). Dorsum brown to light brown, head and pronotal macula dark brown to black, palpi light brown to testaceous, tip of last palpomere not darker. Dorsum of head and pronotum moderately densely punctulate, more sparsely punctulate on macula than on surrounding areas, interstices shining; punctures of frons disc slightly smaller than 1xef, on pronotal disc slightly larger than 1xef, interstices ca. 2–3xpd or slightly larger; punctures of clypeus obsolete. Labrum apicomedially excised. Pronotum with anterior margin weakly emarginate over middle 1/2; anterolateral foveae moderately deep, posterolateral pronotal foveae very shallow, posterosubmedial foveae very shallow.
