This dataset contains the digitized treatments in Plazi based on the original journal article Cao, Liang-Ming, Xie, Ji-Yu, Wang, Xin-Geng, Wang, Xiao-Yi, Poland, Therese M., Petrice, Toby R., Yang, Zhong-Qi (2024): Description of a new species of the genus Atanycolus Foerster (Hymenoptera: Braconidae) parasitizing Lamprodila nobilissima bellula (Lewis) (Coleoptera: Buprestidae) in China. Zootaxa 5448 (2): 248-260, DOI: 10.11646/zootaxa.5448.2.5, URL: http://dx.doi.org/10.11646/zootaxa.5360.3.8AbstractAtanycolus yangi sp. nov. (Hymenoptera, Braconidae), a new species parasitizing the flatheaded wood borer, Lamprodila nobilissima bellula (Lewis) (Coleoptera: Buprestidae), is described. Lamprodila nobilissima bellula is a serious wood boring pest of Rosacea trees in North China. We collected adult specimens of A. yangi sp. nov. searching for hosts on infested tree trunks and confirmed the host-parasitoid association by dissecting parasitized hosts from infested trees in the field and rearing the parasitoid from L. nobilissima bellula - infested host tree logs in the laboratory. Adult images for both sexes of the new parasitoid species are provided. A morphological identification key to Oriental and Palaearctic species similar to A. yangi sp. nov is also presented.
