The majority of cornuproetine taxa known from articulated specimens have ten thoracic segments. Here we record rare, well-preserved specimens with nine segments in the Early and Middle Devonian of Morocco, Germany and the Czech Republic. These encompass the genera Lepidoproetus Erben, Sculptoproetus Erben, Macroblepharum Alberti, Koneprusites Přibyl, Paralepidoproetus Alberti, Timsaloproetus Gibb and Chatterton and Hollandiella gen. nov. Large holaspides of these trilobites are often comparatively small and bear dorsal sculpture consisting of terrace lines in a fingerprint-like configuration, small granules, or a mixture of these features. The holotype of Sculptoproetus sculptus (Barrande) and the lectotype of Lepidoproetus lepidus (Barrande), the type species of these genera, are refigured. Additional topotypical specimens of S. sculptus are illustrated; these provide new insights into the morphology of this species, leading to the putative synonymy of Macroblepharum with Sculptoproetus. The following new cornuproetine taxa are described: Hollandiella curvirostris gen. et sp. nov., Hollandiella lebruni gen. et sp. nov., Hollandiella verecunda gen. et sp. nov., Koneprusites oresibios sp. nov., Lepidoproetus arenicolus sp. nov., Sculptoproetus raki sp. nov., Timsaloproetus weddigei sp. nov., Timsaloproetus gibbae sp. nov., Timsaloproetus pulchistriatus pulchistriatus ssp. nov. and Timsaloproetus pulchistriatus repens ssp. nov. Timsaloproetus haasi is recorded from several localities in Morocco. Additionally, Tafilaltaspis rufa sp. nov. is proposed as a new species of the nine-segmented eremiproetine Tafilaltaspis, which was traditionally classified as a cornuproetine genus.

来自摩洛哥泥盆纪，德国和捷克共和国的具有9个胸腔节段的Cornuproetine（proetide）三叶虫

从关节标本中已知的大多数角膜上皮类群有十个胸段。在这里，我们在摩洛哥，德国和捷克共和国的泥盆纪早期和中期记录了保存完好的稀有标本，共分为九段。这些涵盖属Lepidoproetus厄尔本，Sculptoproetus厄尔本，Macroblepharum阿尔贝蒂，Koneprusites Přibyl，Paralepidoproetus阿尔贝蒂，Timsaloproetus吉布和查特和Hollandiella根。十一月 这些三叶虫的大holaspides通常相对较小，并具有背侧雕塑，其由呈指纹状构形的梯田线，小颗粒或这些特征的混合物组成。的原型重新定义了Sculptoproetus sculptus（Barrande）和Lepidoproetus lepidus（Barrande）的选型。还显示了S. sculptus的其他典型标本。这些为该物种的形态学提供了新的见解，从而导致了Macroblepharum与Sculptoproetus的假定同义词。以下新cornuproetine类群进行了说明：Hollandiella curvirostris根。等。十一月，霍尼迪菌lebruni gen。等。十一月，荷兰荷花藻。等。十一月，Koneprusites oresibios sp.。十一月，Lepidoproetus arenicolus sp.。十一月Sculptoproetus raki sp。十一月，Timsaloproetus weddigei sp。十一月，Timsaloproetus gibbae sp。十一月，Timsaloproetus pulchistriatus pulchistriatus ssp。十一月 和Timsaloproetus pulchistriatus ssp。十一月 Timsaloproetus haasi在摩洛哥的多个地方都有记录。此外，Tafilaltaspis rufa sp。十一月 有人建议将其作为九节段的艾美洛太林Tafilaltaspis的新物种，传统上将其分类为Cornuproetine属。
