Key to North American Dodia species

1 Forewing an even, translucent grey, without transverse bands; width of male valve at midpoint greater than ¼ total length of valve; vesica with two clusters of spines, one at apex and one at base; female corpus bursae slightly constricted medially.................................................................... D. kononenkoi

– Forewing with light and dark transverse bands; width of male valve at midpoint ¼ or less total length of valve; vesica with single apical cluster of spines ( Figs. 6, 7 ); numerous smaller peg-like spinules may also be present ( Fig. 6 ); female corpus bursae oval, wider posteriorly than anteriorly........................ 2

2 Forewing transverse bands meeting posterior margin at right angles; known only from dry, rocky tundra habitat in the Yukon (male unknown) ............. ................................................................................................. D. verticalis

– Forewing transverse bands meeting anal margin at acute angle, running more or less parallel to outer margin; occurring in wet tundra and boreal peat bogs ............................................................................................................ 3

3 Forewing and thorax markings varying from nearly unmarked to moderately contrasting (subapical pale dash always contrasting), but never with basal and antemedial area paler than outer half of wing ( Fig. 1 ); male valve apex with two short, blunt projections ( Fig. 4 ); juxta wider than long ( Fig. 4a ); inflated vesica approximately as long as aedeagus ( Fig. 6 )......................... D. albertae

– Forewing and thorax contrastingly marked in mouse grey and whitish-grey banding, with basal and antemedial area noticeably paler than outer half of wing ( Figs. 2 , 3); male valve apex strongly bifurcate, with 2 longer narrower prongs ( Fig. 5 ); juxta longer than wide ( Fig. 5a ); inflated vesica 2/3 or less length of aedeagus ( Fig. 7 ) ........................................................ D. tarandus
