Abstract
Cockroach Clypeblattula panda gen. et sp. n. is described from the Lower Cretaceous Laiyang Formation of Shandong Province, China based on a specimen with forewing and pronotum well-preserved. It is characterized by ovoid pronotum with two trapezoid dark stripes, forewing with intercalary space in R with colouration, A with six simple veins, and sparse cross-veins. It is closely related to the Early Cretaceous Pravdupovediac according to colouration of intercalary space in R, but they can be distinguished mainly based on the different wing shapes and the existence of dark macula. The differences between Clypeblattula gen. n., Ocelloblattula, Pseudomantina, Habroblattula and Laiyangia are also briefly discussed. The new genus is another indigenous cockroach of Blattulidae.
蜚蠊Clypeblattula panda gen. et sp. n.产于中国山东省下白垩统莱阳地层，以保存完好的前翅和前胸标本为基础进行了描述。它的特征是卵圆形的前翅上有两条梯形的暗色条纹，前翅的 R 部有夹层空间并带有颜色，A 部有 6 条单脉，横脉稀疏。根据 R 部中间空隙的着色情况，它与早白垩世的 Pravdupovediac 关系密切，但它们主要是根据不同的翅形和是否存在暗斑来区分的。此外，还简要讨论了 Clypeblattula gen. n.、Ocelloblattula、Pseudomantina、Habroblattula 和 Laiyangia 之间的差异。该新属是蜚蠊科的另一种本土蜚蠊。
期刊介绍：
Cretaceous Research provides a forum for the rapid publication of research on all aspects of the Cretaceous Period, including its boundaries with the Jurassic and Palaeogene. Authoritative papers reporting detailed investigations of Cretaceous stratigraphy and palaeontology, studies of regional geology, and reviews of recently published books are complemented by short communications of significant new findings.
Papers submitted to Cretaceous Research should place the research in a broad context, with emphasis placed towards our better understanding of the Cretaceous, that are therefore of interest to the diverse, international readership of the journal. Full length papers that focus solely on a local theme or area will not be accepted for publication; authors of short communications are encouraged to discuss how their findings are of relevance to the Cretaceous on a broad scale.
Research Areas include:
• Regional geology
• Stratigraphy and palaeontology
• Palaeobiology
• Palaeobiogeography
• Palaeoceanography
• Palaeoclimatology
• Evolutionary Palaeoecology
• Geochronology
• Global events.
