This is the largest subgenus of Perdita. Six groups of species are currently recognized and, 

 although some of these groups have been divided into subgroups in the existing classification, no 

 attempt has been made to reflect these subsidiary units in this catalog. The six recognized spe- 

 cies groups are arranged in accordance with the current classification of this subgenus.
