Survey of the genus Stegana Meigen (Diptera, Drosophilidae) from Taiwan, with DNA barcodes and descriptions of three new species.

The article presents a study which focuses on the survey of the three new species of the genus Stegana Meigen or diptera from Taiwan. The study uses the sequencing of the DNA barcoding fragments of the mitochondrial cytochrome oxidase I (COI) gene for the delineation of the species. Results show that two most widely distributed species among the 23 recorded species are ranging across two zoogeographic regions.
