That's interesting Toby. Yeah, some discrepancies and difference of interpretation will always have to be expected with range maps as you know.

Is there an obvious, or notable difference of habitat that you and/or others have noticed there that is not favorable to lindheimeri in the more southern counties you mentioned?. And are those three disjunct areas of populations more like the habitat in the northern range?

I am guessing the Nueces River basically acts as sort of a natural border for certain fauna, but certainly it isn't vast enough to prevent linheimeri from ever being able to populate the other side to some extent. Especially over countless millenia I would think.

Just thinking out loud a bit here, as I have never been in that area like you and many others have.
