Fig. 4 View Fig .
Etymology: The specific name epunctatus refers to the immaculate hindwing of the new species.
Holotype: CNU−NEU−NN2010208 ( Fig.4a View Fig ). Well preserved hindwing. Type locality: Daohugou Village , Shantou Township, Ningcheng County, Inner Mongolia, China.
Type horizon: Jiulongshan Formation, Aalenian–Bajocian boundary, Middle Jurassic.
Diagnosis.—Only hindwing preserved; membrane hyaline, immaculate; cells in MP region arranged irregularly; CuP with 12 pectinate branches.
Description.—Only the hindwing preserved, 25.2 mm long, 7.5 mm wide ( Fig. 4A View Fig ). Membrane hyaline, nearly immaculate; pterostigma pale brown, nygmata not detected; trichosors welldefined in the posterior margin of wing; costal cross−veins simple; Sc and R1 entering the margin before the apex; cross−veins r1−rs numerous; Rs originated from R1, with 20 branches, distal branches slightly sinuous; cross−veins in radial area numerous, arranged irregularly; MA originated from Rs−stem as most osmylids; MP forks close to the wing base, MP region greatly broadened, forming two rows of cells, cells in MP region arranged irregularly, cross−veins slightly sinuous from middle to termination; MP 1 and MP 2 forming simple pectinate distal branches; CuA long, with 13 pectinate branches; CuP short, as long as the half of CuA, with 12 pectinate branches; A1 well−developed, with 7 pectinate branches ( Fig. 4B View Fig ).
Remarks.— Jurakempynus epunctatus sp. nov. is conveniently separated from other species by the following characters: hindwing immaculate, while other species commonly have large spots on margin; cells in MP region arranged irregularly, only forming two rows of cells in middle, while other species generally forming two rows of cells on the whole MP region.
