Here is the final set of distribution maps from the posters on the sixth floor of BYU's Widtsoe Building.
[1] This last one comes from Daniel Mulcahy, who is now a professor at Utah State University. He produced a poster about North American night snakes from the species,
Hypsiglena torquata.
It is comprised of several subspecies populations (though Mulcahy argues that several represent distinct species
[2]). His poster included a map showing the ranges of most of the subspecies. The rest I was able to deduce or find on the internet.
As before several of the maps depicted species with such narrow ranges that I created an inset so that they could be better visualized. However, this time there were a few new wrinkles. Some of the species of night snake are only found on a single island. Often these islands were so small that they were still hard to pick out in the inset. So I added a red arrow to point to the correct island. And in one case, I had to use
two insets
and an arrow!

Once I had the maps created and uploaded to Wikimedia Commons, I inserted them into the taxoboxes of existing Wikipedia articles:
Hypsiglena,
Hypsiglena torquata,
Hypsiglena torquata jani, and
Hypsiglena torquata nuchalata.
Notes:

his map for the Harpy Eagle almost a year ago.

[3] Many researchers, including Mulcahy, consider these three subspecies (
dunklei,
jani, and
texana) to be the same and call them, collectively,
Hypsoglena torquata subsp.
jani). I decided not to take sides, so I included all three on this map.
