Liaghinella Wygodzinsky, 1966 (Hemiptera: Heteroptera: Reduviidae: Emesinae: Metapterini), is an endemic Neotropical genus with two described species, one from Jamaica and one from Colombia. In this paper we describe two additional new species from the high Andes in Colombia, Liaghinella heldamariae sp. nov from Monserrate and Villa de Leyva, and L. tuberculata sp. nov. from Chicaque Natural Park, both in the Eastern Cordillera. The new species were collected very close to the type locality of the previously known Colombian species, L. andina Forero, 2007. These two new species differ from L. andina by having both a pair of conspicuous tubercles on the posterior margin of the pronotum, and by the structure of the male and female genitalia. Species diagnosis and descriptions, digital macrophotographies, and a key to separate the species of Liaghinella are presented. A discussion on the small range distributions exhibited by the high Andean species of Liaghinella is provided.
利亚金蝽属（Liaghinella）由维戈津斯基（Wygodzinsky）于1966年建立（半翅目：异翅亚目：猎蝽科：埃梅蝽亚科：后蝽族），是新热带界的特有属，已描述的有两个物种，一个来自牙买加，另一个来自哥伦比亚。在本文中，我们描述了来自哥伦比亚安第斯山脉高处的另外两个新物种，来自蒙塞拉特和莱瓦镇的赫尔德玛丽亚利亚金蝽（Liaghinella heldamariae）新种，以及来自东科迪勒拉山脉奇卡克自然公园的瘤状利亚金蝽（L. tuberculata）新种。这两个新物种是在非常靠近先前已知的哥伦比亚物种——2007年的安第斯利亚金蝽（L. andina Forero）的模式产地采集到的。这两个新物种与安第斯利亚金蝽的区别在于，它们在前胸背板后缘都有一对明显的瘤，以及雌雄生殖器的结构。文中给出了物种诊断与描述、数码微距照片，以及区分利亚金蝽属各物种的检索表。还对利亚金蝽属安第斯山脉高处物种所呈现的小范围分布进行了讨论。
