The rare freshwater copepod Eucyclops (Speratocyclops) productus Kiefer, 1939 from Lake Mandongco, Tibet Autonomous Region, China, is redescribed. This species was originally found and described from a pond south of Chushul village, and many of the details did not meet modern standards for describing the species. In this paper, the morphological characteristics of this species are described in detail and compared with other members of the subgenus Speratocyclops species recorded in China. The key features of the species are: 1) long caudal rami, 2) the coxal seta of the fourth pair of legs armed with long hairs in the proximal part and short denticles in the distal part, 3) the inner spine of the fifth pair of legs long and strong. An identification key to 22 species of Eucyclops known from China and adjacent areas is also provided.
中国西藏自治区芒多错湖的罕见淡水桡足类 Eucyclops (Speratocyclops) productus Kiefer, 1939 被重新描述。该物种最初是在楚舒尔村南部的一个池塘中发现并描述的，其许多细节不符合现代物种描述的标准。本文详细描述了该物种的形态特征，并与在中国记录的 Speratocyclops 亚属的其他物种进行了比较。该物种的主要特征为：1）尾叉长；2）第四对附肢的基节具长而密的毛和短的小齿；3）第五对附肢的内刺长而强壮。还提供了一份来自中国及周边地区的 22 种已知 Eucyclops 的鉴别特征。
