Types: Male holotype from WASHINGTON: Cowlitz Co., Germany Creek Road 5.5 mi N of Stella at SR-4, elev. 140 m., 46.2593°N, - 123.1344°W, collected 22 November 2003, by W. Leonard, C. Richart; GoogleMaps   male paratype from Germany Creek Road 5.3 mi N of Stella at SR-4, elev. 140 m., 46.2565°N, - 123.1356°W, collected 11 November 2004, by W. Leonard and C. Richart GoogleMaps   .

Diagnosis: The posterior gonopod coxites are similar to those of the preceding species but the anterior gonopods are quite different, lacking the midlength shelf and sharp taper, and with three large subterminal teeth.

Etymology: This species takes its adjectival name from Germany Creek, where the holotype and paratype were collected.

Description: Male holotype: Length, 9.0 mm. Nineteen ocelli in triangular group. Metazonites with well-developed shoulders, segmental setae long, curved, acute. Color as described for B. pacifica   . Legpairs one and two reduced, pairs three to five enlarged, sixth pair somewhat smaller, seventh pair approximately same size as postgonopodal legs; prefemora three to five with conspicuous knobs. Anterior gonopods ( Figs. 220 View FIGS , 222 View FIGS ) with mesal branches less than one-third size of lateral branches, broadly flattened in lateral view; lateral branches curved, with large, wing-like expansion anteriorly, bearing three triangular subterminal teeth. Posterior gonopod coxites ( Figs. 221 View FIGS , 223 View FIGS ) with pseudoflagellar branch tightly reflexed, not strongly tapering, two large fimbriate branches, lateralmost embraces pseudoflagellum, mesal branch subtends small pore. Tenth coxae and eleventh prefemur as usual.
