A second cuckoo wasp species from the mid-Miocene Zhangpu biota (Hymenoptera: Chrysididae)

The Miocene history of the aculeate family Chrysididae is poorly known, with only two species described for that time interval. Here, a third species is introduced, the second from the rich middle Miocene Zhangpu amber, southeastern China. †Trichrysis perrichoti n. sp. is described and illustrated based on a nearly complete female specimen. The new species displays characters of the cyanea species group, which is today the most common for Trichrysis Lichtenstein, 1876 in China. This discovery further strengthens the affinities between the Zhangpu entomofauna and the modern Southeast Asia entomofauna.
