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.
德梅耶雷属（双翅目，果蝇科）已知包含30个已描述物种和近60个未描述物种，分为六个物种组。其中，由七个已知物种（两个东南亚物种和五个中国物种）组成的组因其对天南星科魔芋亚科宿主植物的专一性而显得独特。在本文中，描述了两个新物种，即焦氏德梅耶雷果蝇和高氏德梅耶雷果蝇，它们是该组的成员，标本分别采自中国云南天南星科魔芋属宿主物种滇魔芋（肖特）和疣柄魔芋（英格尔斯和克劳斯）的花序。与所有已知物种相比，这两个新物种不仅基于形态学，还基于DNA条形码（线粒体细胞色素c氧化酶亚基I基因的部分序列）数据进行界定。提供了该物种组所有九个物种的修订检索表。
