FIGURE 6. Map of the Breede River system in the south-western Cape Floristic Region of South Africa showing the distribution of Pseudobarbus skeltoni sp. nov. Individuals of this species were previously collected from the Wit River in 1975, but have not been found in recent surveys. The upper Riviersonderend is the type locality.

Note the position of mouth, and a large eye relative to head length in P. burchelli and P. burgi. Also note the clear differences in tubercle expression of mature males of the three species.

Both P. burgi and P. burchelli have retracted lips exposing a cartilaginous plate, but lips are unretracted in P. skeltoni and cartilaginous plate is absent (based on seven specimens examined).

The cluster of P. skeltoni sp. nov include 12 recently collected specimens from the Riviersonderend and Krom Rivers as well as 11 specimens from two samples collected in the Wit River (see text for details).

FIGURE 1. Bayesian phylogram with Bayesian posterior probabilities, showing the genetic distance between Pseudobarbus skeltoni sp. nov. compared to all other Pseudobarbus lineages. Although phylogenetic relationships among Pseudobarbus lineages should be based on Swartz et al. (2009) due to more data that were analysed, it is clear from the present study that P. skeltoni is closely related to Pseudobarbus lineages that have two distinct pairs of barbels. More genes will have to be analysed to resolve the phylogenetic relationships within this group.

Distribution. Widespread in the C and W regions of S Africa, reaching to about 15° N in SW Angola. Occupies mainly arid and semi-arid areas, but also occurs in regions with higher precipitation and denser vegetation, such as the fynbos biome of South Africa's Western Cape Province. Cape Foxes have expanded their range over recent decades to the SW, where the species reaches the Atlantic and Indian Ocean coastlines. May occur in SW Swaziland, and possibly also in Lesotho. in Canidae

Reduced visitation to buzz-pollinated Cyanella hyacinthoides in the presence of other pollen sources in the hyperdiverse Cape Floristic Region

<p>Many plant species have floral morphologies that restrict access to floral resources, such as pollen or nectar, and only a subset of floral visitors can perform the handling behaviours required to extract restricted resources. Due to the time and energy required to extract resources from morphologically complex flowers, these plant species potentially compete for pollinators with co-flowering plants that have more easily accessible resources. A widespread floral mechanism restricting access to pollen is the presence of tubular anthers that open through small pores or slits (poricidal anthers). Some bees have evolved the capacity to remove pollen from poricidal anthers using vibrations, giving rise to the phenomenon of buzz-pollination. These bee vibrations that are produced for pollen extraction are presumably energetically costly, and to date, few studies have investigated whether buzz-pollinated flowers may be at a disadvantage when competing for pollinators' attention with plant species that present unrestricted pollen resources. Here, we studied Cyanella hyacinthoides (Tecophilaeaceae), a geophyte with poricidal anthers in the hyperdiverse Cape Floristic Region of South Africa, to assess how the composition and relative abundance of flowers with easily accessible pollen affect bee visitation to a buzz-pollinated plant. We found that the number of pollinator species was not influenced by community composition. However, visitation rates to C. hyacinthoides were reduced when the relative abundances of flowers with more accessible resources were high. Visitation rates were strongly associated with petal colour, showing that flower colour is important in mediating these interactions. We conclude that buzz-pollinated plants might be at a competitive disadvantage when many easily accessible pollen sources are available, particularly when competitor species share its floral signals.</p>
