A new species of deep-water oregoniid spider crab of the genus Miers, 1879, is described from the Indian Ocean. The species is distinct in possessing a prominently inflated carapace in which the median parts of the branchial regions almost meet. It can also be distinguished from its closest congeners, (Miers, 1885), (Wood-Mason, in Wood-Mason & Alcock, 1891), and Ahyong & Ng, 2007, in its more elongate and less spinose chelipeds and ambulatory legs, shorter third maxilliped, trapezoidal male pleon and a male first gonopod which is relatively stout with a short subdistal dorsal papilla.
1879年米尔（Miers）所描述的深水奥氏蟹属（Oregoniid）蜘蛛蟹的一个新物种，是从印度洋发现的。该物种的独特之处在于其背甲显著隆起，鳃区的中部几乎相接。它还可以与其最相近的同属物种（米尔，1885年）、（伍德 - 梅森，见于伍德 - 梅森和阿尔科克，1891年）以及阿永（Ahyong）和吴（Ng），2007年）相区分，其螯足和步足更长且棘刺更少，第三颚足较短，雄性腹部呈梯形，雄性第一生殖肢相对粗壮，有一个短的亚远端背乳头。
