and are both strongly supported, monophyletic limnadiid lineages based on molecular studies. However, defining the two taxa morphologically relies on the presence/absence of a subcercopodal spiniform projection; otherwise there is considerable overlap and confusion in morphological characters between the two taxa. The most discriminatory of these characters are examined here and applied to Australasian species. As a result, five species are transferred to . These characters are then applied to world species and other limnadiid genera which share key features with .
基于分子研究,二者均得到有力支持,属于单系的鲎虫谱系。然而,从形态学上定义这两个分类单元依赖于亚尾足刺状突起的有无;否则,这两个分类单元在形态特征上存在相当大的重叠和混淆。本文研究了这些最具区分性的特征,并将其应用于澳大拉西亚地区的物种。结果,五个物种被转移到了[具体分类单元]。然后,这些特征被应用于世界范围内的[具体分类单元]物种以及与[具体分类单元]具有关键特征相同的其他鲎虫属。
