Hypopygium ( Figs 3–10 ). Tergite IX with “anal point” which like small rounded protuberance, and with 29–42 setae, 12–20 μm long; laterosternite IX with 15–20 setae (from one side), 44–48 μm long. Transverse sternapodeme high, almost trapezoidal, 128–132 μm long of specimens from South Korea, 92 μm long of specimen from South Sakhalin, and 148–152

μm wide in basal part, 88–100 μm wide in subapical part, with rounded apex ( Figs 4–5 ).

Gonocoxite 308–310μm long. Basal lobe of gonocoxite is various shapes and depends on its position; in the inner half with microtrichia, along the outer margin with short setae ( Figs 3 ,

6–7, 10); inferior volsella as in Figs 3 , 10 , covered by setae 40–60 μm long. Gonostylus 156

μm long, scoop-shaped; inner lobe along the margin with 5–9 megasetae 12–16 μm long and one subterminal tooth; outer lobe widely triangular, inner margin of which with strong setae

20–24 μm long, outer half with thinner and longer setae 56–72 μm long ( Figs 3 , 8–10 ). HR

1.97.

REMARKS. Additional material from South Korea allowed a more detailed study of the internal structure of the male hypopygium, namely transverse sternapodeme, which in complex with aedeagal lobe, basal lobe of gonocoxite and inferior volsella is typical for Boreoheptagyiini . Males from both populations are close related by all features but specimens from

South Korea have more a long transverse sternapodeme (128–132 μm) than specimen from

South Sakhalin (92 μm).

DISTRIBUTION. East Palaearctic continental-insularis species known from Sakhalin

Island and Primorye Territory in Russia and from South Korea.
