| diversification of sympatric sapromyza (diptera: lauxaniidae) from madeira: six morphological species but only four mtdna lineages. | a series of recent studies on speciation of insects within the canary islands have indicated considerable within-island diversification, similar to that described in the hawaiian islands. little work has yet been carried out on the neighboring madeiran archipelago, which is also volcanic. this study examines relationships among all known lauxaniid flies of the genus sapromyza from madeira (including six newly described morphological species) based on mitochondrial gene trees constructed from cyt ... | 2003 | 12742747 |
