TYPE SPECIES: Paracolletes sexmaculatus Cockerell, 1914a .

DIAGNOSIS: This is a genus of robust bees with black, nonmetallic integument with apicolateral bands of white setae on metasomal terga II– IV. The metanotum has a low median tubercle. It superficially resembles Protomorpha Rayment but lacks impressed facial foveae.

ETYMOLOGY: The new generic name is a combination of Ancient Greek prefix hexa – (ἑξα –, forming compound words with the sense of “six”) and prōktós (πρωκτός, meaning, “anus” or “rectum”). The gender of the name is masculine.
