摘要

摘要Pisione Grube,1857年被认为是稀有动物,但近几十年来其数量有所增加。新物种已被描述,主要来自印度-太平洋地区。在本研究中,我们描述了来自印度东南海岸泰米尔纳德邦的Pisione balasubramaniani sp.nov。新物种在交配器官的形状上类似于“远程复合体”中的其他物种,第一节上有细长的腹侧卷须,第二节上有短的背侧卷须。它可以通过从最前面到最后一个毛虎具有突出的脊索、毛虎15-17上的三对交配器官以及交配器官的形态变化来与该组成员区分开来。我们还根据关键的形态学特征,提供了所有已知Pisione物种之间的最新比较。我们还对印度和附近地区的该属物种进行了讨论。

A new species of Pisione (Annelida, Sigalionidae) from Palk Bay, India
Abstract Pisione Grube, 1857 was considered rare animals, but its numbers have increased in recent decades. New species have been described, mainly from the Indo-Pacific region. In this study, we described Pisione balasubramaniani sp. nov., from Tamil Nadu, southeastern coast of India. The new species resembles other species in the ‘remota complex’ in the shape of the copulatory organs, elongated ventral cirri on the first segment and a short dorsal cirrus on the second segment. It can be distinguished from members of this group by having protruding notoacicula from the anteriormost to the very last chaetigers, three pairs of copulatory organs on chaetigers 15–17 and variances in the morphology of the copulatory organ. We also provide an updated comparison between all known species of Pisione based on key morphological characters. We also present a discussion of species of this genus in India and nearby regions.
