Abstract
The earwig family Labiduridae occupies a putatively important position in the phylogeny of Dermaptera and is clearly of significant antiquity, with occurrences from the mid-Cretaceous and perhaps the Early Cretaceous. Nonetheless, palaeontological data on the family remains scant. Here we report a new genus and species of labidurids from mid-Cretaceous Kachin amber. Metaxylabis baii gen. et sp. nov. is described and figured, and its characters are compared with those of all other Mesozoic Labiduridae. The genus can be excluded from all of the current subfamilies of Labiduridae and is placed in its own subfamily, Metaxylabidinae subfam. nov. Remarks are given on the phylogenetic affinities of Mesozoic fossils and the need for more extensive sampling of palaeontological and genomic data.
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.
