral view. It is similar to some known species of the genus Evacanthus Le Peletier and Serville externally, particularly in the color pattern of the forewings, but it is closer to the other species of Boundarus in having the same distribution of carinae on the head, similar male genitalia and other characteristics as listed in table 1. Therefore, it is tentatively placed in the genus Boundarus .
