Abstract

The complete larval development of Petrolisthes tuberculatus (including two zoeal stages and the megalopa) is described and illustrated in detail for the first time, based on laboratory-reared material. In order to allow the differentiation of specimens from plankton samples, the larval stages of P. tuberculatus are compared with those known for other porcellanid crabs from Chilean waters (Allopetrolisthes angulosus, Petrolisthes granulosus, P. laevigatus and P. violaceus). As expected, this comparison lead to the inclusion of P. tuberculatus within the "sección Porcellanina" together with the other Chilean species of porcellanids.

摘要

基于实验室饲养的材料，首次详细描述并说明了瘤突瓷蟹（Petrolisthes tuberculatus）完整的幼体发育过程（包括两个蚤状幼体阶段和大眼幼体）。为了能够区分浮游生物样本中的标本，将瘤突瓷蟹的幼体阶段与智利海域其他瓷蟹科螃蟹（角突拟瓷蟹（Allopetrolisthes angulosus）、颗粒瓷蟹（Petrolisthes granulosus）、光滑瓷蟹（P. laevigatus）和紫瓷蟹（P. violaceus））已知的幼体阶段进行了比较。不出所料，通过这种比较，瘤突瓷蟹与其他智利瓷蟹科物种一起被归入“Porcellanina组”。
