Abstract

Littoral rotifers were collected in three prefectural cities of the little studied Western Guangdong Province (Yangjiang, Maoming and Zhanjiang) in April 2017 and in July 2018. Fifty-six monogonont taxa, including two subspecies/variations, were found. Lecane zhanjiangensis sp. nov., a new brackish-water species from the littoral zone of Shimenhe River Estuary in Zhanjiang, is described. It is characterized by large semicircular projections antero-laterally on the dorsal plate, each equipped with three to five minute spines, and a pair of large acutely pointed projections antero-laterally on the ventral head aperture margin. In addition, three new rotifer records for China, viz. Brachionus cf. caudatus var. indica Novotná-Dvořáková, 1963, Ptygura libera Myers, 1934 and P. thalenoiensis Meksuwan, Pholpunthin Segers, 2011 are also presented.

摘要

2017年4月和2018年7月，在研究较少的粤西地区的三个地级市（阳江、茂名和湛江）采集了沿岸轮虫。共发现56个单巢纲分类单元，包括两个亚种/变种。描述了湛江同尾轮虫（Lecane zhanjiangensis sp. nov.），这是一种来自湛江石门河河口沿岸带的新咸水物种。其特征为背板前侧有大的半圆形突起，每个突起上有3至5根微小的刺，腹侧头部开口边缘前侧有一对大的尖锐突起。此外，还报道了在中国新记录的三种轮虫，即尾突臂尾轮虫疑似种（Brachionus cf. caudatus var. indica Novotná-Dvořáková, 1963）、自由褶缘轮虫（Ptygura libera Myers, 1934）和塔勒诺伊褶缘轮虫（P. thalenoiensis Meksuwan, Pholpunthin & Segers, 2011）。[物种动物学数据库注册：http://zoobank.org/urn:lsid:zoobank.org:act:E91C0C2A-8656-4999-B71C-00F39456F7A0]
