Kratochwil, Anselm & I, Canary, 2020, Revision of the Andrena wollastoni group (Hymenoptera, Anthophila, Andrenidae) from the Madeira Archipelago and the Canary Islands: upgrading of three former subspecies and a description of three new subspecies, Linzer biologische Beiträge 52 (1), pp. 161-244 : 229

Andrena dourada differentiated from A. gomerensis , A. lineolata , A. tiaretta , and A. wollastoni

- Andrena dourada – A. gomerensis : The species are separated in the space spanned by shape PC1 and shape PC2 when using 13 morphometric parameters (BL, FVL, FVW, HL, HW, LPW, MSW, MTW, OCD, OOD, PBAL, PSL, and WL) ( Fig. 33f ). The two best ratios plotted are FVW/LPW and FVL/OCD (using the same morphometric parameters). The cluster of PC1/PC2 and the clusters of the best ratios are clearly separated.

- Andrena dourada – A. lineolata : The species are separated in the space spanned by shape PC1 and shape PC2 when using 15 morphometric parameters (BL, FL2, FL3, FVL, HL, HW, LPW, MSW, MTW, OCD, OOD, PBAL, POD, PSL, and WL) ( Fig. 34a ). The two best ratios plotted are LPW/POD and HW/MTW (using the same morphometric parameters). The cluster of PC1/PC2 and the clusters of the best ratios are clearly separated.

- Andrena dourada – A. tiaretta : The species are separated in the space spanned by shape PC1 and shape PC2 when using seven morphometric parameters (FVL, HL, HW, MSW, MTW, OCD, and PSL) ( Fig. 34b ). The two best ratios plotted are FVL/HW and HL/PSL (using the same morphometric parameters). The cluster of PC1/PC2 and the clusters of the best ratios are clearly separated.

- Andrena dourada – A. wollastoni : The species are separated in the space spanned by shape PC1 and shape PC2 when using five morphometric parameters (BL, HL, HW, PSL, and WL) ( Fig. 34c ). The two best ratios plotted are FVL/HW and HL/PSL using 11 morphometric parameters (BL, FL1, FVL, FVW, HL, HW, MSW, MTW, POD, PSL, and WL). The cluster of PC1/PC2 and the clusters of the best ratios are separated.
