Morphology and DNA barcodes of two species of Bradysia Winnertz from China (Diptera, Sciaridae), with the description of Bradysia minorlobus Yang, Shi amp; Huang sp. n.

Two morphologically similar species of the fungicola species group of Bradysia Winnertz, 1867 were studied in China: Bradysia chenjinae Yang, Zhang Yang, 1993 and Bradysia minorlobus Yang, Shi Huang sp. n. The morphological species concepts were supported by the DNA barcodes of COI sequences. The genetic distances of 16 Bradysia fungicola group species were analyzed and a neighbor-joining tree was constructed. The morphological characters of both Chinese species were described and illustrated.
