Genus: Duckeanthidium Moure and Hurd, 1960
Common name: none
Duckeanthidium are robust but slightly elongate bees that range in body length from 8.5–16.0 mm (Michener 2007). Some have solid black integument with limited yellow maculations, while others have abundant yellow maculations and a brown abdomen (Michener 2007).

Duckeanthidium may be confused with other large anthidiines, such as Epanthidium and Hypanthidioides, which have juxtantennal carina and similar body coloration patterns. Duckeanthidium can be distinguished by the combination of characters above.
There are no known invasives.
Duckeanthidium thielei is believed to be a specialist on Bauhinia (Fabaceae, Caesalpinioideae) (Thiele 2002). Little is known about the floral resources utilized by the remaining species of Duckeanthidium.
The nesting habits of most species of Duckeanthidium are unknown. Duckeanthidium thielei provision cells with dry pollen partitioning cells. They close their nests with a light-yellow resin that turns light cream-colored and becomes exceptionally hard (Thiele 2005). Specializing in wet forest environments, nests are formed high in the canopy of live trees in holes in wood blocks (Thiele 2002). Their nesting location in the canopy may be one reason that Duckeanthidium are uncommon in collections (Michener 2002). Females seal themselves within nests overnight by temporarily capping nests with a soft resin-like material, which is removed before resuming diurnal activity (Thiele 2005).
