Taxonomic note

The Rysepyris was established by R. Bohart and includes several distributed primarily in arid and semi-arid regions of North America. The species R. subtilis is listed in the UCR Research Museum catalog compiled by Douglas Yanega (2004), indicating specimen holdings but limited biological documentation. The genus is sometimes grouped with related genera such as Bembix and Stictia based on shared morphological features including clypeal structure and patterns.

Nomenclature

The specific epithet 'subtilis' (Latin: subtle, delicate, fine) was applied by W. Fox, a prolific describer of North in the late 19th and early 20th centuries. Fox described numerous bembicid during this period, many based on limited material from western North American localities.
