Thyreodon umbrifer is a of ichneumon described by Porter in 1989. The Thyreodon belongs to the , one of the largest families of wasps. Very little published information exists about this specific species. A specimen initially identified as possibly belonging to this genus was observed in Arizona, where experts noted difficulty distinguishing Thyreodon from related genera in the southwestern United States. The genus is poorly known taxonomically, and species-level identification requires examination.

Identification
Identification of Thyreodon umbrifer requires expert knowledge of . The Thyreodon is difficult to distinguish from related genera in the southwestern United States based on field observations alone. Specimens may be confused with Rhynchophion and other Ophioninae due to similar body plans and coloration patterns. Accurate determination typically requires examination of morphological characters under magnification or microscope, including details of , structure, and .
Distribution
The has been documented in Arizona, USA. The broader Thyreodon has a distribution that includes the southwestern United States and extends into Mexico and Central America.
