The genus Mesamphiagrion Kennedy, 1920, occurs in the Pantepui region and northern Andes in South America and is most speciose in Colombia where the genus is less known. In this work, we record 10 species of Mesamphiagrion from Colombia, including four new species (Mesamphiagrion gaudiimontanum Bota-Sierra sp. nov., M nataliae Bota-Sierra sp. nov., M. rosseri Bota-Sierra sp. nov., and M. santainense Bota-Sierra sp. nov.). We also redescribe the male of M risi (De Marmels 1997) and describe the females of M. risi, M. ovigerum (Calvert, 1909), and M occultum (Ris, 1918), which were previously unknown. Descriptions, photographs, illustrations, distribution maps, natural history notes, and a diag nostic key for males and females of Mesamphiagrion from Colombia are provided.
梅萨细蟌属（Mesamphiagrion Kennedy，1920）分布于南美洲的潘塔纳尔地区和安第斯山脉北部，在哥伦比亚种类最为丰富，而该属在哥伦比亚却鲜为人知。在这项研究中，我们记录了来自哥伦比亚的10种梅萨细蟌，包括4个新物种（高迪山梅萨细蟌Mesamphiagrion gaudiimontanum Bota-Sierra新种、娜塔莉亚梅萨细蟌M nataliae Bota-Sierra新种、罗瑟里梅萨细蟌M. rosseri Bota-Sierra新种和圣塔伊内斯梅萨细蟌M. santainense Bota-Sierra新种）。我们还重新描述了里西梅萨细蟌（M risi，De Marmels 1997）的雄性，并描述了此前未知的里西梅萨细蟌、卵形梅萨细蟌（M. ovigerum，Calvert，1909）和隐匿梅萨细蟌（M occultum，Ris，1918）的雌性。文中提供了来自哥伦比亚的梅萨细蟌的描述、照片、插图、分布图、自然史记录以及雄性和雌性的诊断检索表。
