ABSTRACT We describe and illustrate Inbiomyia azevedoi, sp. nov., the first species of Inbiomyiidae known from the Atlantic Forest in southeastern Brazil. SEM photos show that the bifurcated labella have on their ventral face rows of scalelike rasping teeth that may be used to graze on green algae, as the gut content of some specimens suggest. A reanalysis of the phylogeny of the genus using Australimyza mcalpineorum as designated outgroup and including I. azevedoi shows that all four groups of species previously proposed for the genus are monophyletic if I. anodonta is removed from the scoliostylus group. Inbiomyia anodonta and I. azevedoi are here transferred to the anemosyris group. In our results with implied weight, I. exul is sister to a clade including all other species of the genus, while the scoliostylus group appears as sister to the clade (mcalpineourum group + anemosyris group).

来自巴西大西洋森林的第一个 Inbiomyia 种（双翅目：Inbiomyiidae）

摘要 我们描述和说明 Inbiomyia azevedoi, sp。11 月，巴西东南部大西洋森林中已知的第一个 Inbiomyiidae 物种。SEM 照片显示，分叉的标签在它们的腹面有一排鳞片状的锉齿，可以用来吃绿藻，正如一些标本的肠道内容物所表明的那样。使用 Australimyza mcalpineorum 作为指定的外群并包括 I. azevedoi 对该属的系统发育进行重新分析表明，如果 I. anodonta 从 scoliostylus 组中移除，则先前为该属提出的所有四组物种都是单系的。Inbiomyia anodonta 和 I. azevedoi 在这里转移到 anemosyris 组。在我们隐含重量的结果中，I. exul 是包括该属所有其他物种的进化枝的姐妹，
