    Abstract A new species of Setanodosa, S. jacquesi sp. nov. is described from the Western Cape (South Africa). It differs from other species of the genus by its unique shocking red pigmentation, the number of vesicles in the post antennal organ, and the number of clavate tenent hairs on the tibiotarsi. A comparative table of the world Setanodosa and a key of Brachystomellidae species known from South Africa are provided. DNA barcoding results are provided for several Brachystomellidae species from South Africa, Australia and the sub-Antarctic to support our findings. It shows that a species provisionally identified as Brachystomella cf. platensis is unambiguously present in both South Africa and Australia.

    Abstract Three new species, Parisotoma ruseki sp. nov., P. yehlathi sp. nov., and Folsomotoma amyliuae sp. nov. are described from South Africa. Parisotoma ruseki sp. nov. is characterized by four posterior s-chaetae on each side of the three first abdominal segments and seven posterior chaetae on dens, Parisotoma yehlathi sp. nov. by five s-chaetae and eight chaetae on dens, respectively. All s-chaetae on the body of Folsomotoma amyliuae sp. nov. are short, unlike its congeners. The genera Folsomotoma and Halisotoma are recorded for the first time in South Africa.

    Abstract The genus Bagnallella Salmon is restored and given a diagnosis. It takes an intermediate position between Proisotoma Börner and Cryptopygus Willem complexes and is characterized by the separation of the two last abdominal segments (like in Proisotoma) and 3 and 5 s-chaetae on the fourth and fifth abdominal segments (like in Cryptopygus and its allies). A list of and key to species belonging to Bagnallella is given. Bagnallella biseta comb. nov., B. dubia comb. nov., B. sedecimoculata comb. nov., and B. tenella comb. nov. are commented and redescribed. Morphology of Bagnallella davidi (Barra), comb. nov. is described from the specimens from South Africa. So far B. davidi appears to be a complex of forms differing in size of the furca and macrochaetae. Two types of strongly modified males were found and described. Antennae, ventral side of abdomen, posterior edge of abdominal tergites, and mandibles are affected with epitoky. The nature of the discovered strong polymorphism is unclear.

    Abstract Landscape transformation for agriculture threatens global biodiversity through simplification of ecosystems. We determine whether large-scale timber plantations contribute to biotic homogenization of soil biodiversity relative to remnant natural vegetation. We examined ant and springtail alpha- and beta-diversity, and assemblage composition, among biotopes in two different climatic and soil regions in a subtropical area of South Africa. Surprisingly, we observed equally high levels of alpha- and beta-diversity in plantations (Eucalyptus and Pinus) as in natural biotopes (indigenous forest and grassland) for both taxa in both regions, except in the inland sites where ant species richness was highest in grassland. Furthermore, beta-diversity in all biotopes was mainly due to species replacement rather than nestedness. The high diversity in plantations is likely due to high environmental variation among plantation sites, likely providing diverse niche opportunities across plantations. A possible mechanism for the large proportion of shared species between natural areas and plantations is colonization of arthropods from natural areas into plantations and/or source populations surviving harvesting and tree planting and then their populations growing during long periods of tree maturation. Plantations and natural areas supported complementary assemblages, which builds on the idea that remnant natural vegetation in production landscapes is essential for conserving not only unique aboveground biodiversity, but also unique belowground biodiversity. Furthermore, timber plantations do not homogenize soil arthropod taxonomic diversity as expected. This contrasts with global trends on biodiversity response to land-use change and emphasizes that conservation principles for soil biodiversity may differ from those aimed at aboveground biodiversity.

