“…Lehtinen (1996: 409) has already referred to the group as Trachelidae, but without any comment of justification; hence, it is unclear whether he really meant to propose it as a new family group, or he just committed a lapsus. Platnick and Ewing (1995) noted that the absence of leg spines and the male cusples were not universal in trachelines, and Haddad (2006) described Spinotrachelas capensis, a tracheline genus with many spines on their anterior tibiae, plus cusples on the metatarsus, and later (Haddad and Lyle, 2008) described Poachelas, including species with heavily spinose forelegs, that could be absent in females of some species. They reasonably suggested that Spinotrachelas and Poachelas, by their abundant spines, could be basal trachelines.…”

“…225, table 33). Haddad and Lyle (2008) and Haddad (2006) suggested that the tracheline genera Poachelas and Spinotrachelas might be the most basal members of the family because they retained fully developed leg spines. They also suggested that genera such as Fuchiba and Fuchibotulus, which lack both spines and cusps even in males, should be among the most-derived trachelids.…”

“…often provides considerable numbers of these spiders. Initially, Poachelas striatus Haddad & Lyle was described from only three localities in the central Free State (Haddad & Lyle, 2008), but hand collecting in grass tussocks elsewhere in the country resulted in many additional records from the Free State, as well as the first records from the Northern Cape, Eastern Cape and Mpumalanga, extending the distribution of the species to more than 900 km (Haddad, 2010).…”

Biodiversity is one of the most important concepts in contemporary biology, with a broad range of applications. In November 1995, South Africa ratified the Convention on Biological Diversity (CBD). Signatories are obligated to develop a strategic plan for the conservation and sustainable use of biodiversity. To meet the requirements of the CBD, the South African National Survey of Arachnida (SANSA) was initiated in 1997. This national project has several aims: to document and describe the arachnid fauna of South Africa; to consolidate all the available data on South African arachnids into one relational database and to make this biodiversity information available to science; and to address issues concerning their conservation and sustainable use. Extensive sampling took place and the SANSA database contains a wealth of biodiversity data that are used to provide answers to ecological questions. Presently 71 spider families, 471 genera and 2170 species are known from South Africa, representing approximately 4.8% of the world fauna. This paper presents the current state of spider biodiversity information and how it is managed. It demonstrates the importance of running a national inventory; emphasises the significance of using a good database application; and the importance of capacity development to improve the quality and integration of biodiversity information. Further, it shows the role SANSA has played in unifying and strengthening arachnid research, with the major thrust to discover the spider diversity in South Africa. We discuss the present status of knowledge, constraints to improving this, and the future directions for research. SANSA has provided the foundations for a more integrative approach to spider diversity research. Future research should build on this legacy by linking taxonomic diversity with that of functional diversity, predicting the response of this diversity to global change drivers. Functional approaches will link these studies to ecosystem processes. Global collaborative studies at several sites following standardised sampling protocols and focused research questions would add value to the SANSA collection and the importance of spiders for the health of ecosystems.

“…Although most genera in this subfamily resemble ants, Copa species have cryptic colouration and closely resemble wolf spiders of the family Lycosidae (Figs 1–6), a characteristic shared with Echinax and two undescribed lycosiform castianeirine genera (Haddad 2012a, b, in prep.). Copa are very common spiders in the leaf litter of various habitats and are predominantly ground-living, occurring widely in savanna woodlands but also occasionally in forests, where they are well camouflaged.…”

“…Prior to this revision, seven species and one subspecies of Copa were known from the Afrotropical Region (Dippenaar-Schoeman and Jocqué 1997), of which one described by Simon (1909) has been transferred to Echinax (Haddad 2012a). Another species, described by Strand (1916), will be transferred to a new castianeirine genus (Haddad 2012b in prep. ).…”

A revision of the continental species of Copa Simon, 1885 (Araneae, Corinnidae) in the Afrotropical Region

The cryptic ground-dwelling castianeirine genus Copa Simon, 1885 (Araneae: Corinnidae) is revised in the continental Afrotropical Region. The type species of the genus, Copa flavoplumosa Simon, 1885, is redescribed and considered a senior synonym of Copa benina Strand, 1916 syn. n. and Copa benina nigra Lessert, 1933 syn. n. It is widespread throughout the Afrotropical Region but has not been introduced to any of the associated regional islands. A new species, Copa kei sp. n., is described from South Africa. Copa agelenina Simon, 1910, originally described from a subadult female from southern Botswana, is considered a nomen dubium. Copa flavoplumosa is a characteristic species of leaf litter spider assemblages and is particularly prevalent in savanna habitats on the continent, but also occurs in various forest types, grasslands, fynbos and semi-arid Nama Karoo habitats. In contrast, Copa kei sp. n. has only been recorded from Afromontane and coastal forests in south-eastern South Africa.
