Range and Identity
A modern reassessment of the California Roach complex recognizes Hesperoleucus mitrulus as Northern Roach. The current taxonomic catalog retains that species. Older records under Hesperoleucus symmetricus may cover multiple modern species, so their broad distribution should not be copied into this account.
Habitat and Behavior
The original description is linked to Drew Creek in Oregon’s Drews Valley. That locality provides historical context for the northern drainage identity. Freshwater occurrence is established, but a precise habitat description should come from the actual stream record rather than assumptions drawn from all California roaches.
Size and Life-History Records
The available general fish reference redirects the name to California Roach. Its maximum length, broader range and life-history summary are therefore not treated as species-specific Northern Roach evidence. No maximum mass is calculated to fill that gap, and the retained inventory identity remains unchanged.
Field Note
Use the modern species name and the upper Pit locality together. This keeps a northern record distinct from coastal and central California members of the complex.
