Mesoscutum and mesoscutellum dull, granulate ( Fig. 151A ). Notauli incomplete, reaching approximately 0.7 × length of mesoscutum. Metanotum dull, reticulate rugose. Metapectal-propodeal disc dull, reticulate rugose, about as long as propodeal declivity; propodeal declivity reticulate rugose, without longitudinal keels. Forewing ( Fig. 151D ) with three dark transverse bands; distal part of 2r-rs&Rs vein longer than proximal part (11:6). Protarsomeres in following proportions: 16:3:6:18:30.
