摘要

A new genus and species, Gracilipygia canaliculata gen. et sp. nov., in the family Pygidicranidae of Dermaptera is described from the Upper Cretaceous Myanmar amber. The new species is assigned to the subfamily Pyragrinae mainly based on the following characters: broadly separated cercal forceps without segmentation and the posterior abdominal tergum with mediolongitudinal furrow and lateral ridges. The G. canaliculata gen. et sp. nov. is the earliest record hitherto for the subfamily Pyragrinae, and probably represents a stem taxa of Pyragrinae.
