In 1885 von Ernst Girschner described a remarkable Carcelia-like fly from the Thuringian district of central Germany which was noteworthy in that it possessed a number of paired plumose hairs on the head. The facial hairs were the more noticeable as they originate not on the facialia or parafacialia as normal bristles, but apparently in the ptilinal groove between the two regions, two pairs being found here and three pairs on the anterior part of the front.
