. Body length 12.5–14.5 mm, mean ♀ 13.7 mm, mean ♂ 13.0 mm. Head slightly wider than pronotum. Head black with metallic blue to green reflections mostly limited to the lateral ridge of the supraorbital region. Fine to marked rugosity often present on the frons and vertex. All head portions glabrous except for two supraorbital setae next to each eye. Frons concave in median area, especially in male, bulging towards slightly convex near anterior margin, clearly delimited from clypeus, gradually blending into vertex. Genae black often with weak metallic green to violet reflections, with shallow, longitudinal striae, gradually ending at border of vertex. Clypeus shining black, apparently lacking coloured reflections. Male labrum tridentate with 6–8 setae, central area pale ochre-testaceous, with a thin dark-brown to black border posteriorly and sometimes anteriorly, dark-brown to black laterally; in some populations, the pale central area of the labrum may exist as a small spot, up to one-quarter of the total labrum surface; female labrum tridentate with 6–8 setae, entirely dark-brown to black with polished metallic cupreous to green reflections.
