Remarks
- Systematics: The genus Gannaspis may be distinguished from Melanaspis Cockerell, in which the type species has long remained, by adopting the following characters as generic.1) The dorsal surface of the pygidium is not divided into well defined plate-like areas. 2) The dorsal ducts of the pygidium are scattered in a broad apical area, in the intermediate area anterolaterally to the anal opening, and along the submarginal portion of the subbasal intersegmental furrow in addition to their oblique segmental rows arising on the margin and extending anteriorly. 3) Not all elongate scleroses arising on the margin of the pygidium are clear in sclerotization and stable in occurrence. These scleroses may be homologous with those generally called paraphyses in other genera. They are, however, not developed to form a well-defined pattern in this genus. (Takagi, 2019)
- Structure: Adult female at full growth broadly obpyriform, with prepygidial region rounded and membranous, and with pygidium produced, deltoid in outline, and sclerotized especially strongly on a broad apical area. Spiracles with no accompanying disc pores. Dorsal surface of pygidium with subbasal intersegmental furrow (assumed to occur between fourth and fifth abdominal segments) interrupted to form submedian and submarginal portions. Anal opening ovate, situated posteriorly to center of pygidium and in a narrow elongate sclerotized area of derm (Takagi, 2019)
