摘　　要：描述原哈格鸣螽科化石1新属5新种:奇异阿波鸣螽属Allaboilusgen.nov.,二叉奇异阿波鸣螽Allaboilusdicrussp.nov.,巨大奇异阿波鸣螽Allaboilusgigantussp.nov.,林氏原阿波鸣螽Protaboiluslinisp.nov.,野生原阿波鸣螽Protaboilusrudissp.nov.及模糊原阿波鸣螽Protaboilusamblussp.nov.。化石标本采于内蒙古宁城中侏罗世九龙山组及河北丰宁晚侏罗世义县组。In this article, one new genera and five new species were described. The specimens described were collected from Jiulongshan Formation, Inner Mongolia and Yixian Formation, Hebei Province. All fossils described here were deposited in Capital Normal University. Allaboilus gen. nov. Type species： Allaboilus dicrus sp. nov. Diagnosis. Forewing wide, Fc strong, arcked. Sc terminated on the anterior margin, with less than 15 branches. Rs ＂S＂ shaped, with 7 branches. MA straight. The basal part of R-M field wider than the basal part of Sc-R field. The first branch of MP ＋CuA1 forked again. The width of the basal part of M- Cu field equal to the basal part of Sc-R field. Discussion. Only one genus Protaboilus Gorochov, 1988 has been published in this subfamily. The new genus could be distinguished from the latter by the following characters： forewing wide, branches of Sc less than 15, Rs with 7 branches, first branch of MP ＋ CuA1 forked again. Etymology. /kilo- （from Greek word allo-, means special） ＋ aboilus （ name of genus Aboilus ）, masculine. Allaboilus dicrus sp. nov. （Figs. 1,4） Holotype. A well preserved forewing of female insect, registration No. CNU-O-NN- 2006001. Locality and horizon. Middle Jurassic, Jiulongshan Formation, Ningcheng, Inner Mongolia. Description. Forewing length 49 mm, width 29 mm, stout. Etymology. From Greek word dicrus （forked）. Allaboilus gigantus sp. nov. （Figs. 2,5） Holotype. A well preserved forewing of male insect, registration No. ： CNU-O-NN-2006002-1, CNU-O-NN-2006002-2. Locality and horizon. Middle Jurassic, Jiulongshan Formation, Ningcheng, Inner Mongolia. Description. Forewing length 69 mm, width 29 mm （as preserved）. The remain part is rather well preserved. Discussion. The new species is differed from A. dicrus by the following characters： Fc terminated on Sc before forking point of the first branch of R1. Etymology. From Greek word gigantus, referring to the wing very big in size. Protaboilus
