| 摘 要： | 报道产于北京西山门头沟区色树坟石炭-二叠系太原组的一块蜚蠊类前翅化石,可归入Phyloblatta,代表一新种Phyloblatta beijingensis sp. nov.,以狭小的爪区别于该属其他已知种类。Phyloblatta蜚蠊类在我国山西省下二叠统山西组曾发现多种类型。对北京地区以前报道的昆虫化石所属时代和地层均进行厘定,如土城子组、大灰厂组、夏庄组的昆虫化石。

| Abstract: | Here we report a new species belonging to the extinct genus Phyloblatta, Phyloblatta beijingensis sp. nov. , from the Carboniferous-Permian Taiyuan Formation at Seshufen, Mentougou District (Xishan, Beijing) based on a dictyopteran forewing. The new species can be readily separated from other congeners mainly by its prolate clavus. Diverse Phyloblatta dictyopterans have been discovered from the Lower Permian Shanxi Formation in Shanxi Province. The age and biostratigraphy of the insect-yielding formations in Beijing, such as the Tuchengzi, Dahuichang and Xiazhuang formations, are also discussed. |
