Aspects of the nomenclature and classification of the subtribe Strumariinae are corrected and emended as follows: Hessea subgenus Myophila (Snijman) Snijman and Strumaria subgenus Carpolyza (Salisb.) Snijman are described, and Strumaria section Gemmaria (Salisb.) Snijman is validated; the correct author citations for several names in Strumaria that were invalidly published by Jacquin are established; and a complete infrageneric synopsis for the actinomorphic-flowered taxa of subtribe Strumariinae is provided.

The monotypic genus Bryomorphe Harv. is found to be homotypic with Klenzea lycopodioides Sch.Bip., which is considered to be a later synonym of Dolichothrix ericoides (Lam.) Hilliard & Burtt, and Bryomorphe is thus a synonym of Dolichothrix. The new genus Muscosomorphe J.C.Manning is proposed to accommodate the species previously included in Bryomorphe as B. aretioides (Turcz) Druce, along with the new combination M. aretioides (Turcz) J.C.Manning.

The new combinations Colchicum burchellii (Baker) J.C.Manning & Vinn. and C. burchellii subsp. pulchrum (Schltr. & K.Krause) J.C.Manning & Vinn. are provided for the taxa currently known respectively under the names C. coloratum subsp. burchellii (Baker) J.C.Manning & Vinn. and C. coloratum J.C.Manning & Vinn., nom superfl.

The correct author citations for several names in the genera Drimia (Hyacinthaceae) and Eriospermum (Ruscaceae) that were invalidly published by N.J. Jacquin are provided. The later validation dates for these names do not have implications for their nomenclatural priority. [ABSTRACT FROM AUTHOR]

The invalidly published name Massonia sect. Whiteheadia (Harv.) J.C.Manning is validated. [ABSTRACT FROM AUTHOR]

An appreciation of body size allometry is central for understanding insect pollination ecology. A recent model utilises allometric coefficients for five of the seven extant bee families (Apoidea: Anthophila) to include crucial but difficult-to-measure traits, such as proboscis length, in ecological and evolutionary studies. Melittidae were not included although they are important pollinators in South Africa where they comprise an especially rich and morphologically diverse fauna. We measured intertegular distance (correlated with body size) and proboscis length of 179 specimens of 11 species from three genera of Melittidae. With the inclusion of Melittidae, we tested the between family differences in the allometric scaling coefficients. AIC model selection was used to establish which factors provide the best estimate of proboscis length. We explored a hypothesis that has been proposed in the literature, but which has not been tested, whereby body and range sizes of bees are correlated with rainfall regions. We tested this by using body size measurements of 2109 museum specimens from 56 species of Melittidae and applied the model coefficients to estimate proboscis length and foraging distance. Our results from testing differences across bee families show that with the addition of Melittidae, we retained the overall pattern of significant differences in the scaling coefficient among Apoidea, with our model explaining 98% of the variance in species-level means for proboscis length. When testing the relationship between body size and rainfall region we found no relationship for South African Melittidae. Overall, this study has added allometric scaling coefficients for an important bee family and shown the applicability of using these coefficients when linked with museum specimens to test ecological hypothesis.
