The tribe Xylenini Guenée, is especially rich in the Himalayan region with the highest diversity occurring during the late fall and winter. Exploration of this fauna has a rich history but became especially intensive during recent decades resulting in many new descriptions. Milestones in this vast territorial study by country include Pakistan (Ronkay Ronkay 1999), India (Hacker 1992), Nepal (Hreblay Ronkay 1998, Benedek et al. 2013), Taiwan (Hreblay Ronkay 1997; 2000, Ronkay Ronkay 2000) Thailand, Vietnam (Hreblay et al. 1999) and China (Ronkay et al. 2010, Benedek et al. 2012; 2013). To this list we now add the mountainous areas of Myanmar which have only recently become accessible. During a late fall collecting trip to Western Myanmar, three specimens of a strange looking noctuid species externally somewhat similar to the Western Himalayan Mniotype leucocyma (Hampson, 1907) were collected. After examination of its male and female genitalia, this species was proven to be new to science. Moreover, the male genitalia of the new species show a surprisingly unusual complex of features, some of which, together with the female genitalia, are characteristic and decisively significant to the subtribe Xylenina. The male and female genitalia of this species are most similar to those of the genera Eupsilia Hübner and Owadaglaea Hacker Ronkay, however, these genitalia have certain autapomorphic characters which clearly justify separation on generic level. The description of the new genus and species is given below with a comparison to the related Eupsilia and Owadaglaea, several other related genera (Lithophane Hübner, Conistra Hübner and Xylena Ochsenheimer) and the externally similar M. leucocyma as well.
希夜蛾族（Xylenini Guenée）在喜马拉雅地区尤为丰富，在深秋和冬季多样性最高。对该动物群的探索历史悠久，但近几十年来变得尤为密集，导致了许多新的描述。按国家划分，这一广阔区域研究的里程碑包括巴基斯坦（龙凯·龙凯，1999年）、印度（哈克，1992年）、尼泊尔（赫布莱·龙凯，1998年；贝内德克等人，2013年）、台湾（赫布莱·龙凯，1997年；2000年；龙凯·龙凯，2000年）、泰国、越南（赫布莱等人，1999年）以及中国（龙凯等人，2010年；贝内德克等人，2012年；2013年）。现在我们在这份名单中增加了缅甸的山区，这些地区直到最近才得以进入。在一次深秋前往缅甸西部的采集之旅中，采集到了三只外观奇特的夜蛾科物种标本，它们在外部与西喜马拉雅地区的白点希夜蛾（Mniotype leucocyma，汉普森，1907年）有些相似。在检查了其雌雄生殖器后，证明该物种是科学上新发现的。此外，新物种的雄性生殖器呈现出令人惊讶的异常复杂特征，其中一些特征，连同雌性生殖器的特征，对于希夜蛾亚族来说是具有特征性且具有决定性意义的。该物种的雌雄生殖器与优夜蛾属（Eupsilia Hübner）和奥氏夜蛾属（Owadaglaea Hacker Ronkay）最为相似，然而，这些生殖器具有某些自近裔性状，这显然足以证明在属级水平上进行划分是合理的。下面给出新属和新物种的描述，并与相关的优夜蛾属、奥氏夜蛾属、其他几个相关属（亮夜蛾属（Lithophane Hübner）、锥夜蛾属（Conistra Hübner）和希夜蛾属（Xylena Ochsenheimer））以及外部相似的白点希夜蛾进行比较。
