McCafferty WP and Newell RL. 2007. NOTES ON GEOGRAPHIC DISTRIBUTION, Insecta, Ephemeroptera: Range extensions and new state records from far western Montana, U.S.A., W. Patrick McCafferty, Robert L.

The U.S.A. state of Montana is the third largest in size (380,838 km2) of the conterminous states but has been one of the poorest known states in terms of its specific Ephemeroptera (mayfly) fauna (McCafferty 2001). This note represents a considerable step towards rectifying that situation by providing new record data for species collected in the far western Rocky Mountain region of Montana. The exact study area to which our new data apply includes all of Montana west of the Continental Divide, and all of Glacier National Park, which in the north extends both west and east of the Continental Divide (Figure 1). Thus, locales in the Montana records herein are from Deer Lodge, Flathead, Glacier, Granite, Lake, Lewis and Clark, Lincoln, Mineral, Missoula, Powell, Ravalli, Sanders, and Silver Bow Counties. We contribute new Montana record data for 38 species. Previously, 49 species were known from western Montana based on published data, with Traver (1934; 1935) being the major provider of previous records.
