Iteaphila polygyna (Melander) comb. nov. (Figs 68, 74) Anthepiscopus polygynus Melander, 1928: 105. Type locality: Deer Park, Washington, USA. Anthepiscopus flavicoxa Melander, 1928: 107. Type locality: Kettle Falls, Washington, USA. syn. nov. Type material examined. Anthepiscopus flavicoxa: HOLOTYPE ♀, labelled: “ Kettle Falls [48°36′21″N 118°3′35″W],/ 8 May’ [19]12 Wash ”; “ TYPE / Anthepiscopus / flavicoxa/ Mel. [red label]”; “ALMelander/ Collection / 1961” (USNM). Anthepiscopus polygynus: LECTOTYPE (here designated in order to fix identity of the species), ♂ labelled: “Deer Park [47°57′25″N 117°28′13″W],/ 5.v.[19]12Wash”, “ TYPE ♂ / Anthepiscopus / polygynus/ Mel. [red label]”; “ALMelander/ Collection/ 1961”; Anthepiscopus / polygynus/ ♂ Mel.”; “ LECTOTYPE / Anthepiscopus / polygynus Melander / des. B.J. Sinclair 2020 [red label]” (USNM). PARALECTOTYPES: Same data as holotype (6 ♀, USNM). Notes on synonymy. Melander (1928) distinguished A. flavicoxa and A. polygynus on the basis of female leg colouration. The coxae and femora are yellowish in the former species and females in the type series of polygynus are all dark legged. A short series from Salmon Arm (Canada, BC), which included males matching polygynus and yellow-legged females similar to flavicoxa, clustered together in the barcode analysis (Fig. 82). Given this additional evidence, these two species are considered conspecific and it can be assumed that female leg colouration in this species is variable. Additional material examined. CANADA.
