Revisions of Australian ground-hunting spiders VI: five new stripe-less miturgid genera and 48 new species (Miturgidae: Miturginae) Raven, Robert J.

The diagnostic feature of the median apophysis of  M. echinoides  sp. nov.is the median apophysis with an extensive unsclerotised area that projects as a rounded shelf retrolaterally ( Fig. 31a, arrow). Epigyne with median septum short and wide, anterior septum, and procurved ridges with deeper median zone.   Etymology.The species epithet refers to the spinose form of the cymbium.   Type material.  Western Australia: male holotype, Barrow Island, Bandicoot Bay, 20°52 115°20,  4 Nov –3 Dec 1993. M.S.
