Vertex strongly reticulate inside and in front of ocellar triangle, smooth and shiny laterad to ocellar triangle; female gaster with apex pointed, second gastral tergite large, tergites 1+2 cover 0.7X the length of gaster. Similar to noyesi but with more stout flagellomeres. Also similar to eora but antennal scrobes join lower down, malar sulcus is present, vertex is smooth and shiny lateral to ocellar triangle, occipital margin with carina, postmarginal vein is longer (1.3X as long as stigmal vein). Differs from both noyesi and eora through longer apical ovipositor sheaths (2X as long as width of base in acuminata, transverse in noyesi and eora), and with hind margin of first gastral tergite straight.
