03BCCD135F04E436FF5CFC55EA499093.taxon	discussion	Remarks. Pruthi described this species from India based on two males and two females from India. Identification of our Chinese materal is made from a comparison of Pruthi’s figure of the male genitalia, in particular the shape of the aedeagal apex in lateral view. Li’s (1986) record of G. vexillum from China, may be this species. His figure (habitus only), is very similar to G. minorcephala. Zahniser (2008) provided good photographs of this species, including the male and female genitalia.	en	Duan, Yani, Zhang, Yalin (2012): A taxonomic review of the grassland leafhopper genera Gurawa Distant and Chiasmus Mulsant & Rey (Hemiptera: Cicadellidae: Deltocephalinae: Chiasmini) from China with description of a new species.
