Figs 17–20 View FIGURES 17–20

Types. Male holotype and male and female paratypes from Ingot , Shasta Co. California, collected 3 February 1959 by K. W. Gerhardt. The dissected holotype is mounted on SEM stub WS33-10, deposited in CAS .

Diagnosis. The short solenomere of the gonopod (sm, Figs 18, 19 View FIGURES 17–20 ) is poorly sclerotized and ornamented with fine, hair-like scales; the terminal zone (tz, Fig. 18 View FIGURES 17–20 ) is long with an expanded tip, but flattened, not blunt as in B. expansus . There are 18 setae in the anterior marginal row of the collum.

Etymology. The species name refers to nor thern Cal ifornia.

Description. Male holotype. Length 5.5 mm, maximum width 0.62 mm. Nonsexual characters typical for the genus. Femora of third legpair expanded. Gonopod prefemora typically flattened. Solenomere (sm, Figs 18, 20 View FIGURES 17–20 ) narrow, weakly sclerotized, straight, parallel to long axis of acropodite, set with closely spaced fine, hair-like cuticular scales. Terminal zone with flattened, slightly expanded tip (tz, Fig. 18 View FIGURES 17–20 ; Fig. 19 View FIGURES 17–20 ). Females similar in nonsexual characters to males.

Distribution. Known only from the type locality.
