Anthidium clypeodentatum Swenk, 1914
Boraginaceae: Cryptantha intermedia; Phacelia frigida. Fabaceae: Astragalus douglasii var. parishii, A. tenellus; Lotus corniculatus, L. davidsonii, L. heermannii, L. nevadensis, L. nevadensis var. nevadensis, L. oblongifolius, L. scoparius; Lupinus sp.; Trifolium pratense. Rhamnaceae: Ceanothus sp.
This species can be distinguished from all other NW Anthidium except A. psoraleae by the tomentose antennal scape and medially projected T6 of the female and the shape of T7 and S6 of the male. It can be easily separated from A. psoraleae in the female by the clypeus, which has a strongly tuberculate or toothed distal margin and T6, which lacks a distinct lateral spine or projection. The male differs in S6, which has a small, nearly triangular median lobe, and S4, which is less concave and with sparser hairs medially than in A. psoraleae.
This species is found throughout western Canada and USA and is recorded from northern Baja California, Mexico. There are two color morphs in this species. In northern portions of its range markings are cream colored and in the female absent from the face and T6. In individuals from California and adjacent Nevada maculations are yellow and are present on the face and T6.
