摘要

根据白垩纪中期克钦琥珀中的一个保存完好的雄性标本，我们描述了一种新的蠼属及其模式种--Prodacnodes dupliforceps gen.Prodacnodes具有独特的组合特征：复眼大、花葶短于复眼长度、前胸与头部等宽、前胸近梯形、翅存在且发育完全、跖骨Ⅱ顶部不倾斜、腓骨具短的中间突、雄性外副趾中侧具突出的近尖端齿以及简单的镊子。我们的研究提供了更多的形态特征和信息，丰富了我们对中生代晚期蠼螋种系和多样性的理解。

A new lineage of pygidicranid earwigs from mid-Cretaceous amber of northern Myanmar (Dermaptera: Pygidicranidae)

Based on a well-preserved male specimen from mid-Cretaceous Kachin amber, we describe a new genus and its type species of earwig, Prodacnodes dupliforceps gen. et sp. nov. Prodacnodes has a unique combination of traits: large compound eyes, scape shorter than compound eye length, pronotum as broad as head, prosternum subtrapezoidal, wings present and fully developed, metatarsomere II not slanted apically, pygidium with short medioapical process, male external parameres with prominent subapical tooth mesally, and simple forceps. Our research contributes additional morphological features and information, enriching our comprehension of the lineages and diversity of Late Mesozoic earwigs.

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.
