摘　　要：描述哈格鸣螽科化石2新属7新种:Circulaboilus aureus gen.et sp.nov.,Circulaboilus amoenus gen.et sp.nov.,Furcaboilus excelsus gen.et sp.nov.,Aboilus stratosus sp.nov.,Aboilus cornutus sp.nov.,Pseudohagala shihi sp.nov.,Bacharaboilus jurassicus sp.nov.。标本采自于内蒙古宁城道虎沟中侏罗世九龙山组地层和辽宁西部晚侏罗世义县组地层,现保存于首都师范大学生命科学学院。In this paper two new genera and seven new species were described： Circulaboilus aureus gen. et sp. nov., Ciradaboilus amoenus gen. et gen. nov., Furcaboilus excelsus gen. et sp. nov., Aboilus stratosus sp. nov., Aboilus cornutus sp. nov., Pseudohagala shihi sp. nov. and Bacharaboilus jurassicus sp. nov. All of them were collected from Middle Jurassic, Jiulongshan Formation, Daohugou Village, Ningcheng Country, Inner Mongolia and Late Yixian Formation, Liaoning Province, China. Type specimens are deposited in Capital Normal University. Circulaboilus gen. nov. Type species： Circulaboilus aureus sp. nov. Etymology. Circul-（ from Latin arculi-, means round） ＋ aboilus （name of genus aboilus）, masculine. Diagnosis. Male, forewing oval. Fc long, arched, fused with precostal after 1/2 of the wing length. Precostal field broad. Sc straight, extending at about 3/4 of the wing length, with more than 10 branches leading to the anterior margin. R forked at about 1/2 of the wing length, R1 with 3 branches, Rs with 5 branches. R-M field wided at the medium of the wing. The basal part of M-Cu field wider than the basal part of Sc-R field. MP ＋ CuA1 forked earlier than R, with 4 branches. 1CuA2- 2CuA2 region and 2CuA2-CuP region wide. Female. Forewing oval. Fc long, arched, fused with precostal after 1/2 of the wing length. Precostal field broad. Sc straight, extending at about 3/4 of the wing length, with less than 10 branches leading to the anterior margin. R forked at 1/2 of wing length, R1 with 3 branches, Rs with 4 branches. R-M area narrow. The basal part of M-Cu field wider than the basal part of Sc-R field. MP ＋ CuA1 forked earlier than R, with 4 branches. Discussion. The new genus is similar to Bacharaboilus Gorochov, 1988, but it should be distinguished from the latter in following characters： Fc long, fused with precostal at about 1/2 of the wing length, Sc with few branches, Sc-R field wide, Rs beginning to branch near its base, MP ＋ CuA1 with less branches.
