question
How do we explain the blunt antennal tips? T. femoratus has very clearly flattened antennal tips. There's variation in the callous, but this one isn't what I'd say strongly defined--rather, along the lines of what's seen in T. mandibularis (which also has blunt antennal tips, black bases of antennae, and red femurs like this specimen). There were three all together [image], and here's the other male [image].

There is
A pretty good webpage of Texas Cerambycids that may help...from there it looks like T thermophilus to me...

out of range
T. thermophilus is out of range and lacks annulate antennae.
