Oil Collecting Bees Mostly of the Summer Rainfall Area of Southern Africa (Hymenoptera: Melittidae: Rediviva)
TLDR
The species of Rediviva (Apoidea, Melittidae) occurring in the summer rainfall region of South Africa are revised and four are described as new: R. brunnea, R. rhodosoma and R. transkeiana all attributed to Whitehead and Steiner. Expand
POLLINATOR ADAPTATION TO OIL‐SECRETING FLOWERS—REDIVIVA AND DIASCIA
OIL FLOWERS AND OIL BEES: FURTHER EVIDENCE FOR POLLINATOR ADAPTATION
TLDR
Foreleg length scales allometrically with body size in this species as 90.5% of the variance in foreleg length can be explained as a function of body length, and body size appears to be constrained by the morphology of the oil‐secreting host plant. Expand
Floral and pollinator divergence in two sexually deceptive South African orchids
TLDR
The first report of pollination through sexual deception for southern Africa is reported, and the rarity of these hybrids indicates that prefertilization barriers between the species are usually strong. Expand
Oil secretion and the pollination of Colpias mollis (Scrophulariaceae)
TLDR
The strongly congruent geographic distributions of C. mollis and R. albifasciata and their close morphological fit suggest a long and close association between plant and pollinator. Expand
Distribution, biology and flower relationships of fideliid bees of southern Africa (Hymenoptera, Apoidea, Fideliidae)
TLDR
Fideliids are ground-nesting bees, covered in a dense pale straw to brown pile, with pollen being carried on an abdominal scopa, and the rainfall pattern divides the species into early summer bees of the winter rainfall and autumn bees (4 species) of the summer rainfall areas. Expand
African fideliini: Genus Fidelia Friese (Hymenoptera: Apoidea: Megachilidae: Fideliinae)
TLDR
The tribe Fideliini comprises thirteen species in two genera, Fidelia Friese and Neofidelia Moure and Michener, with all are southern African, except for Fidelia (Fideliana) ulrikei Warncke from Morocco. Expand
The consequences of specialization for pollination in a rare South African shrub,Ixianthes retzioides (Scrophulariaceae)
TLDR
The discovery of a population in which the predicted specialist pollinator,Rediviva gigas, is present and the presence of this oil-collecting bee resulted in a mean fruit set per plant and a mean seed set increase over a previously studied population lacking the specialist pollinators. Expand
