tlooto Summary

Four times the 60 + 5 species of Dacnusini + Dapsilarthra-group species now recorded from Norway occur in the British Isles strongly suggesting that there are many more species yet to be discovered.

Abstract

Dacnusini and Dapsilartha Förster, 1862 genus-group wasps (Hymenoptera, Braconidae, Alysiinae) attack phytophagous Diptera, especially leaf miners. The group has been little studied in Norway and a critical review of the literature finds evidence for only 13 + 2 (Dacnusini + Dapsilarthragroup) species recorded in the country. This includes three species of Coelinidea Viereck, 1913 whose identities cannot be confirmed at present in the absence of a 20th or 21st century revision. DNA barcode sequences are now available in the Barcode of Life Database (BOLD) for 1155 specimens collected in Norway. Based on genetic and morphological study of these wasps a further 47 + 3 species are added to the Norwegian list. Dacnusa nipponica Takada, 1977 is noted from Europe for the first time and a third specimen of Coloneurella lomnickii Niezabitowski, 1910 is recorded (the sequence of which has revealed the presence of the genus Coloneurella van Achterberg, 1976 in North America). Wasps in a further 23 sequence clusters, where it has not been possible to assign names, are discussed. These include several known undescribed species, likely new species to science, and wasps where further research is needed to establish their identity (or in a few cases of singletons to exclude sequencing or other errors). One new synonym is established: Bracon pygmeator Zetterstedt, 1838 syn. n. = Synelix semirugosa Haliday, 1839. Four times the 60 + 5 species of Dacnusini + Dapsilarthra-group species now recorded from Norway occur in the British Isles strongly suggesting that there are many more species yet to be discovered.
