- 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) (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) (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) (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) (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) (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).
