Comparative material.

CALIFORNIA. Siskiyou County. USNM 1070753, Big Springs (source) at Big Springs City Park northwest of the city of Mount Shasta, south of Spring Hill, USNM 1020771, Bundoora Spring, west of access road off FS40N44.

Remarks.

The newly reported populations closely conform to the original description of F. multifarius in all respects aside from a slightly larger maximum shell height (5.02 vs. 4.64 mm). Representative Rogue basin specimens are illustrated in Figures 3 A–C (shells), 3 D–E (opercula), 3 F–H (radula) and 4A, B, D (reproductive anatomy). Ten COI and cytB haplotypes were detected in the Rogue basin populations (Suppl. material 2-3, respectively).

The new records detailed herein extend the range of F. multifarius about 80 km northward from the Sacramento River headwaters (Fig. 2). It is not known whether F. multifarius is also distributed in the intervening Klamath River basin; the pebblesnail fauna of this large watershed is currently undescribed. Populations of F. multifarius in the Rogue basin were referred to as the Chinquapin pebblesnail, Emigrant pebblesnail, Keene Creek pebblesnail, Little Butte pebblesnail, and Pilot Rock pebblesnail by Frest and Johannes (2000, 2004, 2005).
