Andrena tiaretta differentiated from A. wollastoni

- Andrena tiaretta – A. wollastoni : The species are separated in the space spanned by shape PC1 and shape PC2 when using 15 morphometric parameters (BL, FL1, FL2, FL3, FVL, FVW, HL, HW, LPW, MSW, MTW, OCD, OOD, PSL, and WL) ( Fig. 35c ). The two best ratios plotted are FVL/OOD and HL/WL using the same 15 morphometric parameters. The cluster of PC1/PC2 and the clusters of the best ratios are separated.
