Description
Summary:A redescription of Eurycercus (Teretifrons) glacialis Lilljeborg, 1901 is given, based solely on type material from Bering Island, Komandorski Islands (= Commander Islands), east of Kamchatka Peninsula, USSR. Eurycercus nigracanthus n.sp. is described from Newfoundland, and represents the most southerly known taxon in the subgenus Teretifrons. Although the subgenus is considered to be Holarctic in distribution, it is now seen that the range of E. glacialis is more restricted; in particular, at least one new species (and probably more) in the subgenus exists in North America.
