This genus was formerly placed by Townes in the Cryptini, where it was a member of his now 

 defunct subtribe Echthrina. Townes (1970) said little concerning his placement of Helcostizus in 

 the Hemitelini, which leads me to suppose that he placed it here because he did not know what 

 else to do with it. He mentioned Helcostizus as one of a number of genera showing "convergence 

 toward" his newly erected subtribe Gabuniina (Cryptini), but said that in certain cases (without 

 saying which cases) it is uncertain whether these genera should be placed in the Gabuniina or el- 

 sewhere.

 restaurator yukonensis (Ashmead). Northwestern N. W. T. w. to Alaska, s. to Ariz, and Calif. 

 Host: Plectura spi)iicauda Mann. Townes and Townes (1962) distinguished rufiscutuni 

 Cushman as a separate subspecies, but the material they studied included nearly as 

 many specimens which they classified as intermediate between rufiscutH)n and 

 yukonensis as there were specimens identified as rufiscutuni; therefore, I feel it is not 

 practical to recognize rufiscutuni as a distinct subspecies.
