Rediviva (Redivivoides) Michener 1981 , stat. nov.

Redivivoides Michener, 1981: 42 . Type species: Redivivoides simulans Michener 1981 , by original designation.

The seven species placed in this subgenus are listed in table 1.

Diagnosis. The subgenus Redivivoides comprises seven species (Table 1). Males are morphologically diverse and no apomorphies are known that distinguish them from those of other subgenera (see detailed discussion in Kuhlmann 2012b). Some can easily be mistaken for males of the subgenus Deriviva so they can only be assigned to a subgenus through the associated female.

Females lack the broadened hind tibia and basitarsus and the scopa does not consist of densely plumose pubescence for transporting floral oil that females of all other subgenera have. Instead the hind leg is narrow with the hind basitarsus only slightly broadened and the scopa consists of sparse simple bristles ( Fig. 3c ) (branched in other subgenera). Within the genus Rediviva , species of Redivivoides are unique because they do not collect floral oil for larval nourishment. Detailed descriptions of species including a discussion of morphology and biology were provided by Kuhlmann (2012b) and are not repeated here.

Distribution. Redivivoides species are known only from the winter rainfall region of western South Africa ( Kuhlmann 2012b).
