“…Specimens were mostly collected by sifting leaf litter or by direct search under stones and logs. While litter sifting has been a preferred collecting method yielding large numbers of specimens, direct search worked better in most South African localities; direct collecting was also used for the cave species Speleosiro argasiformis (see Giribet et al ., ).…”

We evaluate the phylogenetic and biogeographical relationships of the members of the family Pettalidae (Opiliones, Cyphophthalmi), a textbook example of an ancient temperate Gondwanan taxon, by means of DNA sequence data from four markers. Taxon sampling is optimized to cover more than 70% of the described species in the family, with 117 ingroup specimens included in the analyses. The data were submitted to diverse analytical treatments, including static and dynamic homology, untrimmed and trimmed alignments, and a variety of optimality criteria including parsimony and maximum-likelihood (traditional search and Bayesian). All analyses found strong support for the monophyly of the family Pettalidae and of all its genera, with the exception of Speleosiro, which is nested within Purcellia. However, the relationships among genera are poorly resolved, with the exceptions of a first split between the South African genus Parapurcellia and the remaining species, and, less supported, a possible relationship between Chileogovea and the other South African genus Purcellia. The diversification of most genera is Mesozoic, and of the three New Zealand genera, two show evidence of constant diversification through time, contradicting scenarios of total submersion of New Zealand during the Oligocene drowning episode. The genera Karripurcellia from Western Australia and Neopurcellia from the Australian plate of New Zealand show a pattern typical of relicts, with ancient origin, depauperate extant diversity and recent diversification. The following taxonomic actions are taken: Milipurcellia Karaman, 2012 is synonymized with Karripurcellia Giribet, 2003 syn. nov.; Speleosiro Lawrence, 1931 is synonymised with Purcellia Hansen & Sørensen, 1904 syn. nov. The following new combinations are proposed: Parapurcellia transvaalica (Lawrence, 1963) comb. nov.; Purcellia argasiformis (Lawrence, 1931) comb. nov.

The Wynberg Cave System, the most important site for cave fauna in South Africa at risk

The Wynberg Cave System, located on the Cape Peninsula, represents one of the most significant sites of cave fauna in southern Africa. However, the continuous increase in cave visitation is severely impacting the system as evidenced by graffiti, the trampling and destruction of cave habitats and even a reduction in the sizes of bat colonies. In October 2019, the Wynberg Cave System was visited by a group of scientist, who discovered unregistered troglomorphic species. This, subsequently increased the number of troglobites occurring in the system to 19, which likely means that this system has the potential to become the first hotspot of subterranean biodiversity in Africa. Protecting the Wynberg Cave System is therefore of great importance. Here, we propose short and long-term strategies that include educating local communities on the importance of conserving caves and installing gated entrances.
