Bathanthidium are small bees ranging in body length from 5.5–9 mm. Their coloration varies from all black to black with yellow medially broken bands on the terga (Michener 2007).
Bathanthidium contains 13 species within 3 subgenera (Michener 2007; Ascher and Pickering 2016b); none are known to occur in the U.S. or Canada.
(modified from Michener 2007)
Bathanthidium may be confused with Rhodanthidium and some Trachusa due to a number of shared characters; however, Bathanthidium can be differentiated from these genera by the presence of fovea behind the propodeal spiracle (these fovea can be small in the subgenus Manthidium (Michener 2007).
There are no known invasives.
Bathanthidium has been observed visiting Lactuca sibirica, Sedum aizoon, and Lespedeza bicolor (Игнатенко 2012).
Bathanthidium have been observed creating nests out of resin in preexisting burrows in wood and plant stems (Romankova 1988).
Bathanthidium is an Asiatic genus that occurs in China, Taiwan, Burma, Laos, eastern Siberia, and Korea (Michener 2007; Soh et al. 2016).
