Paired sperm funnels open in the ventral part of septum 10/11, each leading to a ciliated vas deferens, which joins the atrium at the middle of the ampulla. Vas deferens longer than atrium, length about 200–290 µm, diameter 17–23 µm. Atrium consists of a small globular to ovate ampulla and a long inflated duct; a short neck (20–30 μm long by 30–45 μm wide) connects the ampulla to the atrial duct; this section has narrow columnar epithelium (

. Known from several localities in central and northern California. Sites were small to mid-sized, gravel-cobble bed streams in relatively undisturbed, foothill settings; worms were collected from riffle habitats with coarse sediments. Sites on Coyote and Chalone creeks are intermittent, typically losing surface flow in summer.
