Rediviva (Albiviva) subgen. nov.
Type species: Rediviva (Albiviva) albifasciata Whitehead & Steiner 1994 , designated here.
The only species in this subgenus is R. albifasciata .
Diagnosis. The subgenus is monotypic and just contains R. albifasciata which is the smallest species of the genus (8–10 mm). Males can be recognized by a combination of the following characters: median lobes of S7 spatulate ( Fig. 4b View FIGURE 4 ) (not apically broadened in other subgenera); lateral lobes large and smooth, papillate on basal third (in Gigaviva lateral lobes missing; not papillate in other subgenera); apical plate of S8 distally straight ( Fig. 4a View FIGURE 4 ) (apical margin deeply cleft in Gigaviva ; apically notched, emarginate or semi-circular in other subgenera).
Females show a unique combination of a broadened hind tibia and basitarsus with the scopa consisting of densely plumose pubescence ( Fig. 3f View FIGURE 3 ) (in Redivivoides hind tibia not broadened and without plumose pubescence), bidentate mandible (tridentate in Gigaviva ) and small shiny scale-like projection on the distal-dorsal angle of the hind basitarsus (smaller than in Fig. 3e View FIGURE 3 ) (projection distinctly larger in R. intermedia , R. intermixta and R. rufipes of subgenus Deriviva , missing in all other species) in combination with the small size and distinct white apical tergal hair bands ( Fig. 3a View FIGURE 3 ) (less conspicuous yellowish or missing in all other subgenera) that only occur in this species. This is the only Rediviva species that collects oil in flowers of Colpias mollis (Scrophulariaceae) ( Steiner & Whitehead 2002, Kuhlmann & Hollens 2015).
Etymology. The new subgeneric name is a combination of the first part of the specific epithet of the type species R. albifasciata and the last part of the generic name Rediviva . The gender of the name is feminine.
Distribution. The species is only known from the western part of the winter rainfall region ( Whitehead & Steiner 2001).