    Abstract Species of the genera of the Cryptopygus complex in South Africa are morphologically revised. Five new species of the genus Cryptopygus Willem, 1902 s. s. and one new species of the genus Isotominella Delamare Deboutteville, 1948 are described. Cryptopygus abulbus sp. nov. and C. bulbus sp. nov. have only one chaeta on the anterior side of dens and no chaetae on the anterior side of manubrium, the latter species being characterized by the presence of a bulb at apex of antennae; C. inflatus sp. nov. shows a rare combination of eight ocelli on each side of the head with a tridentate mucro; C. longisensillus sp. nov. has five long s-chaetae on the fifth abdominal segment; C. postantennalis sp. nov. is unique by having a very long and slender postantennal organ with strong inner denticles; Isotominella laterochaeta sp. nov. is the second member of the genus and differs from the type species by many more anterior chaetae on the manubrium and the presence of chaetae on ventral side of metathorax. The genera are discussed and a key to all species of the Cryptopygus complex recorded in South Africa is given. The focus is on the Western Cape Province where the complex is the most diverse and sampling more complete than in other provinces of South Africa.

    Abstract Trait-environment interactions have contributed to the remarkable plant radiations in the Cape Floristic Region (CFR) of southern Africa. Whether such interactions have also resulted in the diversification of the invertebrate fauna, independently of direct associations with plants is, however, not clear. One candidate where this may be the case is the unusually diverse Collembola genus Seira. Including 89 species in the CFR, many of which are localised habitat specialists, this genus includes many species inhabiting the warm, dry fynbos shrubland-a habitat atypical of usually desiccation-sensitive Collembola. Here, we investigate whether desiccation tolerance may have contributed to the considerable diversity of Seira in the CFR. First, we demonstrate, by measuring vapour pressure deficits (VPD) of the species' microhabitats (fynbos shrubland and moister Afrotemperate Forests), that the fynbos shrublands are dry environments (mean ± S.E. maximum VPD 5.2 ± 0.1 kPa) compared with the Afrotemperate Forest patches (0.3 ± 0.02 kPa) during the summer activity period of Seira. Then we show that Seira species living in these shrublands are more desiccation tolerant (mean ± S.E. survival time at 76% relative humidity: 74.3 ± 3.3 h) than their congeners in the cooler, moister Afrotemperate Forests (34.3 ± 2.8 h), and compared with Collembola species globally (3.7 ± 0.2 h). These results, and a previous demonstration of pronounced thermal tolerance in the fynbos shrubland species, suggest that the diversity of Seira in the CFR is at least partly due to pronounced desiccation and thermal tolerance, which has enabled species in the genus to exploit the hot and dry habitats of the CFR.

    Abstract Much interest exists in the extent to which constant versus fluctuating temperatures affect thermal performance traits and their phenotypic plasticity. Theory suggests that effects should vary with temperature, being especially pronounced at more extreme low (because of thermal respite) and high (because of Jensen's inequality) temperatures. Here we tested this idea by examining the effects of constant temperatures (10 to 30 °C in 5 °C increments) and fluctuating temperatures (means equal to the constant temperatures, but with fluctuations of ±5 °C) temperatures on the adult (F2) phenotypic plasticity of three thermal performance traits – critical thermal minimum (CTₘᵢₙ), critical thermal maximum (CTₘₐₓ), and upper lethal temperature (ULT₅₀) in ten species of springtails (Collembola) from three families (Isotomidae 7 spp.; Entomobryidae 2 spp.; Onychiuridae 1 sp.). The lowest mean CTₘᵢₙ value recorded here was -3.56 ± 1.0 °C for Paristoma notabilis and the highest mean CTₘₐₓ was 43.1 ± 0.8 °C for Hemisotoma thermophila. The Acclimation Response Ratio for CTₘᵢₙ was on average 0.12 °C/°C (range: 0.04 to 0.21 °C/°C), but was much lower for CTₘₐₓ (mean: 0.017 °C/°C, range: -0.015 to 0.047 °C/°C) and lower also for ULT₅₀ (mean: 0.05 °C/°C, range: -0.007 to 0.14 °C/°C). Fluctuating versus constant temperatures typically had little effect on adult phenotypic plasticity, with effect sizes either no different from zero, or inconsistent in the direction of difference. Previous work assessing adult phenotypic plasticity of these thermal performance traits across a range of constant temperatures can thus be applied to a broader range of circumstances in springtails.
