The family can be subdivided into two subfamilies, the Phytoseiinae, 

 recently studied and defined by Garman 1948, and the Podocininae, 

 a poorly defined group of genera. These subfamilies can be separated 

 as follows: 



Key to the Phytoseiidae 



1, With few setae on dorsal plate; pretarsi, caruncles, and claws on 

 all legs; dorsal plate undivided Phytoseiinae 



Without this combination of characters Podocininae 



Phytoseiinae Berlese, 1916
