Camptochaete leichhardtii

This track connects eastern Australia with the New Caledonia-Vanuatu area. It sometimes also involves presence on Lord Howe and Norfolk Islands. Camptochaete curvata is endemic in central eastern Australia and Camptochaete leichhardtii has a similar distribution there and is also present in Vanuatu. Variations on this pattern are provided by Hypopterygium discolor (central eastern Australia and northern New Zealand) and Braithwaitea sulcata (eastern Australia, Lord Howe... 

By mapping the distributions of individual species it is apparent that different species have distributions that highlight different biological relations between areas within Australasia. The addition of species reinforces the pattern by repeating distributions wholly or partly, or by the patterns marking boundaries for taxa. For example. Track 1 is a southern boundary for several species examined here and is also the distribution of other species (e.g., Camptochaete subporotrichoides). Similarly, Track 3 (central eastern Australia-New Caledonia) corresponds to the distribution of some species (Camptochaete leichhardtii). It is also a boundary within Camptochaete, and a northern or southern boundary for many other species. As noted above, the eastern end of this track is known as the Macpherson-Macleay Overlap, an important locality in the region. 

Sect. Camptochaete has a southern Tasman Sea distribution, with four of its live species present in mainland New Zealand, and two of these also in south-eastern Austraha. The distribution of the remaining species in sect. Camptochaete, C. leichhardtii corresponds to the overlap between the two sections south-east Austraha, southern Queensland to Victoria, and Vanuatu.
