A new species of the subgenus Rhodobaetis Jacob, 2003, namely Baetis (Rhodobaetis) vadimi sp. nov., is described based on immature larvae from several localities in Georgia and Turkey. It is the ninth species of the subgenus for Transcaucasia, following six species formally recorded from Turkey and two endemic species described from the Central Caucasus. Larval characters are investigated and illustrated by means of scanning electron microscopy, and discussed in details. The differential diagnosis of this species is provided with regard to other representatives of the subgenus considering the feature set common for Rhodobaetis. The new species can be distinguished from its relatives (species which lack stout setae on the gills' margins), mainly by some characters of mouthparts (particularly labium), the shape and arrangement of stout setae and scales on the body surface, as well as the lack of subapical tiny setae on tarsal claw, and presence of numerous marginal spines and semilunar scale bases on the paraproct plate.
基于从格鲁吉亚和土耳其多个地点采集的未成熟幼虫，描述了红蜉属（Rhodobaetis Jacob，2003）的一个新物种，即瓦迪红蜉（Baetis (Rhodobaetis) vadimi sp. nov.）。这是外高加索地区该亚属的第九个物种，此前在土耳其正式记录有六个物种，在中高加索地区描述有两个特有物种。通过扫描电子显微镜对幼虫特征进行了研究和展示，并进行了详细讨论。考虑到红蜉属共有的特征集，对该物种与亚属的其他代表物种进行了鉴别诊断。该新物种可与其近缘种（鳃边缘无粗壮刚毛的物种）区分开来，主要依据一些口器特征（特别是下唇）、体表粗壮刚毛和鳞片的形状及排列，以及跗爪上缺乏亚顶端微小刚毛，并且在肛侧板上有许多边缘刺和半月形鳞片基部。
