Four monogonont rotifers, Filinia hofmanni Koste, 1980, Lecane pusilla Harring, 1914, Mikrocodides chlaena (Gosse, 1886), and Proales fallaciosa Wulfert, 1937, were newly recorded in Korea. The genera Mikrocodides Bergendal, 1892 and Proales Gosse, 1886 were recorded for the first time in Korea. Mikrocodides chlaena and Proales fallaciosa were found from soil samples and are both soft-bodied species. Filinia hofmanni has previously been recorded mainly in Europe, and this is its first record in Asia. Lecane pusilla is the 24th lecanid rotifer recorded in Korea, and its morphological characteristics are consistent with previous research of L. pusilla. We have provided the morphological diagnoses of the four Korean specimens in this study, along with the partial sequences of mitochondrial cytochrome c oxidase subunit I(COI) gene of three species.

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.

In this study, we identified two marine synchaetid rotifers, Synchaeta grimpei Remane, 1929 and S. vorax Rousselet, 1902, in Korea, which are the first synchaetid rotifers collected from a marine environment in the country. Prior to this study, all six synchaetids recorded in Korea were collected from freshwater environments. The morphological characteristics of both species are consistent with those recorded in previous studies of each species. Synchaeta grimpei is distinguished from other synchaetid rotifers by its cone-shaped body, wide and flat apical field, indistinct auricles, and long foot with two separated small toes. The morphological characteristics of Korean S. vorax specimens were most similar to the original description of Rousselet (1902), with its slender and cylindrical trunk shape, strongly convex apical field, and short foot with two small, separated toes. The rami of the Korean S. vorax specimen contained one frontal hook and several distinct and large teeth. Here, we provide the morphological diagnoses of the two synchaetid rotifers and the sequences of the partial mitochondrial cytochrome c oxidase subunit I (COI) of the two species.

In this study, three lecanid rotifer species were newly recorded in Korea: Lecane inermis (Bryce, 1892), L. furcata (Murray, 1913), and L. nana (Murray, 1913). Most of the lecanid rotifers recorded in Korea have been collected from stagnant water, and Lecane furcata and L. nana were collected from a reservoir. In contrast, L. inermis was found in a soil sample. Lecane inermis is the first illoricated lecanid species reported in Korea. This species is distinguished from other illoricated species by its toes with relatively long claws. Lecane furcata is the most common lecanid rotifer in submerged vegetation. The morphological characteristics of its lorica are similar to many other lecanid rotifers, but it can be distinguished by its completely fused toes with a terminal fissure, an absence of antero-lateral spines, and the ratio of lorica/toe length. Lecane nana is most similar to L. tryphema Harring & Myers, 1926, but can be distinguished by the toe tips curved outwards. The three species in this study are considered to have a cosmopolitan distribution and have been recorded in many Asian countries. In this paper, we describe the morphological characteristics of the three lecanid species with trophi structures observed by scanning electron microscope.

Three newly recorded rotifers were collected through surveys of several islands in Korea: Lecane perplexa (Ahlstrom, 1938); Lindia torulosa Dujardin, 1841; and Monommata maculata Harring & Myers, 1930. These species represent 24th, second, and third records of each genus discovered in Korea, respectively. Lecane perplexa and Monommata maculata, were collected from reservoirs using plankton nets, whereas Lindia torulosa was collected from a soil sample. The morphological characteristics of the discovered species are as follows: Lecane perplexa is characterized by a straight or slightly concave anterior margin of the lorica, an incomplete transverse fold on the ventral lorica, and a single toe with pseudoclaws and accessory claws; Lindia torulosa has an illoricated and vermiform body, a head with rostrum, a pair of auricles, cardate type trophi, and distinctively shaped epipharynx components; and Monommata maculata is characterized by long toes, an inner margin of rami with 10-12 serrated teeth, 3-4 large teeth, and interlocking teeth. Here, the morphological characteristics of the three Korean monogonont rotifers, which include trophi photographs, are presented. In addition, partial sequences of the mitochondrial cytochrome c oxidase subunit I (COI) of each species are presented.
