A new species of Hemicorallium Gray, 1867 (Coralliidae), Hemicorallium meraboshi sp. nov., is described here. The specimen was found at a depth of 1744–1755 m, approximately 340 km east of the Honshu (mainland Japan) coast. The colony was identified by visual and microscopic observation of standard morphological characteristics (colony size, diameters of colony base and branches, diameter and height of autozooid mound, thickness of coenenchyme, sclerite sizes, etc.) along with support from molecular evidence. The unique features of this specimen are the large (more than 2 mm in diameter) autozooid mounds and the sizable sclerites in the coenenchyme (over 0.1 mm long) that are 8-radiates and multi-radiates predominantly. This new species is the northernmost record of Pacific precious corals.

Two large specimens [310–476 mm standard length (SL)] of the genus Hoplostethus Cuvier in Cuvier and Valenciennes, 1829, collected from Iwate and Okinawa prefectures, Japan, were recently discovered and identified as Hoplostethus grandperrini Roberts and Gomon, 2012 on the basis of the following characteristics: large body size, exceeding 300 mm SL; abdominal scutes strong; pectoral fins light red; caudal-fin tip without black pigmentation; upper margin of eye almost horizontally level with lateral-line origin; predorsal scales not enlarged; fin spines moderately thickened; pectoral-fin tip not reaching anal-fin origin; anterior part of oral cavity, including underside of tongue, without black pigmentation; 15–17 pectoral-fin rays; 21 predorsal scales; and 13 or 14 abdominal scutes. Furthermore, a molecular phylogenetic analysis of a partial sequence of the mtDNA COI gene from one of the specimens placed it in the same clade as H. grandperrini previously recorded from Taiwan, with an uncorrected p-distance between both specimens of 0.19%. Hoplostethus grandperrini was originally described on the basis of two specimens collected off New Caledonia, with only one additional specimen having been reported (from southern Taiwan). The Japanese specimens are the first records of the species from Japan, the fourth and fifth specimens known, and the Iwate Prefecture specimen the northernmost record of the species.
1829年在日本岩手县和冲绳县发现的居维叶和瓦朗谢纳的两个大标本[310-476 mm标准长],最近被发现并鉴定为Hoplostethus grandperrini Roberts和Gomon,基于以下特征:体型大,超过300 mm SL;腹部护甲结实;胸鳍淡红色;尾鳍尖端没有黑色色素沉着;眼的上边缘几乎水平水平与侧线原点;不增大的前背鳞;鳍刺中等加厚;胸鳍尖端不达到肛门鳍的起源;口腔前部,包括舌下,无黑色色素沉着;15-17条胸鳍鳍;21前背鳞;还有13或14个腹肌。此外,对其中一个标本的mtDNA COI基因部分序列的分子系统发育分析表明,它与先前在台湾记录的H. grandperrini属于同一进化支,两个标本之间未经校正的p距离为0.19%。大佩里尼翼龙最初是根据在新喀里多尼亚采集的两个标本被描述的,只有一个额外的标本被报告(来自台湾南部)。日本的标本是该物种在日本的第一个记录,是已知的第四个和第五个标本,岩手县的标本是该物种最北的记录。

In Japan, the native population of the Oriental White Stork Ciconia boyciana Swinhoe, 1873 had been extinct in 1986, when the last captured stork died in a breeding facility. Later on, some wild or bred storks from Russia and mainland China (clear origin unknown) were transported to Japan, and their descendants were repeatedly released into natural fields to establish wild populations in this country. In this study, the feather mite Pelargolichus orientalis Waki, Mironov, and Shimano, 2023 has been collected from a taxidermy specimen of the Oriental White Stork belonging to a Japanese native population and preserved in the Himeji City Science Museum, Japan. Pelargolichus orientalis is the only feather mite species detected and described from the introduced storks bred in a Japanese zoo in our previous study. The present study shows that P. orientalis did occur in the Japanese native host population.
在日本,1873年出生的东方白鹳(Ciconia boyciana Swinhoe)在1986年灭绝,当时最后一只被捕获的白鹳在一个繁殖设施中死亡。后来,一些来自俄罗斯和中国大陆的野生或繁殖的鹳(来源不明)被运往日本,它们的后代被反复释放到自然领域,在日本建立了野生种群。本研究中,羽螨Pelargolichus orientalis Waki, Mironov, and Shimano, 2023从属于日本本土种群的东方白鹳标本中采集,保存在日本姬路市科学博物馆。东方卷毛螨是本研究中唯一在日本动物园引种鹳中发现并描述的羽螨种。本研究表明,东洋蓟确实存在于日本本土寄主种群中。
