Description
Summary:Two species within the Delia cardui species group were known to have males with the abdominal sternite III bipartite or very deeply incised, viz., D. bipartita Suwa from Japan and China and D. polaris Griffiths from extreme northern and high-altitude sites in North America. Two new species with this extraordinary character are described from northern Europe: D. rimiventris sp. nov. from southern Norway (Vest-Agder; Oppland) and southern Finland (Regio aboensis; Karelia australis) and D. bipartitoides sp. nov. from northern Sweden (Norrbotten). Further records of the latter species from Mongolia and Russia (Yakutia) are given. A discussion and redefinition of the Delia cardui species group and a key to male Delia with a divided sternite III are given.
