Abstract
A reexamination of Martiniella Grabau and Tien, 1931 reveals that the type species, M. nasuta Grabau and Tien, is a nomen nudum. Martiniella is thus restricted to its type species. A new genus, Chuiella gen. nov., is proposed to host the other Chinese species, previously ascribed to Martiniella Grabau and Tien, 1931. In addition, a detailed microfacies, taphonomic and palaeoecological analysis of a fossiliferous bed that contains abundant specimens of Chuiella gen. nov. from the Early Carboniferous Kelitag Formation of the Damusi area in the western Kunlun Mountains, Xinjiang Province, northwest China, reveals that species of Chuiella probably lived in a clean, warm, shallow-water marine, high energy environment. A review of all described species of Chuiella suggests this genus is characteristic of the Tournaisian and restricted to the palaeo-equatorial Eastern Tethyan region. Two species of Chuiella are described, including one new species: Chuiella aitegouensis gen. et sp. nov.
对martinella Grabau和Tien(1931)的重新考察表明，模式种M. nasuta Grabau和Tien是一种雌性裸种。因此，马提尼拉仅限于它的模式种。本文提出了一个新属Chuiella gen. nov.，以取代之前归属于Martiniella Grabau和Tien(1931)的其它中国种。此外，通过对新疆昆仑山西部大木泗地区早石炭世克里塔格组丰富的丘埃拉属化石层的微相、地学和古生态分析，表明丘埃拉属可能生活在清洁、温暖、浅水、高能量的海洋环境中。对所有已描述的Chuiella种的回顾表明，该属是Tournaisian的特征，仅限于古赤道东特提斯地区。报道了两种丘ella，包括一新种:aitegouensis gen. et sp. nov。
