species are remarkably diverse in gonopod structure and in some details of the anterior legs. They are tentatively grouped here as a genus because they are very similar in overall morphology, very different from other known Australian dalodesmoids and geographically coherent. The six named species show almost no variation in gonopod form across individual species ranges. A seventh species is known from a single male collected near Strathgordon,
