I have seen many females, all black, with the classic red "hour glass" (way too many of them, actually) but I have never seen one like this?

|It appears to be a male from what I can see of the palps. There's more than one widow spider, your location could help (you can add it to your profile).|

yes, I had looked on there...thought maybe a brown widow? but I am in northern Utah--
I'm primarily interested in learning how fearful I need to be about this spider because it is kind of 'in my way'

|I've come to the conclusion it's 'probably' a Brown Widow, Latrodectus geometricus. I checked one of your photos in the plant database and found you are in Utah, which is in it's distribution or at least adjacent to.|
The Brown Widow Spider does have an hourglass but it is typically an orange shade rather than the vivid red of a black widow

|Or perhaps the Western Black Widow, L. hesperus, |
males brown and can have orange hourglass

|That seems possible! |
Latrodectus hesperus ...
The preserved male has a black 'chest' where the live one has a pale median stripe on this Utah uni site .. they only show Latrodectus Hesperus.
Photos on the Californian edu site show a pale stripe ..
There's only one photo showing the 'chest' of the male Latrodectus geometricus ...
One on bugguide of Latrodectus hesperus shows all black 'chest' ..
