本文记载了福建省的淡水轮虫151种,其中新种1个,国內新记录2个。文章还对福建淡水轮虫的种类分布作了概述。

The present paper records one hundred and fifty-one species of Fujian fresh- water rotifers, which belong to two orders, thirteen families and fifty-one genera. Among them, Notholca fujianensis sp. nov. is considered to be new to science, while Lepadella rhomibodis and Testudinalla tridentata are recorded for the first time from China. The charicteristic features of the new taxa are epitomized asfollow:Notholca fujianensis sp nov.Type (FUN-001) Ping-tan Island, March 16, 1989.The lorica is transparent. Viewing both from dorsal and ventral sides, it is long tube-shaped. The dorsal plate turns inward toward the ventral. There are three pairs of spines at the anterior end of the dorsal plate, the longest pair are at the antero-lateral edge which locates entirely in the ventral due to the curving of the dorsal plate. The postlorica is with a postero-shaft. There is a deep middle concavity in the anterior ventral plate. There are 22 longitudinal striations on the dorsal plate but 14 while on the ventral late.total length: 178.7μmthe greatest width: 46.7μmpostero-shaft length: 20.6μmantero-lateral spine length: 20.1μm The sample was collected from San-shi liu jiao lake of Ping-tan Island, Fujian province on Marth 16, 1989.Remarks: This species resembles N. tibetenensis Gong 1983, with the following morphological differences:(1) The new species has a postero-shaft;(2) Its lateral spines is the longest ones;(3) The lorica of new species looks like cylindric in form, but it is ovaliform actually. The laterals margin of Iorica extends ventrally and wraps ventral plate at widest place, leaving only a crack on the center of ventral side.Type specimens is deposited in the department of biology, Fujian Normal University.
