Areas of endemism, defined by the congruence of the distribution of two or more taxa that are only found in that specific area, are considered an important input for biogeographic regionalization and determining priority areas for conservation. Herein we inferred the areas of endemism of Gerromorpha and their representation within the current protected areas system of Colombia. We analyzed 480 records of 69 species of semiaquatic bugs (Hemiptera - Gerromorpha) using the NDM/VNDM and three different grid sizes. We identified eight areas of endemism and 15 endemic species belonging to the genera Altavelia, Hydrometra, Oiovelia, Microvelia, Platygerris, Potamobates, Rhagovelia, Rheumatobates, Stridulivelia, Telmatometropsis and Veloidea. We identified five consensus areas. The endemism patterns of Gerromorpha from smaller units within the biogeographic provinces proposed by Morrone (Zootaxa 2014, 3782, 1-110). Rather, they form smaller units within provinces, similar to those found in vertebrates, suggesting the existence of biogeographic districts and therefore the need for a new classification. Only six of the 15 endemic species are protected under the current protected areas system. Defining Gerromorpha AEs constitutes a first step to infer the biogeographic history and the evolutionary processes that influence the distribution of semiaquatic bugs in Colombia and guide actions for their conservation.
特有分布区是由仅在特定区域发现的两个或更多分类单元分布的一致性所定义的，被认为是生物地理区域划分和确定保护优先区域的重要依据。在此，我们推断了水黾亚目昆虫的特有分布区及其在哥伦比亚现行保护区系统中的代表性。我们使用NDM/VNDM和三种不同的网格大小分析了69种半水生蝽（半翅目 - 水黾亚目）的480条记录。我们确定了8个特有分布区以及属于Altavelia、Hydrometra、Oiovelia、Microvelia、Platygerris、Potamobates、Rhagovelia、Rheumatobates、Stridulivelia、Telmatometropsis和Veloidea属的15个特有物种。我们确定了5个共识区域。水黾亚目的特有分布模式并非来自Morrone提出的生物地理省份内的较小单元（《动物分类学》2014年，3782卷，1 - 110页）。相反，它们在省份内形成了较小的单元，类似于在脊椎动物中发现的那些，这表明存在生物地理区，因此需要一个新的分类。在现行保护区系统下，15个特有物种中只有6个受到保护。定义水黾亚目的特有分布区是推断生物地理历史和影响哥伦比亚半水生蝽分布的进化过程并指导其保护行动的第一步。
