Sammanfattning (abstract):
The chats and flycatchers (Muscicapidae) represent an assemblage of 275 species in 48 genera. Defining
natural groups within this assemblage has been challenging because of its high diversity and a paucity of
phylogenetically informative morphological characters. We assessed the phylogenetic relationships of
124 species and 34 genera of Muscicapidae, and 20 species of Turdidae, using molecular sequence data
from one mitochondrial gene and three nuclear loci, in total 3240 bp. Bayesian and maximum likelihood
analyses yielded a well-resolved tree in which nearly all basal nodes were strongly supported. The traditionally
defined Muscicapidae, Muscicapinae and Saxicolinae were paraphyletic. Four major clades are
recognized in Muscicapidae: Muscicapinae, Niltavinae (new family-group name), Erithacinae and Saxicolinae.
Interesting relationships recovered by this analysis include: (i) a clade comprising the ‘blue’ flycatcher
genera Niltava, Cyornis, Cyanoptila and Eumyias and some species of Rhinomyias; (ii) the position
of Erithacus rubecula in a clade of otherwise exclusively African species; (iii) a close relationship between
the shortwing Heinrichia calligyna and the flycatcher Rhinomyias insignis; (iv) a sister-relationship
between forktails Enicurus and whistling thrushes Myophonus; and (v) a sister relationship of Ficedula
and the ‘chats’ Monticola, Phoenicurus, Saxicola and Oenanthe. A high number of traditionally defined genera
was found to be paraphyletic or polyphyletic.
