Is described in the present paper, which was collected from Early Cretaceous Lushangfen Formation (K41l) of Jingxi Basin in 1999. The new genus differs from all other lalacids in having the combined characters of tegminal venation: costal margin of tegmen straight and incrassated obviously; apical margin with sclerous striations; pterostigma well-developed; vein Sc 2-branched in the pterostigmal area; vein R1 simple and enclosing the posterior margin of pterostigma; CuA with 6 terminal branches; all crossveins thick obviously, r-m long and tegmen with 6 subapical and 14 apical cells. The holotype is deposited in the Beijing Forestry University. |
