Anthemurgus
passionflower bee
Anthemurgus is a subgenus within Protandrena (family Andrenidae) containing at least one confirmed species, P. (Anthemurgus) passiflorae, commonly called the passionflower bee. This bee is notable for extreme host-plant specialization (monolecty) on Passiflora lutea, the yellow passionflower. The subgenus has undergone repeated taxonomic revision, having been treated as a monotypic genus, a subgenus of Pseudopanurgus, and currently as a subgenus of Protandrena. A chromosome-level genome assembly has been completed for the sole species.
Macrotera
Goblin Bees
Macrotera is a genus of mining bees (Andrenidae) native to North America, with approximately 30 species. These bees range from 2.0 to 16.0 mm in body length and are predominantly found in desert regions of the United States and Mexico. The genus was segregated from Perdita by C.D. Michener in 2000. Most species exhibit extreme pollen specialization (oligolecty), with documented associations to Sphaeralcea and Cactaceae.
