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 : 229-231

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

- Andrena gomerensis – 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, FVW, HL, HW, MSW, MTW, OCD, OOD, PBAL, POD, PSL, and WL) ( Fig. 34d ). The two best ratios plotted are HW/MTW and HL/OOD using 15 morphometric parameters. The cluster of PC1/PC2 and the clusters of the best ratios are separated.

- Andrena gomerensis – A. tiaretta : The species are separated in the space spanned by shape PC1 plotted against shape PC2 when using 11 morphometric parameters (BL, FL2, FVL, FVW, HW, LPW, MSW, MTW, PBAL, PSL, and WL) ( Fig. 34e ). The two best ratios plotted are FVL/MTW and FL2/HW using eight morphometric parameters (FL2, FVL, HW, MSW. MTW, PBAL, PSL, and WL). The cluster of PC1/PC2 and the clusters of the best ratios are separated.

- Andrena gomerensis – A. wollastoni : The species are separated in the space spanned by shape PC1 and shape PC2 when using nine morphometric parameters (BL, HL, HW, LPW, MSW, MTW, OCD, PSL, and WL) ( Fig. 34f ). The two best ratios plotted are LPW/OCD and HW/WL using nine morphometric parameters. The cluster of PC1/PC2 and the clusters of the best ratios are separated.
