Metasoma: first tergum longitudinally costate, length equal to apical width; second tergum longitudinally costate, narrow, width about 4 times length; anterior transverse groove present, weakly sinuate; posterior transverse groove absent; third tergum costate at base, smooth apically; terga 4-7 smooth; ovipositor equal to length of metasoma.
