Revision of the World Species of Timberlake (Hymenoptera: Trichogrammatidae).

species are important models for basic organismal research, and many are potential biological control agents. We present the first extensive revision of species of the genus based on morphological and molecular data. Our revision includes all previously described species, 6 of which are synonymized, and 22 of which are described here as new. We also provide the first key to all species of the genus and reconstruct their phylogeny based on 28S and CO1 molecular markers. The following species are synonymized with Subba Rao: Yousuf and Shafee ; Viggiani ; Lin ; Yousuf and Shafee ; Hayat Yuan and Lou is synonymized with Lin.
