Distribution . Japan (new record): Hokkaido , Honshu. Palaearctic (see Sundukov, 2017 , for details), N. America (introduced; Forbes and Daviault, 1964 ). Host plants . Rosaceae : Sorbus commixta Hedl. (new record). This species is associated with various species of Sorbus . For the host plants outside Japan , see Prous et al. (2017) . This sawfly is well known as a pest in North America ( Forbes and Daviault, 1964 ; Looney et al. , 2016 ). Remarks . This Palaearctic species is here recorded from Japan for the first time. The Japanese females and males go to Pristiphora geniculata in the key to North-Western Palaearctic species of Pristiphora by Prous et al. (2017) . Their lancets and penis valves are identical with those of European specimens respectively (compare Fig. 12A, E with figs. 150, 229 in Prous et al. , 2017 ). The final instar larva of Japan ( Fig. 12G ) is also almost the same as the European larva figured by Macek et al. (2020 , p. 537, fig. 4).
