Gretna Evans, 1937  

Evans (1937) established this genus for six Afrotropical species and designated Hesperia cylinda Hewitson   the type species. 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.
