Two new European species of Delia Robineau-Desvoidy (Diptera: Anthomyiidae) with a bipartite male sternite III.

Research output: Contribution to journalArticle


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.
