A new species account for Eubranchipus hesperius n. sp. (Western Ethologist Fairy Shrimp--unofficial name), Order Anostraca, prepared by Thalia Grant, has now been posted on E-Fauna BC.  In her write up, Thalia says: 

"Eubranchipus hesperius was recently declared a new species, separate from Eubranchipus serratus Forbes 1876 (Rogers, 2014). It differs from E. serratus in the morphology of its antenna, brood pouch and abdomen, and in its geographical range; E. hesperius is found in North American transmontane and cold desert bioregions west of the Great Plains. E. serratus is now considered restricted to the Appalachian/Ozark bioregions and eastern Great Plains of the United States."

"Eubranchipus hesperius has been recorded in British Columbia, eastern Washington and Oregon, Idaho, western Montana, northwestern California, northeastern Nevada and central Arizona. In British Columbia, E. hesperius has been found at altitudes of 600 to 1700 meters around Merritt, south of Merritt on Iron Mt., Selish Mt., Gillis Mt. and Shovelnose Mt., southwest and southeast of Kamloops, and in Curzon in the southeastern part of the province (Smithsonian collections, RBCM collections, Ian Gardiner, Thalia Grant)."
