(Wiedemann, 1821) (Diptera: Tabanidae) is a hematophagous insect of veterinary and medical importance and is the predominant spp. in Thailand. It is a potential mechanical vector of , which causes surra in domestic and wild animals. Wing geometric morphometrics is widely used as morphological markers for species identification and to assess the insect population structure. Herein, we investigated the intraspecific variation in wing geometry among populations in Thailand using landmark-based geometric morphometric analysis. females were collected from five populations in four geographical regions in Thailand. The left wings of 240 specimens were removed and digitized using 22 landmarks for analysis. While wing size variations were found between some populations, wing shape variations were detected in all. These intraspecific variations in populations indicate an adaptive response to the local environmental conditions.
（维德曼，1821年）（双翅目：虻科）是一种具有兽医和医学重要性的吸血昆虫，是泰国的主要物种。它是一种潜在的机械传播媒介，可导致家畜和野生动物感染苏拉病。翅几何形态测量学被广泛用作物种鉴定的形态学标记，并用于评估昆虫种群结构。在此，我们使用基于地标点的几何形态测量分析，研究了泰国不同种群间翅几何形态的种内变异。从泰国四个地理区域的五个种群中采集了雌性样本。去除240个标本的左翅，使用22个地标点进行数字化分析。虽然在一些种群之间发现了翅大小的差异，但在所有种群中均检测到了翅形状的差异。这些种群内的种内变异表明对当地环境条件的适应性反应。
