Identification
As a member of Stenogomphurus, this likely exhibits the -characteristic clubbed with expanded terminal segments, particularly pronounced in males.

Distribution
Eastern North America. Documented occurrence records indicate presence in the United States, with the range centered in the southeastern and mid-Atlantic regions. Precise range boundaries require verification from primary sources.
Similar Taxa
- Stenogomphurus consanguisOverlapping range in eastern North America; both share -characteristic clubbed and require careful examination of abdominal patterning and male terminal appendages for reliable separation.
- Gomphus speciesHistorical confusion due to original placement in Gomphus; superficially similar clubbed structure, but Stenogomphurus is distinguished by specific wing venation and genitalic characters.

Originally described as Gomphus rogersi Gloyd, 1936. The was subsequently transferred to Stenogomphurus, a erected to accommodate several North American clubtail species previously placed in Gomphus. The genus Stenogomphurus is distinguished from Gomphus primarily on the basis of male genitalic and wing venation characters.
