Figure 2 from: Kasparek M (2018) Taxonomic revision proves Trachusa pubescens (Morawitz, 1872) sensu lato to be a complex of allopatric and sympatric species in South-Eastern Europe and Western Asia (Hymenoptera, Apoidea, Anthidiini). ZooKeys 764: 111-144. https://doi.org/10.3897/zookeys.764.24581

Figure 2 Principal Component Analysis (PCA) of 26 morphometric variables of males of Trachusa pubescens s. l. (N = 132). Individuals subsequently assigned to T. balcanica sp. n. and T. maxima are shown here in a different colour. All other OUs are shown here in the same colour. One specimen from central Iran is significantly different from all other specimens of the group. The confidence ellipses show a confidence interval of 80%.
