Some rotifers from Republic of Korea

A new species of the genus Cephalodella (Rotifera, Monogononta) from Korea, with reports of four additional cephalodellid species

“… Cephalodella tinca is probably a cosmopolitan species and has been recorded in the Australian, Neotropical, Oriental, and Palearctic regions ( Segers 2007 ). The remaining two species, C. auriculata and C. catellina were recorded in Korea by Turner (1986) as a species list without description. Therefore, we described the Korean specimens of the two species and provided photographs of the trophi observed using SEM .…”

“…Two species, Cephalodella gracilis (Ehrenberg, 1830) and C. tinca Wulfert, 1937 were newly recorded in Korea and two others, C. auriculata and C. catellina, have previously been recorded in Korea. However, since the first reported paper on rotifers in Korea (Turner, 1986) did not include descriptions for these two species, we have described the two Korean specimens in this study. Here, we provide the morphological characteristics of the five species along with the photographs of trophi observed with scanning electron microscope (SEM).…”

“…In Korea, a total of seven cephalodellid species have been recorded: Cephalodella auriculata (Müller, 1773), C. catellina (Müller, 1786), C. forficula (Ehrenberg, 1838), C. gibba (Ehrenberg, 1830), C. hoodii (Gosse, 1886), C. innesi Myers, 1924, and C. ventripes (Dixon-Nuttall, 1901) ( Yamamoto 1953 ; Turner 1986 ; Song and Jin 2000 ; Song 2014 ; Song 2018 ; National Institute of Biological Resources 2022 ). Including the genus Cephalodella , studies on the species diversity of the family Notommatidae Hudson & Gosse, 1886 in Korea are insufficient.…”

Redescription of Lindia gravitata with comments on L. tecusa (Rotifera: Monogononta: Lindiidae)

“…As for L. gravitata, L. tecusa was reported from Scandinavian coastal waters, and the Baltic and North Sea as well, and moreover from the Black Sea, and the Atlantic coasts of Brittany, France, and Cape Breton Island, Nova Scotia, Canada (De Ridder & Segers, 1997). The report of L. tecusa from garden ponds in Tokyo, Japan, by Sudzuki (1975) is a misidenti¢cation, judging from the accompanying microphotograph, and the record from plankton of an eutrophic freshwater pond in Korea (Turner, 1986) is unveri¢able.…”
