Abstract

Glabellula arctica (Zett.) is recorded from three Swedish provinces as an ant guest, living in the nests of four Formica species. Some details of the behaviour of the adult and the larva are described as well as the morphology of the last larval instar, the pupa and the malc and fcmale abdomina. The systematic position of the species is discussed.

Abstract

Lectotypes are designated for Cordylura dentimana Zetterstedt, 1838, Cordylura fulvipes Zetterstedt, 1838, Cosmetopus bergrothi Becker, 1900, and Cosmetopus simplicipes Becker, 1900. C. fulvipes Zett. is found to be a synonym of C. dentimana Zett. (n. syn.). The opinion that C. bergrothi is a synonym of Cosmetopus longus (Walker, 1849) and that C. simplicipes Beck. should be treated in a separate genus, Pleurochaetella Vockeroth, is confirmed. Cosmetopus ringdahli n. sp. is described and figured on material from Sweden and Finland. Distinctive characters of the other species are discussed and partly figured.

Abstract

Hybomitra auripila (Meig.) and H. aterrima (Meig.) have been recorded from Scandinavia, and Tabanus aethiops Ljungh, T. lugubris Zett. and T. nigerrimus Zett. have been treated as synonyms of H. aterrima (Meig.). The present study shows that only H. auripila (Meig.) has been found in Scandinavia and that T. aethiops Ljung, T. lugubris Zett. and T. nigerrimus Zett. are synonyms of H. auripila (Meig.). Lectotypes have been designated for these three names.
