While most of the known host information suggests that these bees are cleptoparasites in the 

 nests of eucerine bees (e.g., Melissodes, Peponapis, Svastra, and Xenoglossa), at least some spe- 

 cies are known to be parasites of other Anthophoridae (e.g., Anthophora, Centris) as well as Col- 

 letidae (Ptiloglossa), Oxaeidae (Protoxaea) and Halictidae (Noynia).
