Thalpius dorsalis

is based on Thalpius in southeastern quadrant with elongated antennomeres (not squarish like T. pygmaeus), elytra with dark cloud posterio-medially (T. hoegei and T. rufulus without contrasting cloud), and elytral intervals distinctly convex (not flat as in T. horni of southwestern quadrant).

Taxonomic caution:

Thalpius rufulus is given only CA status in Bousquet & Larochelle (1993). The three similar Texan species noted are T. dorsalis, T. hoegei, T. horni. Furthermore, the recent world carabidae catalogue by Lorenz (2005) cites "Thalpius" as a subgenus of Pseudaptinus. Therefore, I recommend that this image be moved to either genus "Thalpius" or, preferably, to Pseudaptinus until someone can offer a reliable species identification.
