Taxonomy and molecular phylogeny of the<i>Phortica hani</i>species complex (Diptera: Drosophilidae)

Abstract

A key to all the species of the hani complex is provided based on morphological data.In addition, a 'molecular' key to seven species of this complex was also elaborated based on DNA sequences of the mitochondrial ND2 and COI genes.The relationships amongst these seven species, and their relationships to the Phortica magna and Phortica variegata species complexes, are analysed based on the ND2 and COI sequence data.The results suggest that the P. hani complex is monophyletic; the P. magna and P. variegata complexes are closer to each other than either is to the P. hani complex, and both are closer to the P. hani complex than the Phortica foliiseta species complex or the Phortica varipes species group.
