Genetic and multivariate morphometric analyses unveil cryptic diversity in sympatric populations of the Mediterranean wool carder bee, identified as Anthidium undulatum Dours, 1873 (Hymenoptera: Megachilidae: Anthidiini)

Face and apical terga of typical females of Anthidium: A, D A. undulatum; B, E A. libanicum sp. n.; C, F A. wahrmani stat. nov. Note the color of the antennal scape (black in A. undulatum and A. libanicum), the color pattern of T6 (black in A. undulatum, yellow with black apicomedial wedge-shaped incision in A. libanicum sp. n. and A. wahrmani stat. nov.), and overall tone of yellow (pale yellow in A. libanicum sp. n., dark bright yellow in A. undulatum and especially in A. wahrmani stat. nov.).
