Protandrena

Protandrena is a genus of mining bees in the family Andrenidae. There are at least 50 described species in Protandrena. They are found from Canada through Argentina . However, there is current discussion if the Protandrena in South America are a different species.  They are solitary bees.

Morphology 
Protandrena bees are slender black bees. They frequently have yellow on the face and pronotum.  They could have red on the metasoma. They rarely have a green or blue tint.  The forewings will have two or three submarginal cells.  The photo to the right shows submarginal cells (on Lasioglossum). The three submarginal cells are near the top of the wing . 

Other Identifying characteristics include 

 middle tibial spur on the female that is finally toothed basally and becomes coarser distally, an exception to this is the subgenus Austropanurgus, where the spur is finally toothed throughout.  
 The male's S7 has a pair of large distal lobe that are constricted on the base. S7 here refers to the male genitalia 
 The gonostyli is more than half as long as gonocoxites. The apices are articulated or partly fused. The subgenus Parasarus is an exception to this, with the gonostyli being less than 1/3 as long as the gonocoxites.
