Sasquacapnia Baumann & Broome , New genus

Type species Capnia (Bolshecapnia) sasquatchi ( Ricker, 1965) = Sasquacapnia sasquatchi (Ricker) by present designation

Male characteristics: Epiproct long, slender and curved dorsad near mid-length ( Figs. 56, 60 , 67, 71 ). A pair of dorsal sclerites arise from the epiproct base and extend forward for approximately a third or more of the epiproct length ( Fig. 57 , 72 ); sclerites narrow and may be acute at their tips. Epiproct narrows subapically and expands at the apex; apical area contains extrudable membranous material that may be partially or fully exposed ( Figs. 64 , 69 ). Abdominal terga without dorsal knobs; tergum 9 with patches of long setae ( Figs. 55 , 61 ).

Vesicle (n = 5). Oval in outline, constricted at the base and covered with thick setae ( Fig. 65 ).

Female characteristics: Subgenital plate usually reaching anterior margin of sternum 9; margin rounded and notched in S. missiona ( Fig. 66 ) and truncate in S. sasquatchi (fig. 14 in Baumann & Potter 2007).

Wings: As noted above, the wing venation for Sasquacapnia is indistinguishable from that of Bolshecapnia and Eurekapnia .

Larval characteristics: Unknown.

Current species: S. missiona , S. sasquatchi

Distribution: Known from British Columbia, Montana and Washington ( DeWalt et al. 2018).

Etymology: The generic name, Sasquacapnia , is based on “Sasquatchi”, a species name assigned by Ricker (1965) and formed from the name of the “yeti- like forest giants of the Fraser River valley

Salish Indian legends” ( Ricker 1965).
