For the recently established genus Madagopsina (Diopsidae, stalk-eyed flies), Madagopsina makayensis Feijen, Feijen & Feijen, sp. nov. is described from Madagascar. A concise catalogue is given for the genus and an identification key is presented for its six species. The differential character states are listed for the two species groups of the genus: the Madagopsina apollo species group and the Madagopsina apographica species group. The intrageneric relations are discussed based on morphology, geometric morphometrics analysis of wing shape, and allometric data for eye span against body length. Each of these three procedures places the new species in the M. apollo species group with Madagopsina parvapollina as its closest relative. New records are presented for M. apographica and M. parvapollina.

对 Madagopsina Feijen、Feijen 和 Feijen（双翅目、Diopsidae）的回顾，描述了一个新物种、物种的关键，以及对属内关系的讨论

对于最近建立的 Madagopsina 属（Diopsidae，茎眼蝇）， Madagopsina makayensis Feijen，Feijen 和 Feijen，sp。十一月 描述来自马达加斯加。给出了该属的简明目录，并给出了其六个物种的识别码。列出了该属的两个物种组的差异特征状态：Madagopsina apollo 物种组和 Madagopsina apographica 物种组。基于形态学、机翼形状的几何形态计量学分析和眼跨与体长的异速生长数据讨论属内关系。这三个程序中的每一个都将新物种置于 M. apollo 物种组中，并将 Madagopsina parvapollina 作为其最近的亲戚。为 M. apographica 和 M. parvapollina 提供了新记录。
