摘要：

The Blattulidae is an extinct family of cosmopolitan Mesozoic cockroaches with a low generic diversity. Habroblattula laiyangensis sp. nov. from the Lower Cretaceous Laiyang Formation of Shandong Province of China with well-preserved both hind wings is only closely related to the H. drepanoides Wang, Liang & Ren, 2007 from the Early Cretaceous Yixian Formation, sharing the venation pattern, while being significantly smaller, and provides new characteristics of ancient Blattulidae. In addition, H. laiyangensis sp. nov. resembles distribution patterns of a closely related complex of "Piniblattella" yixianensis Gao, Shih & Ren, 2018 with "Mesoblattina" sinica Ping, 1928, suggesting a spatiotemporal paleobioprovincial relation among Laiyang and Yixian formations, former probably representing more warmer southern localities. Laiyangia Grabau, 1923 and Sinoblatta Grabau, 1923 are indigenous to Laiyang and lack analogues also in numerous Cretaceous Mongolian and Russian sites evidencing a degree of isolation.
