New horseflies and water snipe-flies (Diptera: Tabanidae and Athericidae) from the Lower Cretaceous of China

A new tabanid Laiyangitabanus formosus gen. et sp. nov. and a new athericid Sinocretomyia minuscula gen. et sp. nov. are described based on two female impressions from the Lower Cretaceous of the Laiyang Formation in Laiyang, Shandong, China. The systematic positions for “Allomyia” ruderalis Ren, 1998, Eopangonius pletus Ren, 1998 and Palaepangonius eupterus Ren, 1998 are reassessed. These should belong respectively to Archisargidae, subfamily uncertain of Tabanidae and Athericidae rather than to the Tabaninae and Pangoniinae of Tabanidae.
