Andrena lineolata, WARNCKE, 1968

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 : 231

Andrena lineolata differentiated from A. tiaretta and A. wollastoni

- Andrena lineolata – A. tiaretta : The species are separated in the space spanned by shape PC1 and shape PC2 when using 18 morphometric parameters (CL, FL1, FL2, FVL, FVW, HL, HW, LPW, MSW, MTW, POD, PBAL, PSL, and WL) ( Fig. 35a ). The two best ratios plotted are FL2/LPW and FVL/HW using 18 morphometric parameters. The cluster of PC1/PC2 and the clusters of the best ratios are separated.

- Andrena lineolata – A. wollastoni : The species are separated in the space spanned by shape PC1 and shape PC2 when using nine morphometric parameters (BL, FVL, HL, HW, LPW, MSW, MTW, PSL, and WL) ( Fig. 35b ). The two best ratios plotted are LPW/MTW and HW/MTW using the same nine morphometric parameters. The cluster of PC1/PC2 and the clusters of the best ratios are separated.
