Overview

Apianthidium range in body length from 12–13 mm and have mostly yellow to yellow-reddish head and thorax. Their terga are mostly yellow at the base with the posterior half of each tergum black (Michener 2007).

Diversity

Apianthidium contains one species, A. apiforme (Michener 2007); none are known to occur in the U.S. or Canada.

Diagnostic characteristics

(modified from Michener 2007 unless otherwise stated)

• Arolia absent.
• Hind tibial spurs with apices strongly hooked.
• Juxtantennal carina absent.
• Middle tibia with anterior margin strongly convex.
• Middle tibia as broad, or nearly as broad, as hind tibia.
• Preoccipital ridge without carina (Pasteels 1969).
• Female mandible with three or four teeth.
• Female tarsal claws bifurcate.
• Male T7 simple, unmodified (Pasteels 1969).

May be confused with

Apianthidium resembles Trachusa due to similar body form and size. However, Apianthidium can be differentiated from Trachusa by the distinctly hooked apices of the hind tibial spurs, and the middle tibia as broad, or nearly as broad, as hind tibia (Michener 2007).
