Face slightly narrowed ventrally, finely granulate, minimal width 0.6 x eye length and 0.9 x width of frons. Malar space length 0.3 x width of mandibular bases. Genal carinae not bent outwards and obsolete ventrally, reaching hypostomal carinae far from mandibular bases in an acute angle of 70 °. Hypostomal carinae not elevated. Mesopleural discs finely granulate, without distinct punctures; specula granulate, matte; dorsal impressions slightly developed, only with fine rows of granulae. Prepectal carina narrow, absent on transversal parts. Metapleura finely granulate; coxal carinae absent. Propodeum with complete strong carinae; area superomedia as long as wide; area petiolaris slightly but widely impressed, with irregular transversal rugae. Hind femora length 4.3 x width; length of inner spurs of hind tibiae 0.65 x hind metatarsi length.
