Hexanchus nakamurai is a deep‐water species, with very little scientific information. This study confirms the distribution of the species in the most eastern region of the Mediterranean Sea, Levantine Sea, in addition to providing some biological information from four pregnant individuals, which is being reported for the first time in the Mediterranean Sea. A total of four individuals were bycaught, in two sets on opposite coasts, three on the 13th of May 2020 from the western coast, and an individual on the 14th June 2020 from east coast of the island of Cyprus. The four specimens, all pregnant females, measured between 107 and 116 cm in total length and between 4,330 and 4,960 g in weight. All specimens were in early pregnancy according to the level of embryo development, which confirms that the size at maturity is smaller than previously reported. In the stomachs, remains of the hake Merluccius merluccius, the cephalopod Loligo vulgaris and two unidentified species of Hirudinea (Annelida) were found. This study provides important new information on the Mediterranean distribution of a globally rare and data deficient species, including an expansion of its known range, dietary preferences and insights of its reproduction biology; the first pregnant females reported in the Mediterranean Sea.

镇上的一个新物种：黎凡特海的1962年的Hexanchus nakamurai Teng的新纪录

六角形中村是一种深水物种，科学信息很少。这项研究证实了该物种在地中海最东部地区黎凡特海的分布，此外还提供了来自四个怀孕个体的一些生物学信息，这是地中海地区的首次报道。共有4个人被捕，在对面的海岸有两组，分别在2020年5月13日从西海岸被捕和3个人，在2020年6月14日从塞浦路斯岛东海岸被捕。四个标本均为孕妇，总长在107至116厘米之间，体重在4,330至4,960克之间。根据胚胎发育水平，所有标本都处于怀孕早期，这证实了成熟时的大小比以前报道的要小。在肚子里发现了水l（Meluuccius meluccius），头足类（Loligo vulgaris）和两个未鉴定的Hirudinea（Annelida）物种。这项研究提供了有关全球稀有和数据不足物种地中海分布的重要新信息，包括其已知范围的扩大，饮食偏好以及其繁殖生物学的见解；第一批孕妇在地中海报道。
