[this species was originally described by the authors of this paper; please refer to it for many more details of gall biology, insect life history, anatomy, and phylogeny]

Gall composed of many imbricated leaves resulting from a foreshortened stem, the larval cell lined with white fungal mycelium...Asphondylia sp.
