Abstract

A new genus and species of earwig is described and figured from Early Cretaceous (Latest Albian­Earliest Cenomanian) amber of southwestern France. The holotype was studied using traditional light microscopy as well as through propagation phase contrast X-ray synchrotron microtomography, rendering high resolution three-dimensional models for critical examination. Gallinympha walleri Perrichot & Engel, new genus and species, is represented by two late instar nymphs missing only portions of the abdomen, as well as most of the head for the paratype. The genus is a member of the Pygidicranidae, one of the most basal of living earwigs, and is distinguished from other taxa in the family. A thorough account of the specimen's morphology is provided along with a detailed comparison with similar structures across a diversity of primitive earwig lineages.
