). Dorsum testaceous to black, head and pronotal macula dark brown to black, pronotum rather widely margined in light brown to testaceous, elytra brown, palpi testaceous, tip of last palpomere not darker. Dorsum of head finely sparsely punctulate, pronotum moderately coarsely, densely punctate, punctures much larger than those of frons, interstices shining, ca. 1xpd or less. Labrum apicomedially excised, free margins weakly upturned. Pronotum with anterior margin weakly emarginate over middle 1/2; anterolateral, posterolateral, and posterosubmedial foveae very shallow.
