Brief Summary
provided by Catalog of Hymenoptera in America North of Mexico
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 elsewhere.
