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.
