Scheller Häggeboholm, Häggesled, S-53194 Järpås, Sweden. ABSTRACT – In a collection of 4,604 specimens of Pauropoda from the Western Australian jarrah forest 10 genera were represented and 59 species have been identifi ed, 51 of them new species named and described below: four in Pauropus, six in Allopauropus, 33 in Decapauropus, three in Stylopauropoides, and one each in Juxtapauropus, Rabaudauropus, Nesopauropus, Hemipauropus and Antichtopauropus. The genus Amphipauropus is reported from Australia for the fi rst time. Harrison’s collection from 1914 from New South Wales has been restudied. Keys to the families and genera so far known from Australia are given. All valid species known from Australia, 89 at present, have been listed in a systematic section. The main part of the Australian species is not known from elsewhere. KEYWORDS: taxonomy, biodiversity, soil fauna, biogeography, endemism INTRODUCTION further investigation of the taxonomy and distribution of the Pauropoda in Australia. The study is two parted, The Pauropoda is a class within the Myriapoda, and it groups together all the species so far known from are the smallest ones with a body length of 0.5-2 mm Australia into the classifi cation of today but it describes and are whitish-brownish, with bifurcate antennae and also a large collection from a Western Australian survey 8-11 pairs of legs as adults (Scheller 1988, 1990, 2011b). at Dwellingup of soil and litter invertebrates in a jarrah Pauropods seem to be much more diverse than expected, forest (Postle et al. 1991). Thanks to Dr Postle the at present 12 families have been described with 47 pauropods found, all 4604 specimens, were entrusted genera and more than 830 species. They are generally to the author. The identifi cation revealed 59 species, 51 soil-living and widely distributed on all continents. of them new species described below: four in Pauropus, There are two orders, Hexamerocerata and six in Allopauropus, 33 in Decapauropus, three in Tetramerocerata. The former is characterised by Stylopauropoides, and one each in Juxtapauropus, 6-segmented telescopic antennae and 10-11 pairs of Rabaudauropus, Nesopauropus, Hemipauropus and legs as adults, the latter has 4-segmented not telescopic Antichtopauropus. The main part of our present antennae and 8-10 pairs of legs as adults. All Australian knowledge of the Australian Pauropoda comes from pauropods known so far belong to Tetramerocerata. The Dr Postle’s collection and the survey of the Tasmanian Hexamerocerata is tropical and poor in species, only temperate rain forest published a few years ago (Scheller eight known, and has not yet been found in Australia but 2009b, 2011a).

These papers have defi nitely told us that Harrison, the University of Sydney, in 1914 collected the pauropods show a high variability in Australia with and described five species from the Sydney area, many probably endemic species, from Western Australia Lindfi eld and Broken Bay (Harrison 1914). He placed even a new family, Antichtoauropodidae, which might four of them in Pauropodidae (Pauropus amicus, P. be endemic. australis, P. novae-hollandiae, P.

Tiegs described a new species from Broken Bay only. Later he found three more species, Victoria (1943) which he also used for his study “The Pauropus australis, a common species in bark-sheets development and affi nities of the Pauropoda, based at Lindfi eld and Broken Bay, P.
