Revised key to female and male Rediviva View in CoL from the summer-rainfall region

Revision of the key of Whitehead et al. (2008), with the inclusion of R. steineri ( Kuhlmann 2012b; Melin & Colville 2022) and the new species R. vogeli sp. nov. Melin & Colville. The male of R. transkeiana is currently unknown.
