To date, no mayflies have been described from Cape Verde, an archipelago of volcanic islands in the Atlantic Ocean. Based on the material collected on two islands, Santo Antão and Santiago, two species of the genus Cloeon Leach, 1815 (Ephemeroptera: Baetidae) are described based on larvae and imagines. Cloeon morna sp. n., collected in Santo Antão, and C. sidadi sp. n., collected in Santiago, have 3-segmented maxillary palps and tapered labial palps of larvae. The new species can be distinguished from each other and from other West-African species of the genus mainly according to details of the lateral spines on larval abdominal segments and characteristic colourations of vitta and terga in female imagines and colours of male turbinate eyes. Affinities to the West African species of the genus are discussed.
迄今为止，尚未有关于佛得角（大西洋中的一个火山群岛）蜉蝣的描述。基于在圣安唐岛和圣地亚哥岛采集的材料，依据幼虫和成虫描述了1815年利奇所定的Cloeon属（蜉蝣目：短丝蜉科）的两个物种。在圣安唐岛采集到的Cloeon morna新种，以及在圣地亚哥岛采集到的C. sidadi新种，其幼虫具有3节的下颚须和渐细的唇须。这两个新物种彼此之间以及与该属其他西非物种的区分，主要依据幼虫腹部节段侧刺的细节、雌虫成虫纵带和背板的特征颜色以及雄虫陀螺形复眼的颜色。文中还讨论了与该属西非物种的亲缘关系。
