Australian Arrenurus (Acari, Hydrachnidia) with the description of eleven new species Author Smit, Harry text Zootaxa 2010 2541 1 26 journal article 10.5281/zenodo.196693 bc71468f-9e9f-49e4-b1f1-9f234f7089cf 1175-5326 196693 Arrenurus (Micruracarus) queenslandicus Smit, 1999 Material examined. Victoria. 1/0/0, Glenelg River, at crossing with Henty Highway, 37° 0 6.517 S 142° 11.430 E , 16 March 2008 . Queensland. 9/16/0, Emu Creek at Clancy’s Camping Area, Benarkin State Forest, 26° 58.334 S 152° 0 9.916 E , 3 November 2005 . Distribution. Queensland and reported here for the first time from Victoria. Remarks. As stated before, specimens from Emu Creek show a large variation in size, males are 583–721 long and 494–583 wide, females are 680–940 long and 575–786 wide. Like A. forpicatoides , males have a small triangular extension on the fork-shaped petiole. The status of A. perplexus Smit , a third species with a green coloured idiosoma and a fork-shaped petiole, has to be evaluated given the large variation in size and shape of A. queenslandicus . Unfortunately I have been unable to reexamine A. perplexus .
