More Details

Taxonomic history

Originally described by Packard in 1865; the epithet 'smithii' likely honors an entomologist or collector, though the specific namesake is not documented in available sources. The Mastrus is placed in the Ichneumonidae, one of the largest families of with over 25,000 described species.

Data deficiency

This is extremely poorly known, with minimal collection records and no published studies specifically addressing its , , or distribution. The single iNaturalist observation suggests it is rarely encountered or underreported by naturalists.
