New Record of Kellicottia bostoniensis and Redescription of Two Freshwater Rotifers from Korea (Rotifera: Monogononta)

초록

In this study, we identified three monogonont rotifers from South Korea: Kellicottia bostoniensis (Rousselet, 1908), Trichocerca tenuior (Gosse, 1886), and Lepadella triptera (Ehrenberg, 1830). The distribution records of K. bostoniensis were mainly located in the Nearctic, Neotropic and Western Palearctic regions. After Japan, this is the second record of it in Asia. Trichocerca tenuior and Lepadella triptera have already been recorded in Korea, but the data of two species were insufficient in previous study. Here, we describe the morphological characteristics of the three species and the trophi structures of K. bostoniensis and T. tenuior. This study is the first to characterize the trophi structure of K. bostoniensis, observed using a scanning electron microscope. In addition, we have determined the partial cytochrome c oxidase subunit 1 (COI) and 18S rRNA gene sequences of T. tenuior and L. triptera for their DNA barcodes.
