Holotype.— Male, Utah, Cat. No. 26212, U.S.N.M. 



The type specimen lacks both wings and antennae. However, 

 the structure of the genitalia is so characteristic that it may be easily 

 recognized from that structure alone. External structural characters 

 are used in the key to the males to separate this from other species.
