The females vary in size from 5 to 11 mm. This species is closely 

 related to phoenix (Fox), see discussion under that species. A note 

 on two of the specimens collected by Cockerell states that this species 

 is parasitic in the nests of Diadasia species. The genitalia of the 

 male is exactly similar to that of phoenix and is therefore not fig- 

 ured. Dasyniutilla foxi var. arizonica Cockerell is a specimen of this 

 species in which the pubescence of the head and thorax is whitish.
