Variation
Translucent patches are absent in ZFMK-HYM-00036868 and the proximodorsal margin of the gvc is slightly concave in ZFMK-HYM-00036868. The posterolateral processes of the gena are differently shaped in the

Condition of
type
material
In the
holotype
, left F7–F9 and right F8 and F9 and the right hind wing are missing. The posterior part of the metasoma is missing, thus the body length measurement is not precise.
