ABSTRACT

Polyclads are marine free-living Platyhelminthes, generally disregarded in marine environmental assessments. Here, Phrikoceros inca (Cotylea, Pseudocerotidae), identified on the basis of external features such as its ear-like, held-erected pseudotentacles, number and position of pseudotentacular eyes, circular-like cerebral eyespot, ruffled-shaped body and coloration patterns, was recorded for Peru for the first time. This finding, which occurred in Pucusana beach, near Lima, on the central coast of Peru, extends the distribution of P. inca ~1700 km north, thus becoming the northernmost record of this polyclad species. Also, the formally described species of polyclads from Peru are reviewed and listed.

秘鲁中部海岸 Phrikoceros inca(Polycladida,Cotylea)的新记录,以及对秘鲁水域已知的 polyclads 的回顾

摘要

Polyclads 是海洋自由生活的扁形动物,在海洋环境评估中通常被忽视。在这里,Phrikoceros inca(Cotylea,Pseudocerotidae)根据外部特征进行识别,例如它的耳朵状、竖立的假触手、假触手眼的数量和位置、圆形大脑眼点、荷叶边形身体和着色模式,首次为秘鲁录制。这一发现发生在秘鲁中部海岸利马附近的 Pucusana 海滩,将P. inca的分布范围向北延伸了约 1700 公里,从而成为该多叶物种的最北端记录。此外,还审查并列出了来自秘鲁的正式描述的 polyclads 物种。
