The Genus Underwoodisaurus


  The taxonomic status of the genus Underwoodisaurus has always been disputed. In 1823, Bory de Saint-Vincent assigned the species milii to the genus Phyllurus. Afterwards, repeated attempts were made to establish this genus as an independent taxonomix unit.
  The name Underwoodisaurus was first mentioned in DAS TIERREICH in 1965, referring to a subgenus of Gymnodactylus (milii). It was only in 1970 that Bustard adopted it as a true generic name for Underwoodisaurus milii. Subsequently, the status of this genus was subjected to varous changes until Bauer assignated it to the genus Nephrurus in 1990. 
   I do not believe that this species really belongs to the genus Nephrurus; conseqeuntly i keep using the generic name Underwoodisaurus. Meanwhile, diverse forms of varying size and appearance have been discovered within the species U. milii , and it is very likely that they will beb recognized as independent species (or subspecies) in near future.
  Whereas U. sphyrurus is limited to a small region on Australia's eastern coast,  theh above-mentioned forms of  U. milii  inhabit the southern part of the continent (execpt the extreme South). U. sphyrurus lives in a rather humid region whereas U. milii prefers arid and partially rock habitats. Either species is known to bury its soft-shelled eggs in moist substrates.
