The present work describes and illustrates in detail the six zoeal stages of Albunea paretii collected from plankton samples on the Amazon continental shelf in Brazil. The morphological characters are compared with those of other known albuneid larvae. As in other albuneids, the zoeae of Albunea paretii have a semi-globose carapace, a long rostral spine and a pair of long posterolateral spines on pereon, as well as three aesthetascs on the antennule of zoea I, a strong antennal spinous process and a convex telson with a stout posterolateral spine. The zoeal morphology of Albunea paretii and other species of the genus differs, especially regarding the unique presence of the posterolateral spine only on the 5th pleonite in zoea I-IV and the absence in later zoeal stages. The differing features of the albuneid subfamilies are in the telson, antenna and maxilla format and number of setae.
本研究详细描述并展示了从巴西亚马逊大陆架浮游生物样本中采集到的帕氏阿布鲁蟹的六个蚤状幼体阶段。将其形态特征与其他已知阿布鲁蟹科幼体的特征进行了比较。与其他阿布鲁蟹科一样，帕氏阿布鲁蟹的蚤状幼体有一个半球形头胸甲、一根长吻棘、一对位于胸部的长后外侧棘，以及在第一期蚤状幼体的小触角上有三根感觉毛、一个强壮的触角棘突和一个带有粗壮后外侧棘的凸起尾节。帕氏阿布鲁蟹与该属其他物种的蚤状幼体形态不同，特别是在第一至四期蚤状幼体中，后外侧棘仅独特地存在于第五腹节上，而在后期蚤状幼体阶段则不存在。阿布鲁蟹亚科不同的特征在于尾节、触角和上颌的形态以及刚毛数量。
