Abstract

A detailed redescription of two endemic, cave-dwelling niphargid species of the Hungarian Mecsek Mts., Niphargusmolnari Méhely, 1927 and Niphargusgebhardti Schellenberg, 1934 is given based on newly collected material. Morphology was studied under light microscopy and with scanning electon microscopy. Morphological descriptions are complemented with mitochondrial cytochrome c oxidase subunit I (COI) sequences as barcodes for both species and with notes on their ecology. Using three independent molecular markers we showed that Niphargusgebhardti belongs to the clade distributed between Central and Eastern Europe, whereas phylogenetic relationship of Niphargusmolnari to the rest of Niphargus species is not clear. The two species from the Mecsek Mts. are phylogenetically not closely related. Both species need to be treated as vulnerable according to IUCN Red List of Threatened Species.

摘要

基于新采集的材料，对匈牙利迈切克山脉特有的两种穴居仙女虾物种——1927年的莫氏仙女虾（Niphargus molnari Méhely）和1934年的格氏仙女虾（Niphargus gebhardti Schellenberg）进行了详细的重新描述。在光学显微镜和扫描电子显微镜下研究了其形态。形态学描述辅以两种物种的线粒体细胞色素c氧化酶亚基I（COI）序列作为条形码，并对它们的生态学进行了注释。使用三个独立的分子标记，我们表明格氏仙女虾属于分布在中欧和东欧之间的进化枝，而莫氏仙女虾与其他仙女虾物种的系统发育关系尚不清楚。来自迈切克山脉的这两个物种在系统发育上关系并不密切。根据国际自然保护联盟濒危物种红色名录，这两个物种都需要被视为易危物种。
