The planthopper genus
The morphological terminology and measurements used in this study follow
The following abbreviations are used in the text:
Genus diagnostic characters: general color green or yellowish green (in death); vertex with median carina distinct and complete, lateral margins sub-parallel at base, slightly sinuate in front of eyes, then gradually narrowing to arrowhead at apex; pronotum with distinct median carina and two obscure lateral discal carinae, elevated only anteriorly; fore femur with one minute, short and blunt spine near apex; aedeagus with a pair of processes apically and phallobase with pairs of membranous lobes apically.
Southern China (Guizhou, Hubei, Sichuan, Taiwan, Xizang).
1 | Vertex narrow and long, ratio of length to width is greater than 2.4 |
|
– | Vertex broad and short, ratio of length to width is not greater than 2.4 |

2 | Pygofer posterior margin with distinct, posteriorly directed process near apex in lateral view; phallobase with 2 pairs of membranous lobes at apex |
|
– | Pygofer posterior margin with not distinct, posteriorly directed process near apex in lateral view (Fig. |

3 | Aedeagus with 1 pair of equally long processes apically, processes with apex acute, sclerotized and pigmented. Phallobase sclerotized and pigmented at base, with 3 pairs of membranous lobes at apex |

♂,
This species is similar to
General color green; carinae on cephalic process, frons, pronotum and mesonotum, and parts of veins on forewings, dark green; rostrum with extreme apex blackish; hind tibia with lateral and apex black-tipped spines .
Holotype ♂, China, Guizhou, Kuankuoshui, Qing gang tang hui long county. 17.VIII. 2010, Lihu. Paratypes, 1♂2♀♀, same to Holotype; 9♂♂5♀♀, China, Guizhou, Fanjing mountain, 27.VII. 2001, Lizizhong.
This new species is named for the holotype occurrence in “Kuankuoshui”, Guizhou province in southwestern China.
♂,
This species can be distinguished from other species from aedeagus and phallobase. The aedeagus with pair of unequal long processes apically; phallobase with numerous membranous lobes at apex.
General color and external characters as the
Holotype ♂, China, Guizhou, Institute of Entomology. XII. 2008, Light trap, Zhangyubo. Paratypes, 6♀♀, data same as holotype.
This new species is named for the Greek word “
The discovery of two new species broadens our knowledge of the morphology and biogeography of the genus. The two new species both occur in Guizhou, China. This may be due to the climate of Guizhou, warm and humid, subtropical humid monsoon, and minimal temperature changes. All described species are distributed in the Palearctic and Oriental regions.
