Anthidium (Nivanthidium) are robust, shiny, black bees with limited markings on the abdomen (Michener 2007). Along the lateral margin of the abdomen, there are dense areas of white hairs. They range in body length from 9–14 mm (Michener 2007).
(modified from Michener 2007)
Anthidium (Nivanthidium) are superficially similar to bees within the genus Serapista because they are both large, robust black bees with dense white hairs on the abdomen (Michener 2007). However, A. (Nivanthidium) can be differentiated from Serapista due to the weak axillar suture, carinate pronotal lobe, and large, flat scutellum (Michener 2007).
Floral associations are unknown.
Nesting behavior is unknown.
Anthidium (Nivanthidium) consists of one species, A. niveocinctum, which is not known to occur in the U.S. or Canada (Michener 2007).
