The aim of this study was to analyze the 12 species which belong to the subgenus Bombus (Thoracobombus) by identifying, collating and testing the applicability of geometrics morphometrics for distinguishing the species. This was carried out on 133 females and 42 males which were collected from various localities in Turkey. After digitizing landmarks on the right fore wings, 2-dimensional Cartesian coordinates were calculated and by Procrustes analysis the coordinates were standardized and superimposed. Principal Components Analysis (PCA) and Canonical Variates Analysis (CVA) were performed to show the distribution of all species. Then, deformations which appeared in thin-plate splines were observed. Mean values of all the specimens were calculated and Sequential, Agglomerative, Hierarchical, and Nesting clustering method (SAHN) was performed with these data to obtain the dissimilarity trees. It can be concluded that all species were found to have consistently different wing shapes from each other. In females, the species B. armeniacus, B. mesomelas and B. pomorum which resemble each other, were also found to be similar based on their wing morphometry. Both in females and males, the subspecies B. sylvarum citrinofasciatus and B. sylvarum daghestanicus and the species B. humilis and B. laesus exposed high similarity in wing morphometry. In males, results showed that the species B. armeniacus and B. mesomelas and the species B. humilis and B. zonatus have very similar wing shape.
本研究的目的是通过识别、整理和测试几何形态测量学在区分熊蜂属（胸熊蜂亚属）12个物种方面的适用性来对这些物种进行分析。研究对象为从土耳其各地收集的133只雌性和42只雄性熊蜂。在对右前翅上的地标进行数字化处理后，计算二维笛卡尔坐标，并通过普氏分析对坐标进行标准化和叠加。进行主成分分析（PCA）和典型变量分析（CVA）以显示所有物种的分布情况。然后，观察薄板样条中出现的变形。计算所有标本的平均值，并使用这些数据进行顺序、凝聚、层次和嵌套聚类方法（SAHN）以获得差异树。可以得出结论，所有物种的翅形彼此之间始终存在差异。在雌性中，形态相似的亚美尼亚熊蜂、黑腹熊蜂和苹果熊蜂，根据其翅形态测量结果也被发现相似。在雌性和雄性中， sylvarum citrinofasciatus亚种和sylvarum daghestanicus亚种以及卑微熊蜂和拉埃苏斯熊蜂在翅形态测量上表现出高度相似性。在雄性中，结果表明亚美尼亚熊蜂和黑腹熊蜂以及卑微熊蜂和条带熊蜂的翅形非常相似。
