The poorly known Ceriagrion mourae is redescribed based on the first material from Zambia and compared with the similar C. banditum, C. junceum and C. suave. Molecular data place C. mourae as a sister taxon to the clade (C. bakeri (C. banditum, C. junceum)). Genetic distances between the above-mentioned species are similar at c.7–9% (K2P). Analysis of all published Ceriagrion COI sequences revealed a barcoding gap (c.2–6.5%) in the pairwise distance distribution and grouped African sequences according to the known species, except C. suave and C. glabrum. C. mourae was only found at a pool on a temporary stream, which differed from others in the study area by its combination of vegetation and shading. The Zambian locality and two earlier known sites in Mozambique and Tanzania are scattered across the plains and low hills of eastern and southern central Africa.

重新描述 Ceriagrion mourae 并说明其在 Ceriagrion 属（Odonata：Coenagrionidae）中的位置

鲜为人知的 Ceriagrion mourae 根据来自赞比亚的第一种材料重新描述，并与类似的 C. banditum、C. junceum 和 C. suave 进行了比较。分子数据将 C. mourae 作为进化枝 (C. bakeri (C. banditum, C. junceum)) 的姐妹分类群。上述物种之间的遗传距离相似，约为 c.7-9% (K2P)。对所有已发表的 Ceriagrion COI 序列的分析揭示了成对距离分布中的条形码差距 (c.2-6.5%)，并根据已知物种对非洲序列进行了分组，除了 C. suave 和 C. glabrum。C. mourae 仅在临时溪流的水池中发现，其植被和阴影的组合与研究区的其他人不同。
