Valve broad at base, sacculus scle- rotized, without terminal processes; costa band-like, curved, longer than the remaining part of the valva and distally separated from it, with a rounded tip. Sacculus and valve lamina setose. Transtilla a curved, continous band. Uncus with a broad base and a narrow, acute tip, curved ventrad. Anellus lobes elongate, conical, distally round- ed and setose. Aedeagus only a little longer than valve, slightly bent, distal one third covered with the densely spined part of manica (if not removed), vesica with four broad-based cornuti. Female unknown. Diagnosis. S. kuznetzovi is easily distinguished from oth- er members of the genus Scotopteryx by its peculiar ap- pearance and by a number of distinct characters (here com- pared mainly to members of the S. vicinaria-group, char- acters in round brackets): elongated forewings with glossy surface, rounded apex and tornus in kuznetzovi (forewings less elongated, not glossy, apex less rounded, angled or even slightly falcate; fig. 3); hindwing elongated-oval, much lighter than forewings and - except a medial band - without pattern (hindwings as dark as forewings and with much more pattern elements); antemedial and post- medial lines strongly waved and incurved, with deep in- cisions, sometimes medial band interrupted near hind mar- gin (transverse lines smooth or - in S. subvicinaria - slightly waved, not interrupted; fig. 3); transverse lines highlighted with black inside and white outside, a white submarginals line present (transverse lines not highlight- ed in this way, submarginal line unconspicuous); a
