摘　　要：描述原哈格鸣螽科化石1新属:糙哈格鸣螽属Trachohaglagen.nov.,4新种:热河糙哈格鸣螽Trachohaglajeholiasp.nov.,阔翼赤峰鸣螽Chifengialatasp.nov.,渐狭赤峰鸣螽Chifengiaangustatasp.nov.,阔基线哈格鸣螽Grammohaglalatibasissp.nov.。所有化石标本均采于辽宁西部晚侏罗世义县组地层,现存于首都师范大学生命科学学院。In this article, one new genus and four new species were described and illustrated. All the type specimens described here were collected from the Late Jurassic Yixian Formation, Liaoning Province, China, and deposited in Capital Normal University. Trachohagla gen.nov. Type species： Trachohagla jeholia sp. nov. Diagnosis. Forewing Fc （False Costal） indistinct. Sc straight, with 10 branches. Rs with at least 6 branches. MP meet with CuA1 just on a point and then leave immediately, never fuse with it for a long distance. The basal part of M-Cu field is wide-thAn the basal part of Sc-R field. MP ＋ CuA1 forks early than R. MP ＋ CuA1 with at least 3 terminal branches. Discussion. This new genus is distinct from Ashanga Zherikhin, 1985 and Aethehagla Meng et Ren, 2006 by Fc strongly degenerated. The new genus is somewhat similar to Parahagla Sharov, 1968, Chifengia Hong, 1982, Hebeihagla Hong, 1982, Habrohagla Ren, 1995 and Grammohagla Meng et Ren, 2006. However, it could be distinguished by the following character： MP meet with CuA1 just on a point and then leave immediately, never fuse with it for a long distance. Etymology. Trach- （from Greek： Trach-, means rough） ＋ hagla （name of genus hagla ）, feminine. Trachohagla jeholia sp. nov. （Figs. 1, 4） Holotype. A partly preserved fore-wing of male insect. Registration No. CNU-O-LB-2006008. Locality and horizon. Late Jurassic, Yixian Formation, Beipiao City, Liaoning Province. Description. Forewing length 32 mm, width 6 mm （as preserved）. The details are shown in Figs. 1, 4.. Chifengia lata sp. nov. （Figs. 2, 5） Etymology. Lata from Latin, means wide. Holotype. A well preserved forewing of female insect. Registration No. NU-O-LB-2006009. Locality and horizon. Late Jurassic, Yixian Formation, Beipiao City, Liaoning Province. Description. Length 34 mm, width 18 mm （as preserved）. The forewing zonally spotted. Fc indistinct. Sc ＂S＂ shaped, with 10 branches. R1 with 4 branches, Rs with about 6 bran
