| Abstract: |
| A brief morphometric study of the recent planktonic foraminifera in the eastern Indian Ocean was provided with the taxonomic key to species, synonyms, SEM microphotographs of shells and chamber arrays. By recent classification, currently 20 species representing 13 genera and 6 families (Canderinidae, Heterohelicoidae, Hedbergellidae, Higerigerinoidae, Globigerinoidae, and Globorotaloidae) identified from the planktonic material of the eastern Indian Ocean up to a depth of 200 m. Their distribution in water (0–200 m) also reports on the new range of expansion in the eastern Indian Ocean, with Dentigloborotalia anfracta, Hastigerina pelagica, Streptochilus globigerus, Globigerinella calida, Globigerinella adamsi, Orcadia reidelii, Tenuitella parkerae, Tenuitella compressa, reported for the first time in this study area. In general, only around 50 planktonic species are valid worldwide, more specifically the species, e.g., H. pelagica, G. calida, G. adamsi, S. globigerus, O. riedeli, T. parkerae, T. compressa, which occur in the eastern Indian Ocean to fill the the paucity of the recent regional taxonomic literature and the problematic identification from the eastern Indian Ocean. This work aims to bridge this gap and help scientists, managers, educators and students to identify plankton foraminifers by using species notes and images. |

| 本研究对东印度洋现生浮游有孔虫进行了形态统计，并提供了浮游有孔虫分类检索表、物种名以及浮游有孔虫的壳体和房室的SEM显微照片。在东印度洋0~200 m的浮游样品中共鉴定出20种浮游有孔虫，隶属于6科13属（Canderinae，Heterohelicoae，Hedbergellidae，Higerigerinoae，Globigerinoae，Globorotaloae）。其中在此研究海域中新发现的物种有Dentigloborotalia anfracta，Hastigerina pelagica，Streptochilus globigerus，Globigerinella calida，Globigerinella adamsi，Orcadia reidelii，Tenuitella parkerae，Tenuitella compressa）。目前，全球可鉴定出的浮游有孔虫大约有50种，其中本次研究中出现在东印度洋的H.pelagica、G.calida、G.adamsi、S.globigerus、O.riedeli、T.parkerae、T.compressa等物种填补了最近区域分类学文献的不足和东印度洋的鉴定问题。这将有利于科学家、管理人员、教育工作者和学生通过利用物种描述和图像识别东印度洋现生浮游有孔虫. |
