Abstract
The present study describes five newly recorded modern benthic foraminiferal species from the subtidal zone near Jeju Island and East China Sea (Korea). The newly recorded species (Karrerulina conversa, Rotaliammina trumbulli, Vertebralina striata, Pegidia dubia and Amphistegina radiata) belong to five families (Prolixoplectidae, Trochamminidae, Fischerinidae, Pegidiidae and Amphisteginidae), three orders (Lituolida, Miliolida and Rotaliida) and two classes (Globothalamea and Tubothalamea). All these five genera (Karrerulina, Rotaliammina, Vertebralina, Pegidia and Amphistegina) were also reported for the first time from Korean waters. Most of the examined specimens were highly consistent morphologically with previous records from southern China and Japan. Additionally, Amphistegina is one of the symbiont-bearing larger benthic foraminifera, known to be mainly distributed in tropical to warm subtropical waters. This study contributes to the expansion of data on the recent foraminiferal species diversity in Korean waters.
Highlights
The purpose of this study is to describe an additional five newly recorded recent benthic foraminiferal species from around Jeju Island and East China Sea (Korea)
Five newly recorded recent benthic foraminiferal species belonging to five genera (Amphistegina, Karrerulina, Pegidia, Rotaliammina, Vertebralina), five families (Amphisteginidae, Fischerinidae, Pegidiidae, Prolixoplectidae, Trochamminidae), and three orders (Lituolida, Miliolida and Rotaliida) were discovered in the waters around Jeju Island, and East China
All five genera are recorded for the first time in Korea, and in particular, Amphistegina is a symbiont-bearing tropical to subtropical larger benthic foraminifera
Summary
This study contributes to the expansion of data on the recent foraminiferal species diversity in Korean waters. After the year 2010, taxonomic and diversity studies on benthic foraminifera have been conducted for 10 years in areas not previously investigated before, such as East Sea (Japan Sea) and East China Sea in the southern Jeju Island, and in line with it, several newly recorded species (218 species) or new species (1 species) have been reported [6,7,8,9,10]. The purpose of this study is to describe an additional five newly recorded recent benthic foraminiferal species from around Jeju Island and East China Sea (Korea)
