Abstract

The first fossil Solenoceridae found from the Cretaceous (Aptian-Albian) is described in the Araripe Sedimentary basin, Priorhyncha feitosai n. gen. n. sp. The material was collected in the strata of the Romualdo Formation, municipality of Trindade, Pernambuco. Characters that permit placement of the new species in Solenoceridae are: a short, dorsally serrated rostrum; a marked cervical groove; and the presence of an antennal spine. Those characters are also diagnostic for Priorhyncha feitosai n. gen. n. sp. when compared to the other Dendrobranchiata shrimp described from this basin.

摘要

在阿雷里佩沉积盆地发现的首个白垩纪（阿普特阶-阿尔比阶）的长额虾科化石——费托萨原吻虾新属新种被描述。该材料采自伯南布哥州特林达德市罗穆阿尔多组地层。能将这个新物种归入长额虾科的特征有：短且背部有锯齿的吻部；明显的颈沟；以及触角刺的存在。与该盆地描述的其他枝鳃亚目虾类相比，这些特征也是费托萨原吻虾新属新种的鉴别特征。
