Remarks

Terra typica: USA: ‘Fort Garland, Colorado’; for S. villosus: ‘California’; for S. jejunus: ‘British Columbia’. Casey (1892) himself synonymized S. jejunus with S. villosus . Revising all three holotypes, Puthz (1972a) found them to be conspecific and placed S. villosus in synonymy with S. dolosus . Campbell & Davies (1991) reported this species for Alaska and most provinces of Canada: Yukon Territory, Northwest Territories, Alberta, Saskatchewan, Manitoba, Ontario, Quebec and New Brunswick, without citing material.
