Head with occipital carina present not joining hypostomal carina; posterior ocellus separated from eye by about 1.5 times its diameter; clypeus with a strong tubercle; lower face about 1.1 times as broad as medially long, polished with sparse setae. Mesosoma with strong epomia; mesoscutum with central lobe not overhanging pronotum, transverse rugae discontinuous and sharp with short sparse pubescence; mesopleuron polished, with scattered setiferous punctures; subalar prominence inflated; epicnemial carina weak, not reaching level of lower corner of pronotum; propodeum highly polished with scattered setae, without median longitudinal depression; submetapleural carina complete.
