Female without subcircular fovea in front of median ocellus (present in Labus ). Cephalic foveae absent. Mesosoma more or less flattened dorso-ventrally, distinctly longer than high. Anterior face of pronotum without medial pits or foveae, sometimes with median transverse striae present. Pronotal carina usually present dorsally. Pronotum produced at humeri. Pretegula carina generally absent or weakly developed? Epicnemial carina weakly developed. Notauli absent.
