Abstract:

Two new species, Praeratavites rasnitsyni and Karatavites ningchengensis in the wasp family Karatavitidae, are described and illustrated. These specimens were collected from the uppermost Middle Jurassic Jiulongshan Formation at Daohugou Village in Inner Mongolia, China. Key venation characters, as measured by relative positions or length ratios, are summarized for all documented species of Karatavites and Praeratavites to facilitate morphological comparisons and assess whether the studied specimens are referable to new species. In addition, geometric morphometric analyses were conducted to confirm the distinction of the new species, which add to the diversity of these genera in the Middle Jurassic.
