Global Range: (Zero (no occurrences believed extant)) This species formerly occurred in Rock Lake in Whitman Co. (Meyer and McCafferty, 2007). Historical (1931) museum specimens are also documented for Corvallis, Benton Co., Oregon (Meyer and McCafferty, 2007).

Comments: Larvae were never known for this species (P. McCafferty, personal communication, December 2003).

Non-Migrant: No. All populations of this species make significant seasonal migrations.

Locally Migrant: No. No populations of this species make local extended movements (generally less than 200 km) at particular times of the year (e.g., to breeding or wintering grounds, to hibernation sites).

Locally Migrant: No. No populations of this species make annual migrations of over 200 km.

Note: For many non-migratory species, occurrences are roughly equivalent to populations.

Estimated Number of Occurrences: 0 (zero)

Comments: This species formerly occurred in Rock Lake in Whitman Co. (Meyer and McCafferty, 2007). Historical (1931) museum specimens are also documented for Corvallis, Benton Co., Oregon (Meyer and McCafferty, 2007).

Rounded Global Status Rank: GH - Possibly Extinct

Reasons: The species, which is unknown as larvae and unaccompanied by habitat data, has not been reported since 1924 in Washington and 1931 in Oregon. The fact that it is so distinctive, as shown by male genitalia leaves little doubt that it is valid. If it were from a well-collected area of North America, the circumstances would call for consideration of it as extinct. However, because British Columbiais relatively poorly sampled as far as their mayfly fauna is concerned, it would be prudent for the time being to assume that it could potentially still be extant.

Global Protection: None. No occurrences appropriately protected and managed
