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 : 234

Andrena a. tenoensis differentiated from A. a. wildpreti, A. g. gomerensis , and A. g. palmae

- Andrena a. tenoensis – A. a. wildpreti: The subspecies are separated in the space spanned by shape PC1 and shape PC2 when 18 morphometric parameters (CL, FL1, FL2, FVL, FVW, HL, HW, LPW, MSW, MTW, POD, PBAL, PSL, and WL) ( Fig. 36b ). The two best ratios plotted are MTW/OOD and FL1/LPW using the same 18 morphometric parameters. The clusters of PC1/PC2 and of the best ratios show an overlapping zone.

- Andrena a. tenoensis – A. g. gomerensis: The subspecies are separated in the space spanned by shape PC1 and shape PC2 when 12 morphometric parameters (BL, CL, FL1, FL3, FVL, HL, HW, LPW, MSW, MTW, PSL, and WL) ( Fig. 36c ). The two best ratios plotted are FL1/MSW and CL/FVL using the same morphometric parameters. The clusters of PC1/PC2 and of the best ratios are well separated.

- Andrena a. tenoensis – A. g. palmae: The subspecies are separated in the space spanned by shape PC1 and shape PC2 when 14 morphometric parameters (BL, CL, FL1, FVL, FVW, HL, HW, LPW, MSW, MTW, OCD, OOD, POD, PSL, and WL) ( Fig. 36d ). The two best ratios plotted are FL1/MSW and CL/FVW using the same morphometric parameters. The clusters of PC1/PC2 and of the best ratios are well separated.
