Introduction

Shield or tadpole shrimps are a distinctive goup of large branchiopods, and are characterised by a dorsal shield-shaped carapace partially covering a multisegmented body. The last few to many segments are limbless and the last one bears a pair of long caudal rami. Many species and varieties occur worldwide and are contained in the one family within two genera, Triops and Lepidurus (Longhurst 1955), though Murugan et al. (2002) suggest that material presently identified as Triops cancriformis could represent a third genus. Both described genera are represented by one species each in Australia (Williams 1968). Lepidurus is a well supported monophyletic unit, while Triops is polyphyletic, embodying very divergent taxa (Mantovani et al. 2004),
