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. FIGURE 5 . Male genitalia of S. amurensis . A: whole genitalia except aedeagus, lateral view. B: Uncus, dorsal view. C: Genitalia except valva, ventral view. D: Valva, inner view. E: Anellus and juxta, lateral view. F: Aedeagus, lateral view. G: Ditto , dorsal view. FIGURE 6 . Female genitalia of S. amurensis . A: whole genitalia, lateral view. B: Terminalia, ventral view. C: Genital plate, ventral view. 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). Biology. The larvae feed on Fomes fomentarius [Japanese name: Tsuriganetake] and Laricifomes officinalis [Japanese name: Eburiko] ( Sohn 2007 ; Sakai 2013 ). FIGURE 7 .

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.
