Two New Acantholyda Species from Gansu Xinglong Mountains(Hymenoptera:Pamphiliidae)
[Objective]To identify and report two new species of Pamphiliidae collected from Xinglong Mountains,Gansu Province,to help the identification and control of forest pests.[Method]The speci-mens of the two new species were collected from Xinglong Mountains,Gansu Province.The morphologic-al characteristics of the new species were observed based on morphological taxonomy.Figures were illus-trated.Similar species of the new species were studied.[Result]The two species were confirmed to be new to science of Pamphiliidae,Hymenoptera:Acantholyda bimaculoclypea Wei,sp.nov.,A.leuconervis Wei,sp.nov.The species were described in detail and illustrated.The types were designated and kept in the Asian Sawfly Museum,Nanchang.The differences between the new species and their relatives were also remarked.A key to known species of Acantholyda from Gansu was also proposed.[Conclusion]Based on the morphological study,the two species were confirmed to be new species of Acantholyda,Pamphiliidae and described in detail.
