Taxonomy of Sierola Cameron (Hymenoptera, Bethylidae) from China with three new species

Abstract

The genus Sierola Cameron, 1881 (Hymenoptera, Bethylidae) from China is revised for the first time and three new species, i.e., S. brevicaputasp. nov., S. limatulifasciasp. nov., and S. lelejisp. nov. are described. A key to the Oriental species is provided.

Two new chrysidoid wasps (Hymenoptera: Bethylidae, Chrysididae) from mid-Miocene Zhangpu amber

“…Gordh (1998) assumed that Sierola originates from continental Asia, before invading Hawaiian Islands, and rapidly radiated in a few million years while Magnacca (2020) proposed an Australian origin of the genus. Four species are known from China (Zhejiang Province and Macao, Wang, C. et al, 2021). Despite being apparently endemic of the circum-Pacific belt, two species have been described from the Upper Eocene Baltic and Rovno ambers: Sierola hastata Sorg, 1988 and Sierola rovniana Ramos and Azevedo in Ramos et al, 2014.…”
