Abstract

The complete larval development of Pinnaxodes chilensis (including four zoeal stages and a megalopa stage) is described and illustrated in detail for the first time. The descriptions are based on laboratory-reared larvae obtained from ovigerous females found inside specimens of the sea urchin Loxechinus albus collected in the coast of Valparaíso, Chile. In order to allow the correct differentiation of specimens from plankton samples, the larval stages of P. chilensis are compared with those from other Pinnotheridae species, whose larval development is known for the Chilean continental waters (Calyptraeotheres politus). The morphological characters described for P. chilensis larvae, as well as the comparison with the remaining larval development descriptions available for the genus Pinnaxodes, are used to discuss the heterogeneity within this genus.

摘要

智利囊对虾的完整幼体发育（包括四个幼体阶段和一个大眼幼体阶段）首次被详细描述和说明。这些描述是基于从智利瓦尔帕莱索海岸采集的有卵的白棘海胆标本中发现的繁殖雌虾，在实验室中培养的幼虫得出的。为了能够正确区分浮游生物样本中的标本，将智利囊对虾的幼虫阶段与其他智利大陆水域已知的囊对虾科物种的幼虫阶段进行比较（Calyptraeotheres politus）。为智利囊对虾幼虫描述的形态特征，以及与可用于该属的其余幼虫发育描述的比较，用于讨论该属内的异质性。
