Phylogeny of Drosophilinae (Diptera: Drosophilidae), with comments on combined analysis and character support.
Drosophilidae (Diptera) is a diverse, cosmopolitan family of flies. Here, we present a combined analysis phylogeny of Drosophilinae, one of the two subfamilies of Drosophilidae, based on data from six different data partitions, including both molecular and morphological characters. Although our data show support for the monophyly of the Hawaiian Drosophilidae, and the subgenus Sophophora, neither the genus Drosophila nor the subgenus Drosophila is monophyletic. Partitioned Bremer support (PBS) indicates that morphological data taken from Grimaldi's monograph (Grimaldi, 1990a), as well as sequences from the mitochondrial (mt) 16S rDNA and the nuclear Adh gene, lend much support to our tree's topology. This is particularly interesting in the case of Grimaldi's data, since his published hypothesis conflicts with ours in significant ways. Our combined analysis cladogram phylogeny reflects the catch-all designation that the name Drosophila has become, in that the cladogram does not support the monophyly of either the genus or subgenus Drosophila.
