Description and type material. Blank et al. (2013) . Host . Imagines have repeatedly been swept from Pinus pumila ( Blank et al. 2013 ; present data), but the immature stages are still unknown. Distribution. Subalpine zone of Hokkaido ( Blank et al. 2013 ; this work). Records. Hokkaido : Engaru-machi , Mt Murii-dake , Tozan-one , [ 43.733°N 143.177°E ], 1500–1876 m altitude, 3.7.2011 , leg. K. Haga , 1♀ , DEI-GISHym 22103, swept from Pinus pumila foliage, NSMT ; Furano-shi , between Kumomine-yama and summit of Mt Ashibetsu-dake , [ 43.236°N 142.283°E ], 4.7.2001 leg. K. Haga , 2♀ 3♂ , swept from foliage of Pinus pumila , NSMT , SDEI ( 1♀ DEI-GISHym 22106, 1♂ DEI-GISHym 22105); Kamishihorocho , near summit of Mt Mikuni-yama , [ 43.596°N 143.147°E ], 26.6.2008 , leg. K. Haga , 1♀ , DEI-GISHym 22104, swept from foliage of Pinus pumila , NSMT ; Kamishihoro-cho , south ridge of Mt. Upepesanke-yama , [ 43.382°N 143.099°E ], 1610–1830 m altitude, 13.7.1995 , leg. K. Haga , 3♀ , swept from foliage Pinus pumila , NSMT ; Shimizu-cho , Mt. Memuro-dake , main peak to west peak [ 43.872°N 142.779°E ], ca. 1700 m alt., 20.7.1999 , leg. K. Haga , 1♀ , swept from foliage of Pinus pumila , NSMT . Remarks. The observation that two of three initially known specimens of X. pumilae were collected from P. pumila was surprising ( Blank et al. 2013 ). Xyela pumilae is classified as belonging to the X. julii group, which generally has Pinus ( Pinus ) species as the larval hosts, while P. pumila is placed in Pinus ( Strobus ) ( Eckenwalder 2009 ; Farjon 2010 ). The unusual association of X. pumila with P. pumila now seems to be corroborated by complementary collection data from five sites, where imagines were again swept from this pine species.
