ABSTRACT

We describe a new pycnogonid species, Pantopipetta lenis sp. nov., collected from 141–152 m depth in southern Japan, North Pacific Ocean. Pantopipetta lenis closely resembles Pantopipetta auxiliata and Pantopipetta oculata in having auxiliary claws on the legs, but differs from them in lacking dorsodistal tubercles on the lateral processes, having the first short distal article of palp shorter than combined length of the other three short distal articles, having one slight dorsal tubercle on the coxa 1 of legs, having a short dorsal tubercle on the coxa 3 of legs, and lacking a long dorsodistal tubercle on the femur of legs. The palp base (the short article-like structure proximal to the longest palp article) in P. lenis is articulated with the cephalon, i.e. it is actually an article. Although the palp base has been regarded as a lateral process of the cephalon, it is the first article of the palp in P. lenis.

摘要

我们描述了一个新的食肉动物物种，Pentopipetta lenis sp。nov。，收集自日本南部北太平洋的141-152 m深度。Pantopipetta lenis与Pantopipetta auxiliata和Pantopipetta oculata极为相似，在腿上有辅助爪，但与它们的不同之处在于，在侧突上没有背脊结节，第一个短的远侧article毛比其他三个短的远侧articles齿的总长度短，在小腿的尾骨1上有一个轻微的背小结节，小腿的尾骨3上有一个短的背小结节，在小腿的股骨上没有一个长的后背结节。触须碱（短条状结构接近所述最长触须文章）在P. lenis与头颅相连，即实际上是一篇文章。尽管the骨基部被认为是头突的横向过程，但它是P. lenis中pa骨的第一篇文章。
