Descriptions of two new species of the genus (Diptera, Drosophilidae) breeding on host plants in Yunnan, China.

The genus de Meijere (Diptera, Drosophilidae) is known to include 30 described and nearly 60 undescribed species classified into six species groups. Among these, the group of seven known species (two Southeast Asian and five Chinese) proved to be peculiar for its specificity on monsteroid (subfamily Monsteroideae, family Araceae) host plants. In this paper, two new species, Jiao & Gao, and Jiao & Gao, , are described as members of the group with specimens collected from inflorescences of the monsteroid host species (Roxb.) Schott and Engl. & Krause, respectively, in Yunnan, China. The two new species are delimitated, in comparison with all known species, based on not only morphological but also DNA barcode (partial sequence of the mitochondrial , i.e., cytochrome oxydase subunit I, gene) data. A revised key to all the nine species of the species group is provided.
