Six new species of Macrostomus Wiedemann are described, namely M. acreanus sp. nov. from Brazil (Acre state), M. amazonensis sp. nov. from Guyana and Brazil (Roraima, Amazonas, Pará, Rondônia, and Mato Grosso states), M. albicaudatus sp. nov. from Brazil (Roraima, Amazonas, and Pará states), M. paraiba sp. nov. from Brazil (Paraíba state), M. trombetensis sp. nov. from Brazil (Pará state) and M. xavieri sp. nov. from Guyana and Brazil (Amazonas state). The six species are all treated in the M. amazonensis species-group, which is defined on the basis of one pair of ocellar setae and no supra-alar postsutural setae in combination with characters of the male and female terminalia. A key to the included species is presented and the geographical distributions of the species are mapped.
描述了威德曼巨口蝇属（Macrostomus Wiedemann）的六个新物种，即来自巴西（阿克里州）的阿克里巨口蝇（Macrostomus acreanus sp. nov.）、来自圭亚那和巴西（罗赖马州、亚马逊州、帕拉州、朗多尼亚州和马托格罗索州）的亚马逊巨口蝇（Macrostomus amazonensis sp. nov.）、来自巴西（罗赖马州、亚马逊州和帕拉州）的白尾巨口蝇（Macrostomus albicaudatus sp. nov.）、来自巴西（帕拉伊巴州）的帕拉伊巴巨口蝇（Macrostomus paraiba sp. nov.）、来自巴西（帕拉州）的特龙贝塔斯巨口蝇（Macrostomus trombetensis sp. nov.）以及来自圭亚那和巴西（亚马逊州）的哈维里巨口蝇（Macrostomus xavieri sp. nov.）。这六个物种均属于亚马逊巨口蝇物种组，该物种组是根据一对单眼刚毛、无翅上缝后鬃以及雄雌外生殖器特征来定义的。给出了所包含物种的检索表，并绘制了这些物种的地理分布图。
