TL: [SE Russia, Primorye Region] “Ussuri-Gebiet, Sedunka [=Sedanka] bei Wladiwostok ... und Anutschino“. Types: male and female, not found.
Diagnosis. Forewings are reddish or pinkish brown, medial fasciae are dark grey, bordered interiorly by whitish scales—narrow in males and rather broad in females. Hind wings are darker in males, lighter in females, sometimes with a weak transversal grayish band.
In the male genitalia (fig. 21), the shape of the valva is diagnostic, as its apical part is roughly trapezoid shaped to irregularly rectangular, with an obtuse outer margin; juxta bears long lateral lobes.
In the female genitalia, the antevaginal plate is strong and broad, with its caudal margin cut; postvaginal plate with triangular caudal cut; distinct medio-transversal keel and numerous lateral wrinkles; ostium broad, membranous; antrum and ductus bursae reduced; corpus bursae short, bag-shaped, membranous.
This species is geographically isolated from other congeners. It can be distinguished by the forewings being rather unicolorous in males, with reduced whitish fasciae, well developed epiphysis and genitalic characters such as the characteristic valva shape.
Bionomics. Univoltine, flight period from late August to late October, peaking in the second half of September. The adults are very local and fly in the first half of the night in humid oak forests or rarely in mixed conifer-oak forests. Tschistjakov (1995) treated it as a rare species restricted to some localities within a subzone of mixed coniferous-broadleaved forests with a predominance of Abies holophila . Quercus mongoliсa is a hostplant in Russia. The pupae aestivate and the moths hatch after the first autumnal ground frosts. Eggs spherical, white with spotted reddish pattern; micropylar zone pointed with black. Larva flattened dorso-ventrally, with thoracic lateral lappets; ground colour light yellowish grey with small black spots and marbled pattern especially rich laterally; second and third thoracic segments with velvet-black transversal bands; abdominal segments with a broad yellow band, A2 with 4 small black horns and A11 with a single yellowish brown hook; blackish and yellowish setae, longer laterally; length of mature caterpillar about 40 mm ( Graeser, 1888).
Distribution. Russian Far East (from Khabarovsk ( Dubatolov & Dolgikh, 2007) and NE Primorye: Maximovka ( Tschistjakov, 1995) to Southern Primorye Region), Korea (Gwangleung and Mt. Jugeum-san—Park et al., 1999: 138 as Arguda vinata (Moore, 1865) , also from Hwanghae: Sinpyong, see below), NE China (Heilongjiang, Jilin, Henan—Liu & Wu, 2006).
Taxonomic note. The holotype and allotype of the species were not found in any European museum and are probably lost. They were illustrated in the original description so authenticity of the species is certain. No information on the deposition of Karl Grünberg’s collection is known, however, topotypical specimens collected later are widely represented in different European collections.
Material examined. About 70 specimens from different locations of Far East Russia ( ZISP, MWM, BMNH, ZFMK, ZHUB, etc).
