Molecular phylogeny of Chrysomya albiceps and C-rufifacies (Diptera : Calliphoridae)

Mitochondrial DNA was used to infer the phylogeny and genetic divergences o f Chrysomya albiceps (Wiedemann) and C. rufifacies (Maquart) specimens from widely separated localities in the Old and New World. Analyses based on a 2.3-kb region including the genes for cytochrome oxidase subunits I and II indicated that the 2 species were separate monophyletic lineages that have been separated for >1 million years. Analysis of DNA, in the form of either sequence or restriction fragment-length polymorphism (RFLP) data, will per mit the identification of problematic specimens.
