“…Hyalopterus is morphologically characterized by an elongated shape, antennae shorter than the body, and siphunculi shorter than cauda without flange and rounded at apex (Zhang & Zhong, 1983). Numerous researchers have focused on the taxonomy of this group over the last century (Eastop, 1966;Favret, Meshram, Miller, Nieto Nafria, & Stekolshchikov, 2017;Lozier et al, 2008;Moreno-Gonzalez & Nieto Nafria, 2018;Poultos et al, 2007;Rakauskas et al, 2013;Smith, 1936). Recent revisionary attempts to resolve the species boundaries within Hyalopterus have made progress partly as a result of the rapid introduction and spread of the invasive species H. pruni across North America (Lozier, Roderick, & Mills, 2009), as well as from a general interest in speciation mechanisms, host-associated gene expression and so on (Cui, Yang, Guo, Kang, & Cui, 2017;Lozier et al, 2007).…”
