Subgenus Taeniandrena Hedicke, 1933

Taeniandrena have recently been revised by Praz et al. (2022; predominantly in Europe), with further Iberian revisions (e.g., Wood et al. 2021; Wood & Ortiz-Sánchez 2022; Wood 2023). This subgenus contains a large number of cryptic taxa that defy morphological recognition, and may represent an example of explosive adaptive radiation due to their pattern of sometimes extreme local endemism. An analysis of North African Taeniandrena material produced several unexpected results.
