1 specimen (NMW). Remarks -In the original description Eusphaierum sibiricum is compared with E. rectangulum (FAUVEL), a European species, and E. transcaucasicum from the Caucasus. However, the holotype of sibiricum is very similar to nigriventre (MOTSCHULSKY), from which it is distinguished by slenderer general shape (Figs 3536), and mainly by the aedeagus with subparallel-sided median lobe and internal sac with few thorns not much evident, and not gathered in groups (Figs 6-7), like in nigriventre. The other specimens that I have referred to as sibiricum differ from the type in narrower median lobe (Fig. 5) (this character can be an artefact of the killing procedure) and in more or less darker metasternum. E. sibiricum is perhaps a polytypical species. Eusphaierum reitteri (BERNHAUER, 1935) (Figs 10-12,37-38) Anthobium reitteri BERNHAUER, 1935: 39. Eusphaierum reitteri: TlCHOMlROVA 1973: 137.

Chitaizki-Strema, 1 male (without aedeagus, tentatively determined) (FMNHC); Korea, Mt. Pektusan Explosion Lake, 20002500 m, 18.VII.1977, No. 369, netting in grasses, leg.

SZÉL, 2 males (HNHM); Korea, Ryanggang Prov., Konchang, 800 m, No. 1368, 30.VI.1988, leg. O. MERKL et GY. SZÉL, 3 males and 2 females (HNHM, Z); Korea, Prov. Kanwon, Kum-gang san, Man-mul san 30.V1970, Hung. Zool. Exp. I in Korea, No. 66, leg. Dr. S. MAHUNKA et Dr. H. STEINMANN, 14 males (HNHM, Z). Remarks - I was unable to find the type locality ("Sotka Gora") of this species in the atlases. Dr. V. GUSAROV from Leningrad informed me that "perhaps they mean some hills a hundred metres above sea level, which on our maps may be marked as 100 m a.s.l. (that is, "sto", "sotnya", "sotka" in Russian). In East Siberia there can be many such hills, besides this name "Sotka" sounds like some local name". The specimens form Korea I examined differ from the type in having duller pronotum on the average, and in having larger thorns in the internal sac of the aedeagus. In the original description E. reitteri is compared with E. lapponicum (MANNERHEIM), and differs in the following characters: much smaller, flatter, and mainly, with much stronger, sparser and
