Epeolus americanus
?

Devil's advocate
I guess I was playing Devil's advocate in proposing
Epeolus americanus
.
The following four
Epeolus
species are expected in this area:
E. americanus
,
E. compactus
,
E. mesillae
, &
E. minimum
.
E. mesillae
can be excluded based on number of submarginal cells, and
E. minimum
does not resemble well overall.
A fifth potential candidate, with records from distant Lake Tahoe area, is
E. scopulus
, but its legs are supposed to be almost all black.
This leaves
E. americanus
and
E. compactus
.
E. americanus
' scutum has mostly dark-coppery pubescence, except for two white lines; which doesn't seem to match very well.
But I didn't find any stonger evidence for excluding it ...
E. compactus
matches fairly well, but I can't discern:
- scutum weakly rugose, and with sparse, white or pale coppery pubescence; and
- vertex with sparse, erect, long, off-white hairs around ocelli.
These could be due to the lack of detail in the photos.
I therefore agree that it is most likely
E. compactus
;
but I would like to make a stronger case for excluding
E. americanus
.
