Diagnosis (Figs. 1B, 2B, 5, 6). For morphological differences between S. fusca sp. nov. and S. amurensis, see ‘Diagnosis’ for S. fusca sp. nov..
Redescription. Length of forewing 14.0–18.0mm; forewing expanse 26.0–36.7mm. Head, thorax and abdomen resembling those of S. fusca sp. nov., but different as follows: Vertex and face roughly clothed with yellowish white long hairs.
Wing markings (Fig. 1B): Forewing and hindwing resembling those of S. fusca sp. nov., but different as follows: Forewing upperside bordered with yellowish white along dorsum and termen. Hindwing upperside pale brownish white.
Wing venation (Fig. 2B): Wing venation resembling that of S. fusca sp. nov.
Male genitalia (Fig. 5): Male genitalia resembling those of S. fusca sp. nov., but different as follows: Width of base of uncus similar to length of uncus. Gnathos and subscaphium absent. Vinculum broad; saccus broad with rounded apex. Valva 1/2 as wide as height of ring, valval apodeme 1/4 times as long as length of valva. Carina of phallus projecting.
Female genitalia (Fig. 6): Female genitalia resembling those of S. fusca sp. nov., but different as follows. Genital plate with a pair of rounded quadrate lamellae; apical 1/4 of digitiform process extending beyond posterior margin of genital plate.
Distribution. Japan: Hokkaido, Honshu (Aomori, Iwate, Nagano and Nara Prefs.), Russia (Amur, Primorsk).

Sampling localities of Scardia species are shown in Fig. 7.
Remarks. The male genitalia of Scardia amurensis and S. fusca sp. nov. are similar to those of S. boletella and S. caucasia, in lateral view, but the uncal lobes are slenderer, and not stout as in S. boletella and S. caucasia. In addition, in the two Japanese species, the digitiform processes of the female are slenderer than those of other Scardia species.
