Abstract

Eight new species of the Scaptodrosophila coracina species group are described from China: S. fuscilimba sp. n., S. fusciventricula sp. n., S. helvpecta sp. n., S. longispinata sp. n., S. nigrolimbata sp. n., S. trivittata sp. n., S. ventriobscurata sp. n., and S. zebrina sp. n. One known species S. coracina (Kikkawa & Peng) is redescribed. A key to all the examined species in the coracina group is provided. Species delimitations have been improved by integrating the DNA sequences with morphological information. The intra- and interspecific pairwise p-distances (proportional distance) are summarized. Some nucleotide sites with fixed status in the alignment of the COI sequences (662 nucleotide sites in length) are used as “pure” molecular diagnostic characters to delineate species in the coracina group.
