Prometopia Erichson, 1843

Prometopia Erichson, 1843: 279 . Type species: Nitidula sexmaculata Say, 1825 (subsequent designation by LUCAS 1920).

Diagnosis. Body oblong oval to broadly oval, more or less convex. Punctation of dorsum diffuse, sometimes intermixed with larger umbillicate punctures. Pubescence variable, sometimes finer setae intermixed with longer and/or stronger setae, sometimes pubescence fine, short and almost indistinct. Head across eyes nearly as wide as distance between anterior pronotal corners, temples moderately converging posteriad. Frons as a rule concave, frontoclypeal sulcus absent, occipital sulcus deep. Antennae with 11 antennomeres, with symmetrical, trimerous, somewhat loose club; antennomere III ca. as long as IV–VI combined. Labrum transverse to semicircular with small apical excision. Mandibles in distal half almost straight with acute, shallowly bifid tips and additional acute tooth posteriorly. Terminal palpomeres of both maxillary and labial palpus elongate, subcylindrical. Mentum large, gradually narrowed distad. Pronotum transverse, anterior margin deeply trapezoidally emarginate, anterior angles sharp, prominent. Elytra simultaneously rounded apically, diffusely punctate. Prosternal process longitudinally almost flat, its apical portion strongly dilated, subtriangular, subtruncate apically. Mesoventrite simple, situated almost at the same level as metaventrite. Metacoxal lines diverging from posterior margin of metacoxal cavity both at inner and outer ends, delimiting a characteristic subtriangular space on abdominal ventrite I. Both meso- and metacoxae widely separated. Tibiae dorsoventrally flattened. All tarsomeres narrow; tarsal claws simple.
