A new species of the extinct bee genus Ctenoplectrella Cockerell (Megachilinae: Ctenoplectrellini) is described and figured from two females preserved in middle Eocene (Lutetian) Baltic amber. Ctenoplectrella phaetonsp. n. is distinguished from its congeners on the basis of its body proportions, integumental sculpturing, wing venation, and pubescence, and is one of the more distinctive members of the genus. A revised key to the species of Ctenoplectrella is provided.

从保存在始新世中期（路特提亚期）波罗的海琥珀中的两只雌性个体描述并图示了已灭绝的蜜蜂属Ctenoplectrella Cockerell（切叶蜂亚科：Ctenoplectrellini）的一个新物种。新物种Ctenoplectrella phaetonsp. n. 根据其身体比例、体表雕刻、翅脉和毛被与同属其他物种相区分，是该属中较为独特的成员之一。还提供了一份修订后的Ctenoplectrella属物种检索表。
