The genus Scaptodrosophila Duda part I: the brunnea species group from the Oriental Region, with morphological and molecular evidence (Diptera, Drosophilidae)

摘要

Seven new species of the Scaptodrosophilabrunnea species group are described from east Asia: S.maculatasp. n., S.melanogastersp. n., S.nigricostatasp. n., S.nigripectasp. n., S.obscuratasp. n., S.protenipenissp. n. and S.rhinasp. n. Three known species, S.parabrunnea (Tsacas & Chassagnard), S.pressobrunnea (Tsacas & Chassagnard) and S.scutellimargo (Duda) are redescribed. A key to all the examined species in the brunnea group is provided. Species delimitations have been improved by integrating the DNA sequences with morphological information. The intra- and interspecific pairwise p-distances (proportional distance) are summarized. Some nucleotide sites with fixed status in the alignment of the COI sequences (664 nucleotide sites in length) are used as ?￠????pure?￠???? molecular diagnostic characters to delineate species in the brunnea group.
