Treatment

Cottus ohlone ohlone Moyle and Campbell 2022 . Nominate subspecies, Ohlone Riffle Sculpin.

Holotype and paratypes. Same as for the species, C. ohlone .

Diagnosis. Distinguished from other members of the C. gulosus complex as a distinct lineage as determined by genetic and genomic studies ( Baumsteiger et al. 2014, this study) and by its distinctive distribution ( Fig. 3 View FIGURE 3 ).

Description. Same as for C. ohlone above ( Fig. 1 View FIGURE 1 ).

Distribution. Largely restricted to upper portions of streams in and around the highly urbanized (e.g., San Jose) Santa Clara Valley, including the upper Guadalupe River and upper Penitencia Creek, which is tributary to Coyote Creek. All known locations occur west of the Coast Range (Diablo Range), in the hills around the Santa Clara Valley, or in streams flowing into San Francisco Bay from the Coast Range. The southernmost sample collected was from Bird Creek, near Hollister Hills (see Baumsteiger et al. 2014). The northernmost location known was San Mateo Creek ( Jordan and Everman 1896) from which they have been extirpated ( Leidy 2007).
