由北京市科学技术研究院“北科青年学者”项目(Grant No. YS201902)、天津市“五个一”项目、国家自然科学基金项目(31730087、41688103和32020103006)项目资助，国家自然博物馆与天津自然博物馆及首都师范大学研究人员共同研究我国内蒙古道虎沟地区的蜚蠊目小蠊科昆虫化石，其研究成果发表在斯洛伐克著名的生物学杂志Biologia。

蜚蠊俗称蟑螂，论文研究的标本隶属于蜚蠊目小蠊科，为已绝灭类群。伪螳属由斯洛伐克古生物学家 Sendi 和 Vršanský于2021建立，包括2种，分别为Pseudomantina occisor和P. nigroalba。本论文根据研究建立一新种为白居易伪螳Pseudomantina baijuyii，种名献给白居易先生。白居易伪螳前翅几乎被色斑覆盖，仅有前翅前缘部分无色斑，犹如白居易的诗“千呼万唤始出来，犹抱琵琶半遮面”

白居易伪螳为该属已知最古老的种类，为1.6亿年前的中侏罗世，其余两个物种分别来自晚侏罗世（哈萨克斯坦）和早白垩世（黎巴嫩）。

Abstract：

Species of Pseudomantina Sendi et Vršanský, 2021 in the family of Blattulidae Vishniakova, 1982, the peculiar and possibly predatory cockroach genus, have been reported from Upper Jurassic Karatau compression sedimentary fossils site and Barremian Lower Cretaceous Lebanese amber. Pseudomantina baijuyii Liang, Wang, Shih et Ren, sp. n. from Daohugou, Inner Mongolia, China in the Middle Jurassic Jiulongshan Formation is diagnosed with simple Sc, ovoid pronotum, A with six simple veins, not forked, lack of diagonal kink at clavus, and peculiar coloration patterns on forewing. This new species is differentiated from P. nigroalba Vršanský, 2021 which have five simple anal veins, not forked, and also from P. occisor Sendi, 2021 which have five anal veins.
