Anthidium (Anthidium) multispinosum are black with yellow maculations and reddish-brown coloration on the tarsi, T6 disc, laterally on S1, and medially on S6 (Gonzalez and Griswold 2013). Anthidium multispinosum have white pubescence except for brown to light ferruginous hairs on the inner hind tarsi and centers of S3–S6.

(modified from Gonzalez and Griswold 2013)
Anthidium multispinosum can be easily distinguished from all Anthidium species in the U.S. by the four spines on the apical margin of T6 and the well-developed apical spine on the outer surface of the mid tibia.
Anthidium multispinosum adults have been recorded in flight in March (Gonzalez and Griswold 2013).
Floral associations are unknown.
Nesting behavior is unknown.
Anthidium multispinosum is known from a single specimen from Durango, Mexico in the southern Chihuahuan Desert (Gonzalez and Griswold 2013). None are known to occur in the U.S. or Canada.
