摘要

对西班牙中部中奥陶世奥陶系重长机会岩标本的重新研究表明，calx inornatus MELENDEZ物种有四个ambulacra，每个都有两个相等的面，一个椭圆形的水孔和光滑的鞘面。相比之下，萼萼的模式种有四个侧壁，每个侧壁在生长过程中按顺时针方向增加了四个面，一个三叶状的水孔和一个带刺板的膜。其他有四个足部的马兜铃属每足部有一个关节面。' calx ' inornatus不同于所有其他马兜铃属和保证一个新的通用名称，我们建议Enodicalix。

Enodicalix (Diploporita, Aristocystitidae): A new echinoderm genus from the Middle Ordovician of Spain

Restudy of an Ordovician diploporite specimen from the Middle Ordovician of central Spain reveals that the species ‘Calix’ inornatus MELENDEZ has four ambulacra, each with two equal facets, an oval hydropore and a smooth thecal surface. In contrast, the type species of Calix has four ambulacra, each with four facets added in a clockwise direction during growth, a trilobed hydropore, and a theca with spiny plates. Other aristocystitid genera with four ambulacra have one facet per ambulacrum. ‘Calix’ inornatus differs from all other aristocystitid genera and warrants a new generic name, for which we propose Enodicalix .
