上皇さま、ハゼの新種２種発見　命名も、退位後初の論文―宮内庁

　宮内庁は２４日、上皇さまがハゼの新種を２種発見されたと発表した。英語の論文は５月に日本魚類学会の英文誌オンライン版に掲載された。上皇さまのハゼに関する論文は３４本目で、退位後は初めて。新種発見の発表は１８年ぶりで、計１０種となった。
　同庁によると、新種として発表したのは、沖縄県・座間味島や西表島などで２００１～０８年に皇居・生物学研究所の職員が採集したオキナワハゼ属の２種。頭部にある感覚器などの形態的な違いを分析した結果、新種と判明し、上皇さまが「アワユキフタスジハゼ」と「セボシフタスジハゼ」と命名した。（2021/06/24-17:22）

Japanese Emperor Emeritus Akihito has found two new goby fish species, the Imperial Household Agency said Thursday.
   The paper on the discovery was published online in May in the English version of the journal by the Ichthyological Society of Japan. It is the 34th paper related to goby fish by the Emperor Emeritus and the first since he abdicated in 2019.
   The latest discovery is the first of its kind by him in 18 years, bringing the total number of new goby fish species he has found to 10.
   According to the agency, the two new species were collected in the islands of Zamami and Iriomote in the southernmost Japan prefecture of Okinawa between 2001 and 2008 by staff at the biological research institute of the Imperial Palace in Tokyo.
   They turned out to be new species after Emperor Emeritus Akihito analyzed sensory organs on the heads of the fish and other features.
