Notes

The specimen closely agrees with Bouček ’ s diagnosis in his key in which the scutellum ends with two broadly rounded processes that are separated by a distance as broad as the length of each process ( Figure 7 e); mesoscutum closely punctate especially laterally, but somewhat sparser in the middle; wings whitish to transparent. It agrees very well with Ruschka ’ s description in having slender antennae that are sharply pointed at the apex, slightly submoniliform ( Figure 7 d), scutellar sulcus gradually bifurcates posteriorly in the form of an inverted Y ( Figure 7 e); petiole finely shagreened, with a very fine, hardly seen carina at posterior end; metasoma dark metallic green ( Figure 7 c); wings glassy hyaline.
