( Figs 2 , 7 , 12 )

Phalaena arcuella Clerck, 1759 : pl. 10, fig. 8. TL: Europe.

Phalaena arcuana Linnaeus, 1761: 344 .

Phalaena lambergiana Scopoli, 1763: 234 .

Diagnosis. This species closely resembles four other species: O. captiosana (Falkovitsh) , O. oculata Kim, Byun & Bae , O. subtilana (Falkovitsh) and O. palbongensis sp. nov. Kim & Bae. However, it can be distinguished by its male genitalia, which feature two groups of cornuti.

Material examined. [ Germany] 1 ♂, Hannover Misb Holz, 16 VI 1907, genitalia slide No. MGCL-1174104 ; 1 ♀, Bohemia: Bodenbach. Leg. Zimmermann, 20 VII 1938, genitalia slide No. MGCL-1174105.

Distribution. Austria, Bulgaria, Czech Republic, Germany, Romania, Slovenia (Andreas et al. 2011).

Host plant. Larvae feed on dead Betula leaves ( Heckford 2011).

Remarks. This species was reported in Korea by Walsingham (1900), but it was corrected later as a misidentification of O. captiosana by Park (1983).
