Identification
Extracted from THE POLLEN-COLLECTING BEES OF THE ANTHIDIINI OF CALIFORNIA (Hymenoptera: Megachilidae) by GRIGARICK A., A. (1968).

Anthidium pallidiclypeum Jaycox, 1963. Pan-Pac. Ent, 39(4):267. Holotype <$, San Bernardino Mts., California (CAS). Geographic range.—California.

These bees have bright yellow body and cream-colored facial markings. The males of pallidiclypeum can be distinguished by the shape of sternum VI which has no significant development of a lateral lobe and the apex of the median lobe is essentially truncate (fig. 23). In addition, the inconspicuous yellowish setal brush together with the broad lateral lobe of tergum VII (fig. 22) are useful in identifying this species. A. jocosum and cockerelli are similar in these latter respects. The females have the apical margin of the clypeus (fig. 94) with a shallower emargination between the submedian projections than the emargination of edwardsii, and have wider teeth on the margin than placitum (fig. 93).

A. pallidiclypeum is not commonly collected, parŽticularly the females, since only 11 were examined compared to 47 males. The distribution of the species is primarily limited to the lower elevations of the south coast, Transverse, and Peninsular ranges and the Owens Valley.
