We have treated three palm feeding species in Cock et al . (2014), but G. cylinda , the type species, is recorded to feed on Marantaceae and so is treated here. Larsen (pers. comm. 2014) considers G. cylinda out of place with the other members of the genus, all of which are likely to be palm-feeders, so it is likely that one (or more) new genera will need to be established for them.
