Parapiophila atrifrons (Melander & Spuler) Piophila atrifrons Melander & Spuler, 1917: 66 (type locality: United States of America. Idaho: Troy). Allopiophila calceata Duda, 1924: 174 (type locality: Sweden: Gällivare and Abisko), syn. n. NBP/NIS material examined. 9 ♂, 9 ♀ from the following sites: Manitoba: Churchill; Northwest Territories: Norman Wells; Nunavut: Kugluktuk; Ontario: Moosonee; Quebec: Schefferville (vi.1952, 1962; vii.2010, vi–vii.2011; viii.1952) (CNC, LEM). Other material examined. Lectotype of P. atrifrons: 1 ♂ labelled Troy, Idaho, 14.vi.08, Paratype Piophila atrifrons M-S, Lectoholotype P. atrifrons, d. G Steyskal 1963, Lectotype Piophila atrifrons Melander, Spuler, 1917: 66, by Steyskal, 1964: 177, det. A Ozerov, 2002 (USNM). Paralectotypes: UNITED STATES OF AMERICA. Washington: Oroville, Paratype M.-S., Paralectotype, Melander et Spuler, 1917: 66, det. A.L. Ozerov 2003, USNM ENT 01071201, (1 ♀, USNM); Oroville, Type M.-S., Paralectotype, Melander et Spuler, 1917: 66, det. A.L. Ozerov 2003, USNM ENT 01071192, (1 ♀, USNM). Comments. Parapiophila atrifrons is widespread in northern Canada and the northern United States (Washington, Idaho, Maine) (Melander & Spuler 1917; McAlpine 1977). It is also known from the Palaearctic region (McAlpine 1977; Ozerov 2004b). Steyskal (1964) suggested that Allopiophila calceata might be conspecific with Parapiophila atrifrons but that examination of more specimens would be required. We examined 185 specimens of both species from CNC and LEM. The only reliable difference between A. calceata and P. atrifrons is the shape of the tip of the pregonite: one round and one pointed tip in P. atrifrons; two pointed tips in A. calceata (McAlpine 1977). The male genitalia are otherwise identical, and the minor difference in the pregonite may not be enough to justify two species. Parapiophila nitidissima (Melander & Spuler) has variation in the shape of the pregonite tip (Steyskal 1975). There is variation in the colour of the fore tibia in some ...
