São Pedro, São Paulo (Brazil) Modern taxonomic studies of 5-10 August 2007 Australian Salticidae emerged 35 years ago. Proszynski (1971) catalogued http://www.ib.usp.br/~ricrocha/ISA17/ISA.htm salticid type material from major collections worldwide and verified the generic status of some of the species. The same author produced a two-volume atlas of diagnostic drawings (Proszynski 1984, 1987) and a catalogue (Proszynski 1990), all three of them eventually amalgamated into an online world catalogue of the Salticidae (Proszynski 2003). Davies and Zabka (1989) published a key to the 50 Australian genera of Salticidae with diagnoses and remarks on some species of uncertain taxonomic status. The interactive CD- Rom Spiders of Australia by Raven et al. (2002) was one of the latest contributions to include jumping spiders. Jumping spider (Araneae, In the last 20 years nearly 140 new Salticidae) taxonomy and species and 14 genera were described biogeography in Australia: (see Richardson and Zabka 2003; current state and future bibliography below), most of them by myself (9 genera and 109 species) and by prospects F.R.

Koch for example Holoplatys (7 and 37 species (1871-1881) and Keyserling (1881-1890) respectively) (Zabka 1991). Similar Australasian Arachnology No. 76 Page 5 numbers were confirmed for the Astieae salticid faunas worldwide.

Taxonomic research on Salticidae Not surprisingly, the richest taxonomic suffers from difficulties in relation to the data are available for areas near major uniformity and simplicity of the genitalia centres of arachnological research and and large intraspecific variation in those areas subject to their research morphological characters. Wayne activities (Richardson et al. 2006). In Maddison (University of British Columbia, contrast, some inland areas and most Vancouver) and co-workers showed that parts of topical Western Australia and the some systematic problems, mostly at the Northern Territory are still extremely family and genus level, could be solved poorly studied. employing molecular techniques (Maddison 1996, Hedin and Maddison Few scientific institutions currently 2001, Maddison and Hedin 2003). conduct taxonomic projects on Australian Salticidae.

(2006), while Harvey et al. (2000) and Churchill (1996, 1999) presented interesting contributions to the ecology and regional biogeography of spiders (including Salticidae) in Australia. Due to its long-term isolation and evolution of unique climates and biota, the Australian salticid fauna is highly diverse and many taxa represent endemic “prisoners” of the continent with only limited abilities to colonise more or less distant areas such as New Guinea, New Caledonia, Fiji or New Zealand (Zabka 1993a, Zabka et al. 2002, Patoleta 2002). No significant links to other southern (post-Gondwanan) faunas have so far been established, although very little research has been conducted on the fauna of Nothofagus and other wet temperate forest, especially in southern parts of the continent and Tasmania.
