Systematics: Gannaspis miscanthi is very similar to G. glomerata in pygidial characters and especially in the features of the pygidial margin. It is distinct and easily distinguishable from the latter in lacking the following features which have been observed in G. glomerata.: the numerous short ducts which are strewn submarginally on the ventral surface through the prosoma, the metathorax, and the first abdominal segment; the sclerotized boss which occurs submarginally on the dorsal surface of the pygidium on the supposed mesal border of the fifth abdominal segment. (Takagi, 2019)
Structure: Female tests black, occurring on the upper side of leaves, crowding together at the junction of the blade and sheath. Second and third abdominal segments with filiform ducts scattered along margin on both dorsal and ventral surfaces. Anterior and posterior spiracles each with about 3–8 filiform ducts scattered anterolaterally. Subbasal intersegmental furrow of pygidium with submarginal portion divided into 2 parts both well sclerotized; a few or several, at times 5–7, ducts associated with this portion. A few ducts usually present immediately laterally to anal opening; about 4–12 ducts forming a loose cluster on intermediate area anterolaterally to anal opening. (Takagi, 2019)
