The genus Mystrium is revised for the Malagasy region. Six species, Mystrium barrybressleri sp. n., Mystrium labyrinth sp. n., Mystrium eques sp. n., Mystrium mirror sp. n., Mystrium shadow sp. n., and Mystrium janovitzi sp. n. are described as new. Two existing names, Mystrium fallax Forel and Mystrium stadelmanni Forel, are synonymized with Mystrium voeltzkowi Forel and Mystrium mysticum Roger, respectively. All recognized species, including species outside of the Malagasy region, are assigned to one of the three newly proposed species groups. The associations between existing names and males are reexamined, and males of eight of the ten Malagasy species are described or redescribed. The taxonomic history of Mystrium highlights the importance of using unique identifiers when designating type specimens and the use of deposited vouchers in phylogenetic and ecological studies. Keys to species for workers, queens, and males are provided. Furthermore, a neotype for Mystrium mysticum is designated, as well as lectotypes for Mystrium camillae Emery, Mystrium rogeri Forel, Mystrium fallax Forel, Mystrium oberthueri Forel, Mystrium stadelmanni Forel, and Mystrium voeltzkowi Forel. Stigmatomma gingivale (Brown) is reassigned to Amblyopone as comb. rev. and Amblyopone awa Xu & Chu, Amblyopone kangba Xu & Chu, Amblyopone meiliana Xu & Chu, and Amblyopone zomae Xu & Chu are transferred to the genus Stigmatomma as comb. n.
对马达加斯加地区的密氏蚁属进行了修订。描述了6个新物种，即巴里布雷斯勒密氏蚁（Mystrium barrybressleri sp. n.）、迷宫密氏蚁（Mystrium labyrinth sp. n.）、骑士密氏蚁（Mystrium eques sp. n.）、镜面密氏蚁（Mystrium mirror sp. n.）、暗影密氏蚁（Mystrium shadow sp. n.）和雅诺维茨密氏蚁（Mystrium janovitzi sp. n.）。两个现有名称，即福尔氏伪密氏蚁（Mystrium fallax Forel）和施塔德曼氏密氏蚁（Mystrium stadelmanni Forel），分别被认定为福尔氏沃尔特氏密氏蚁（Mystrium voeltzkowi Forel）和罗杰氏神秘密氏蚁（Mystrium mysticum Roger）的同物异名。所有已确认的物种，包括马达加斯加地区以外的物种，都被归入新提出的三个物种组之一。重新审视了现有名称与雄性个体之间的关联，并对马达加斯加地区10个物种中的8个物种的雄性个体进行了描述或重新描述。密氏蚁属的分类历史突出了在指定模式标本时使用唯一标识符以及在系统发育和生态学研究中使用保存凭证的重要性。提供了工蚁、蚁后和雄蚁的物种检索表。此外，指定了神秘密氏蚁的新模式标本，以及卡米拉密氏蚁（Mystrium camillae Emery）、罗杰氏密氏蚁（Mystrium rogeri Forel）、福尔氏伪密氏蚁、奥伯图氏密氏蚁（Mystrium oberthueri Forel）、施塔德曼氏密氏蚁和沃尔特氏密氏蚁的选模标本。牙龈点刻蚁（Stigmatomma gingivale (Brown)）被重新划归钝猛蚁属（Amblyopone），新组合名为牙龈钝猛蚁（Amblyopone gingivale）；徐氏阿瓦钝猛蚁（Amblyopone awa Xu & Chu）、康巴钝猛蚁（Amblyopone kangba Xu & Chu）、梅里安钝猛蚁（Amblyopone meiliana Xu & Chu）和佐马钝猛蚁（Amblyopone zomae Xu & Chu）被转移到点刻蚁属（Stigmatomma），新组合名为阿瓦点刻蚁（Stigmatomma awa）、康巴点刻蚁（Stigmatomma kangba）、梅里安点刻蚁（Stigmatomma meiliana）和佐马点刻蚁（Stigmatomma zomae）。
