Abstract
The Helina obtusipennis species-group is erected for nine species of Helina in the Palaearctic and Oriental regions, namely H. atlantica (Tiensuu), H. ciliatocosta (Zetterstedt), H. eurymetopa Emden, H. macrocera Hennig, H. mandschurica Hennig, H. medogensis sp. nov., H. obtusipennis (Fallén), H. setigera (Pokorny), and H. spinicosta ( Zetterstedt). These species are Palaearctic in distribution except for H. eurymetopa Emden and H. medogensis, which are known from the Oriental Region. Members of this group can be easily differentiated from those of other Helina species-groups by their broad frons in both sexes with one or two pairs of upper orbital setae. A key to the males of the H. obtusipennis species-group is given.References
