Figures 16–19

Arctopscyhe irrorata Banks 1905: 217 , holotype 3 in AMNH; Flint 1961: 8, figs. 11–13 (larva); Nimmo 1987: 6 – 7, figs. 2 (wings), 13–18 (Ƥ,3); Wiggins 1996: 130 –131 (larva).

Diagnosis. The hind wing crossveins sc-r and r-rs are not coincident in their insertion on R, the insertions being separated by at least the length of crossvein r-rs. The female genitalia lack paired sclerotized projections internally.

Description. Wings ( Figs. 17 View FIGURE 17 , 28 View FIGURE 28 ): fwl = 16.5–20.5 mm; σ = 1.16 (N = 21). Fore-wings sub-hyaline, infuscate with mottling of yellow spots, shape typical for subfamily. Hind wings uniformly lightly infuscate, immaculate. Female genitalia ( Figs. 19–20): In cleared specimens in lateral view ( Fig. 19), abdominal segment IX anteriorly with strongly sloping lateral margins forming acute angle of approximately 45 with ventral sclerites; convex dorsum half as long as height of segment IX; in caudal view ( Fig. 20), dorsum convex. Prominent articulation ventrolaterally between segment IX and segment X, with segments IX and X strongly sclerotized. Segment IX posteroventrolaterally with pair of small sclerotized ridges (sr), each bearing row of setae. In ventrocaudal view of cleared genitalia, horseshoe-shaped sclerite present in dorsal membrane of segment X, located medially between dorsal processes (dp) of segment X. Cleared specimens internally and ventrally with weakly to moderately sclerotized curtain of membrane projecting anterad.
