A new subgenus, Reinertia Somboon, Namgay & Harbach, of the genus Aedes Meigen and its type species, Ae. suffusus Edwards, are described from specimens reared from larvae and pupae found in a tree hole in Bhutan. The scutum of the adults is mostly covered with narrow pale falcate scales. The proboscis, maxillary palpus, tibiae, and tarsi are dark-scaled. The gonocoxite of the male genitalia bears a unique setose basomesal sclerite. The larva closely resembles larvae of the subgenus Downsiomyia Vargus in having setae 4-6-C with numerous branches and inserted more or less on level with seta 7-C, abdominal seta 12-I is present and the comb is composed of 6-10 spine-like scales arranged in an irregular row. Surprisingly, Reinertia shares features of the adult habitus, male genitalia, and larva with the Palearctic subgenus Dahliana Reinert, Harbach & Kitching. However, in phylogenetic analyses of the mitochondrial COI gene of species representing 38 subgenera of Aedes and six other genera of the tribe Aedini Neveu-Lemaire, Reinertia was not associated with Dahliana or Downsiomyia. In both maximum likelihood and Bayesian analyses of the data, Ae. suffusus was recovered as the weakly supported sister of a clade composed of five species of the subgenus Protomacleaya Theobald. In the absence of strong support, and because Protomacleaya is an unnatural group of species that resemble each other phenetically by virtue of what they lack, Ae. suffusus cannot be placed in the subgenus Protomacleaya. Thus, the morphological and molecular data attest the uniqueness of Ae. suffusus and its recognition as a monobasic subgeneric lineage.
一个新的亚属，雷内尔蒂亚，宋博恩，南盖伊和哈巴赫，由伊蚊属迈根和它的模式种，伊蚊。suffusus 爱德华兹，是从在不丹树洞发现的幼虫和蛹中饲养的标本中描述的。成虫的盾片大部分被狭窄的淡色镰刀形鳞片覆盖。喙、触须、胫骨和跗节都是深色鳞片。雄性生殖器的肛节带有独特的具刚毛的basomesal 硬化片。幼虫与 Downsiomyia Vargus 亚属的幼虫非常相似，具有带许多分支的 4-6-C 刚毛，或多或少插入与 7-C 刚毛平齐，腹部 12-I 刚毛存在，梳由 6-10 个排列不规则行的刺状鳞片组成。令人惊讶的是，雷内尔蒂亚在成虫习性、雄性生殖器和幼虫方面与古北界的 Dahliana Reinert、Harbach 和 Kitching 亚属具有相似特征。然而，在代表伊蚊族 38 个亚属和其他 6 个属的物种的线粒体 COI 基因的系统发育分析中，雷内尔蒂亚与 Dahliana 或 Downsiomyia 没有关联。在最大似然和贝叶斯分析中，伊蚊。suffusus 被恢复为由 5 种 Protomacleaya Theobald 亚属组成的分支的弱支持姐妹种。在缺乏强烈支持的情况下，并且由于 Protomacleaya 是一个不自然的物种群，它们在形态上彼此相似，因为它们缺乏什么，伊蚊。suffusus 不能被放置在 Protomacleaya 亚属中。因此，形态和分子数据证明了伊蚊。suffusus 的独特性及其作为单系亚属谱系的识别。
