Two new species of Dolerinae from Mt.Liupan,Ningxia of China are described:Dolerus liupanicus Wei sp.nov.and D.xiai Wei sp.nov.Dolerus liupanicus is similar to D.purus Jakovlev,1891 but differs from it by the pronotum,tegula,mesoscutal middle lobe and the first abdominal tergum entirely black,the setae of apical sheath almost straight and extending outward at an angle of about 100 degrees,the alaspiculae of middle annuli very large,the middle serrulae each with about 14 to 15 small subbasal teeth.Dolerus xiai is similar to D.japonicus Kirby,1882 but differs from the latter by the fore wing deeply infuscate,the mesepisternum and legs entirely black,the setae on apical sheath blackish brown,the apical sheath in lateral view narrow and strongly tapering toward apex,the middle carina on mesoscutellar appendage not concave,the male abdomen with broad reddish brown rings,and the dorsal apical corner of penis valve convex.A key to species of Dolerinae from Mt.Liupan and nearby area is also provided. 展开更多

A new species of the Macrophya sibirica group, Macrophya harbina Li, Liu Wei sp. nov. from China is described. This new species is similar to M. revertana Wei, 1998, but differs from the latter in the posterior margin of pronotum and center of mesoscutellum white; postocellar area 1.5 times broader than long;mesepisternum not entirely black, center of posterior margin with a small white macula; mesepisternum minutely and densely punctured, not coarse, interspaces between punctures distinct; dorsum of mesoscutellum without carina, with very sparse and shallow punctures; hind femur largely black, base with white macula on dorsal side; posterior margin of abdominal tergum 1 with distinct white maculae; middle serrulae of lancet each with 2 proximal and 9–11 distal teeth. A key to all known species of the Macrophya sibirica group from China is provided. 展开更多
