Casey, 1913
Tetraopes sublaevis is a of longhorn beetle in the Lamiinae, described by Thomas Lincoln Casey Jr. in 1913. Like other members of the Tetraopes, it is a milkweed . The species is known from the United States, though specific details about its and distribution within North America remain poorly documented compared to better-known such as T. tetraophthalmus and T. texanus.

Identification
Tetraopes sublaevis can be distinguished from other Tetraopes by the specific epithet "sublaevis," which refers to its somewhat smooth (less hairy) compared to the densely pubescent T. pilosus. Accurate identification to species level in this typically requires examination of antennal structure, particularly the form of the terminal antennomere, and subtle differences in coloration and body proportions. The completely divided —separated by antennal insertions into upper and lower lobes, giving the appearance of "four eyes"—is a genus-level character shared by all Tetraopes.

Similar Taxa
- Tetraopes tetraophthalmusThe common is widespread and similar in general appearance, but typically has more extensive black markings on the and different antennal proportions.
- Tetraopes pilosusThe hairy is densely covered with white and associated with sand milkweed (Asclepias arenaria), whereas T. sublaevis is described as relatively smooth (sublaevis = somewhat smooth).
- Tetraopes texanusShares the red and black color pattern but has an abruptly attenuate last antennomere that distinguishes it from similar-appearing .

Etymology
The specific epithet "sublaevis" derives from Latin, meaning somewhat or nearly smooth, presumably in reference to the relatively glabrous compared to the conspicuously hairy T. pilosus.
