Abstract

Two new species of Archidermaptera are described and figured from the Middle Jurassic Jiulonghsan Formation of Daohugou, Inner Mongolia, China. Aneuroderma oiodesgen. & sp. nov. is described in the family Protodiplatyidae and Sinopalaeodermata concavumsp. nov. is established in the family Dermapteridae. Both new species share the typical characters of the extinct suborder Archidermaptera (e.g., pentamerous metatarsi, filiform and multimerous cerci, externalized ovipositor). Aneurodermagen. nov. is compared with other genera of the Protodiplatyidae, while S. concavumsp. nov. allows us to emend the diagnosis of the genus Sinopalaeodermata. We briefly discuss the diversity of Archidermaptera and challenges to understanding relationships among this mid-Mesozoic diversity.
