I've researched much material but am not seeing any mention of this. Any reliable way to tell gender??

You can find some info here: Phrynosoma.org

It's pretty weak actually and needs some revamping. I've been meaning to get around to this actually.
In general, the males have the bulges just aft of the vent, whereas the females will generally taper off rather quickly.
Some species have enlarged post-anal scales (Usually just one large scale on each side) that help indicate a male.
Enlarged femoral pores along the underside of the rear legs is also an indicator of a male.
Hope this helps some.

Here are a few photos of cornutum and one Goodei that should help to show the difference between male and female.

The photo below shows the hemipene bulges and the post anal scales. Those enlarged scales will be absent on females. These are species dependent and not all species will show them. As you can see above, the male cornutum does not have enlarged scales. Solare do show them.
