Abstract:

The fine detail of the male epiproct and aedeagus of two species of similar habitus of Western Nearctic Sweltsa, S. exquisita (Frison) and S. occidens (Frison) are illustrated using the scanning electron microscope. A new species related to S. occidens, S. durfeei sp. n., is described from Montana and Idaho. Electron micrographs of the female subgenital plate are provided of S. equisita and S. durfeei sp. n. for comparison.
