Euastacus morgani sp. n., is described from a highland, rainforest site in Bindarri National Park, in eastern New South Wales, Australia. Euastacus morgani is found living sympatrically with two more common species, Euastacus dangadi Morgan, 1997 and Euastacus neohirsutus Riek, 1956. Systematically, the species belongs in the 'simplex' complex of the genus that includes Euastacus simplex Riek, 1956, Euastacus clarkae Morgan, 1997, Euastacus maccai McCormack and Coughran 2008 and E. morgani. This new species differs from its nearest congenor, Euastacus simplex, in having three mesial carpal spines. A key to the 'simplex' complex is presented.
新种摩根尤氏螯虾(Euastacus morgani sp. n.)是在澳大利亚新南威尔士州东部宾达里国家公园的一个高地雨林地区发现的。摩根尤氏螯虾与另外两种常见物种——1997年发现的丹加迪尤氏螯虾(Euastacus dangadi Morgan)和1956年发现的新多毛尤氏螯虾(Euastacus neohirsutus Riek)——同域分布。在分类学上,该物种属于该属的“单形”复合体,其中包括1956年发现的单形尤氏螯虾(Euastacus simplex Riek)、1997年发现的克拉克尤氏螯虾(Euastacus clarkae Morgan)、2008年发现的麦凯尤氏螯虾(Euastacus maccai McCormack and Coughran)以及摩根尤氏螯虾。这个新物种与其最接近的同属物种单形尤氏螯虾的区别在于,它有三根腕骨中刺。文中还给出了“单形”复合体的检索表。
