A new species of Docosia Winnertz from Central Europe with DNA barcoding based on four gene markers (Diptera Mycetophilidae)

摘要

A new species of Docosia Winnertz, Docosia dentata >sp. n., is described and illustrated, based on a single male specimen collected in Muránska planina National Park in Central Slovakia. DNA sequences (COI, COII, CytB, and ITS2) are included and compared for 13 species of Docosia. There was found only little congruence between the molecular results and previous scarce data about interspecific relationships based on morphology. The COI and CytB gene markers showed the highest interspecific gene distances while ITS2 showed the lowest ones. An updated key to the 23 Central European species of Docosia is also presented.
