Gena as high as length of first flagellomere (Fig. 43). Legs completely yellow (Fig. 41). Wing entirely hyaline. Distance between crossveins 1.3 times as long as dm-cu crossvein (Fig. 41). Terminalia. Aculeus with one pairs of distinct preapical steps, as in Fig. 45. Tergite 5 of males as long as two preceding tergites.
