Resumen

Summary: Fossils of the early-diverging neodermapteran families Diplatyidae and Haplodiplatyidae are rare, and for the latter have confined to a single Miocene occurrence. Here we report a new genus and species of haplodiplatyid earwig in mid-Cretaceous amber from southern Asia. Zeugmadiplatys chenin. gen., n. sp. shares many features with extant Haplodiplatys Hincks, 1955, especially the simple, dentiform metaparameres of the male genitalia, but differs notably in the development of the compound eyes, antennae, abdominal tergites and sternites, and ventrally flattened cercal forceps with weakly crenulate to serrate mesal margins. The discovery of the new fossil extends the fossil record of Haplodiplatyidae by approximately 80 million years and provides a crucial calibration point for divergence-time estimates in the diversification of Neodermaptera.
