Abstract A new genus and new species of decapod brachyuran, Cuchiadromites jadeae, is recorded and described herein from the Lower Aptian (Early Cretaceous) Patrocinio Formation (Deshayesites forbesi Ammonite Zone) of the coastal cliffs near Cuchia (Cantabria, Spain). Cuchiadromites jadeae gen. et sp. nov., is the fourth species of brachyuran recovered in this locality. The dorsal carapace of the sole specimen preserves sufficient diagnostic characters that allow placement in the family Longodromitidae. The present species exhibits a profuse dorsal ornamentation of fungiform granules that form cauliflower-shaped clusters reminiscent of the ornamentation seen in fossil and extant species of different eubrachyuran families, for instance Parthenopidae or Dairidae, and also in the anomuran families Paguridae or Xylopaguridae, but not described before in podotreme taxa. This could be due to convergence in groups far distant in geological time and systematic placement.

Cuchiadromites jadeae，一种来自坎塔布里亚阿普蒂安（西班牙）的原始螃蟹（甲壳纲：十足目：Podetremata）的新属和种，并对其奇特的表面装饰进行了评论

摘要 本文在库奇亚（西班牙坎塔布里亚）附近的海岸悬崖下阿普特阶（早白垩世）帕特罗西尼奥组（Deshayesites forbesi Ammonite Zone）中记录和描述了十足目短尾龙的一个新属和新种，Cuchiadromites jadeae。Cuchiadromites jadeae gen。等 sp. 11 月，是该地区发现的第四种短尾鱼。唯一标本的背甲保留了足够的诊断特征，允许放置在 Longodromitidae 科中。本种表现出大量的菌状颗粒的背面装饰，形成花椰菜状的簇，让人想起在不同 eubrachyuran 科的化石和现存物种中看到的装饰，例如 Parthenopidae 或 Dairidae，还有在anomuran 科 Paguridae 或 Xylopaguridae，但之前在 podotreme 分类群中没有描述过。这可能是由于在地质时间和系统位置上相距遥远的群体的融合。
