title: New species and records of Asymmetrasca (Hemiptera: Cicadellidae: Typhlocybinae: Empoascini) from China and name changes in Empoasca (Matsumurasca).
abstract: Six new species of Asymmetrasca Dlabola are described from China: A. dahaituoensis, A. helica, A. hypercurvata, A. liaoensis, A. reflexilis, A. uncus spp. nov. In addition, A. cienka Dworakowska, 1982, n. comb.; A. decedens Paoli, 1932 and A. sakaii Dworakowska 1971, n. comb., are recorded from China for the first time. The following additional new combinations from Empoasca are also proposed: A. cisiana (Dworakowska, 1971); A. kaicola (Dworakowska, 1982), A. lutowa (Dworakowska, 1971), A. mona (Dworakowska, 1994), A. nipponica (Dworakowska 1982), A. rybiogon (Dworakowska, 1971), and A. uniprossicae (Sohi, 1977). Empoasca (Empoasca) kishtwarensis Sharma, 1984 is proposed as a new synonym of Asymmetrasca kaicola (Dworakowska, 1982). Habitus photos and illustrations of the male genitalia of the new species and a key to Chinese species are provided. New names are proposed to replace two junior homonyms in Empoasca (Matsumurasca).
