Identification
Extracted from: Grigarick A.A., & Stange L.A., (1968). The Pollen Collecting Bees of the Anthidiini of California (Hymenoptera: Megachilidae) Bulletin of the California Insect Survey Volume 9.

This species is rather difficult to distinguish from the closely related emarginatum. Males of both species have a large blackish setal brush, sternum VI (figs. 32, 35) with the lateral and median lobes longer than wide, and tergum VII (figs. 31, 34) with rather broad lateral lobes. However, tenuiflorae males usually have the lateral lobes of tergum VII much broader than in emar/linatum. Additionally, the me- dial lobe of sternum VI is usually weakly emarginate in tenuiflorae (versus entire in emarllinatum), and the apex of sternum VIII (fig. 33) is relatively nar- rower in tenuiflorae. The females of tenuiflorae usually have the sting emargination either absent or weakly developed; however, this character shows some variation. Additionally, in contrast to emarginatum, the female clypeus of tenuiflorae is flatter in profile (figs. 95 and 96). This character is also subject to variation.

A. tenuiflorae is found at the higher elevations of California's major mountain ranges but is absent in the Coast Range. Its markings are cream colored in northern California, but they become more yellowish in the mountains of southern California.
