Introduction malaisei-group; planata-group; regia-group; sanguinolenta- group; sheni-group; sibirica-group; vittata-group and Macrophya Dahlbom, 1835 (Hymenoptera, Tenthredinidae, zhaoae-group. Tenthredininae, Macrophini) is the third largest genus in In the regia group of Macrophya, three species were Tenthredininae and the fourth largest of Tenthredinidae. reported from China to date, i.e., M. regia Forsius 1930, M. The genus is chiefly distributed in the north of the Oriental, maculoclypeatina Wei et al. 2003, and M. xiaoi Wei et al. Nearctic, and Palaearctic regions. At present, 289 species 2003. In the present paper two new species of the regia group have been described by the end of 2017 (Taeger et al. of Macrophya are described and illustrated from China: M. 2010; Zhao et al. 2010a, 2010b; Zhao & Wei 2011; Li acutiserrula Li, Liu & Wei sp. nov. and M. frontalis Li, Liu et al.2012;Wuet al.2012;Zhuet al.2012;Weiet al. &Zhusp. nov.TheMacrophya regia group is proposed and 2006, 2013; Li & Wei 2012, 2013; Li et al. 2013a, defined for Chinese species, and a key to the five known 2013b, 2013c, 2014a, 2014b, 2016a, 2016b, 2017a, species of regia-group of Macrophya is provided. 2017b, 2018; Liu et al. 2015a, 2015b, 2016a, 2016b, 2017a, 2017b; Shinohara 2015; Shinohara & Li 2015; Shinohara & Yoshida 2015). In China, 150 species of Materials and methods Macrophya have been recorded. Macrophya includes 27 species groups worldwide (Li The specimens were examined with a Motic-SMZ-168 et al. 2014a, 2014b, 2018). In China, it includes 20 species dissection microscope. Adult images were taken with a groups: the annulitibia-group; apicalis-group; bland-group; Nikon D700 digital camera and a series of images coxalis-group; crassuliformis-group; duodecimpunctata- montaged using Helicon Focus (HeliconSoft, Kharkiv, group; flavomaculata-group; formosana-group; histrio- Ukraine). All images were further processed with Adobe group; imitator-group; ligustri-group; maculitibia-group; Photoshop CS 11.0.

Morphological descriptions of new species are based on the In China, the Macrophya regia species group includes three holotype. The terminology of genitalia follows Ross (1945) known species and two new species described here. They can and that of general morphology follows Viitasaari (2002). be separated using the following key. For a few terms (e.g. middle fovea and lateral fovea), we follow Takeuchi (1952).
