Iteaphila polygyna Sinclair & Shamshev 2021, comb. nov.

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.

Proepisternum with a few hair-like setae. Postpronotal lobe with 1 long and several short setae. Mesonotal setae distinct, thin; acr moderately long, biserial, arranged in 2 closely spaced irregular rows, lacking on prescutellar depression, distance between rows subequal to length of acr; dc uniserial (with some additional setulae in anterior part), offset from row anteriorly, slightly longer than acr, 2–3 distinct prescutellar dc; 1 ph, 1–2 presut spal (sometimes with additional setulae), 3–4 npl (with several additional shorter setae), several psut spal setulae, 1 pal and several short setulae, 6–7 pairs of sctl. Legs, including coxae, mostly brownish; knees of fore and mid legs brownish yellow, tarsi somewhat darker. Coxae and trochanters with unmodified hair-like setae. Fore femur with row of short anteroventral hair-like setae and somewhat longer setae on posteroventral, dorsal and posterior faces.

Cercus long, broad, two-thirds length of epandrium; apex broadly rounded, extended free from epandrium; hypoproct produced into pair of long, slender processes, projecting beyond cercus. Female. Similar to male, except as follows: Eyes dichoptic, ommatidia equally small. Frons very broad, somewhat widened toward ocellar triangle, subshiny with fine greyish pruinescence, with quite long marginal setulae. Scutellum with 8 pairs of setae. Legs (including coxae) usually varying from yellow to dusky yellow to darkened leaving only knees distinctly yellow; fore and mid femora with some short, hardly prominent posteroventral subapical setae.
