Anthidium (Gulanthidium) are robust, elongate bees which may have black and yellow markings or be predominantly yellow (Michener 2007). They range in body length from 8.5–12 mm.

Anthidium (Gulanthidium) may be confused with bees within the subgenus A. (Severanthidium) due to the carinate omaulus, scutellum, hind tibia, and hind basitarsus (Michener 2007). However, A. (Gulanthidium) can be differentiated from A. (Severanthidium) by the shape of the posterior margin of the scutellum. Further, the eyes of A. (Severanthidium) converge strongly below, which differs from A. (Gulanthidium), whose eyes only slightly converge below (Michener 2007).
Anthidium anguliventre are specialists on Cardueae (Müller 1996); however, they have also been observed visiting Centaurea sp. (Asteraceae) and Vitex agnus-castus (Lamiaceae) (Falamarzi et al. 2017). Floral associations for A. eremicum and A. rotundum are not known.
Nesting behavior is unknown.
There are no known invasives.
Anthidium (Gulanthidium) occur from Israel to Turkey, Iran, Oman, and Pakistan (Michener 2007).
