摘要

鞭蝎化石(Thelyphonida)在巴西下白垩统Araripe盆地克拉托组地层中极为罕见。到目前为止，在这个单元中只描述了四个鞭蝎标本。所有的标本都被归为Mesoproctus Dunlop属，只有一个种被正式提出，M. rowlandi Dunlop。在中生代，除了克拉托组，鞭蝎只在缅甸北部胡康河谷的琥珀沉积物中记录到两种。在这种情况下，每一个中生代鞭蝎的新发现都非常重要。此外，我们提出了从化石鞭蝎书肺的第一个记录的例子。在这里，我们介绍并说明了在克拉托地层中发现的一种新的鞭蝎标本。关键词:爪蟾，尾猿，中直肠肌，Aptian, Lagerstätten

A new specimen of whip scorpion (Arachnida; Thelyphonida) from the Crato Formation, Lower Cretaceous of Brazil

Fossil whip scorpions (Thelyphonida) are extremely rare in the Crato Formation strata, Araripe Basin, Lower Cretaceous (Aptian) of Brazil. Only four specimens of whip scorpions have been described in this unit so far. All specimens have been assigned to the genus Mesoproctus Dunlop and only one species has been formally proposed, M. rowlandi Dunlop. For Mesozoic times, apart from Crato Formation, whip scorpions are only documented by two species in the amber deposits of the Hukawng Valley, northern Myanmar. In this scenario, each new discovery of Mesozoic whip scorpion is highly important. In addition, we present the first documented example of book lungs from a fossil whip scorpion. Here, we present and illustrate a new specimen of whip scorpion found in the Crato strata. Keywords: Crato arachnofauna, Uropypi, Mesoproctus, Aptian, Lagerstätten.
