Fore wing (L:W = 329.5: 95.5) and hind wing (L:W = 279.5: 61.4) weakly infuscate.

METASOMA ( Figs 5 , 6B ). L: W = 286.0: 146.0; T1 longitudinally costate, space between costae predominantly smooth; T2 entirely longitudinally costate with shorter costae in between them on posterior half, except for a smooth patch laterally with setigerous punctae; T3 longitudinally costate on anterior half with foveae between costae, smooth on posterior half, laterally smooth with sparse setigerous punctae; T4 medially smooth with setigerous punctae, posteriorly smooth, remainder areolate, setose; T5 areolate, setose except for smooth posterior margin; T6 anteromedially punctate, with two densely setose, large lateral teeth and a median lobe; T1 and T2 with sparse lateral setae, T3–T5 with dense setae posterolaterally; length and width of tergites T1–T 6 in ratio of 46.0:42.0, 68.0: 56.0, 92.0: 136.0, 42.0: 134.0, 20.0:88.0, 20.0: 42.0, respectively.
