Artemia franciscana Kellogg, 1906

New records. WASHINGTON: Adams Co.: Columbia National Wildlife Refuge, from a lake near Shiner Lake, north of Bobcot Trail Road, south of Bobcot Loop Road, 20 April 2005, E. Kelchlin, det. D.C. Rogers, DCR-654. Grant County: saline pools along Hwy 26 between Royal City and Koren, 30 March 2007, D.C. Rogers, M. A. Hill, DCR-684.

Comments. Lake Abert is the only known Oregon locality for A. franciscana (Vanhaecke et al. 1987; Triantaphyllidis et al., 1998) and we have verified that this population is extant. Lynch (1960) reported this species from numerous small saline pools from the Omak Plateau (including Soap Lake), numerous pools south of Moses Lake, and Hot (Bitter) Lake in Washington. Triantaphyllidis et al. (1998) gives the additional Washington records of Penley Lake, Deposit Thirteen, and Lake Cameron. We found A. franciscana in numerous small pools and playas in Grant County and in one locality co-occurring with Branchinecta mackini (see comments under B. mackini below). Artemia franciscana is not known from Idaho.
