Abstract

A halacarid mite, Bradyagaue drygalskii (Lohmann, 1907), in the family Halacaridae, was discovered from the brown alga Desmarestia chordalis Hooker and Harvey, 1845, at a depth of 12 m in Lützow-Holm Bay on the East Antarctic coast during the 35th Japanese Antarctic Research Expedition in 1994. This is the first record of B. drygalskii from the region of Queen Maud Land to Enderby Land in East Antarctica. This finding supports the contention that B. drygalskii will be distributed widely in Antarctica. The results of morphological comparison and distributional records for Bradyagaue species described so far suggested that B. aspidionis Newell, 1984, and B. drygalskii are likely to be conspecific. However, further detailed comparisons are necessary to clarify the taxonomic relationship between these two species based on a greater number of individuals.

东南极洲l zow- holm湾halacaria螨Bradyagaue drygalskii （halacaro总科，螨目）的首次记录

1994年第35次日本南极科考考察队在南极东海岸l佐霍尔姆湾12米深处从褐藻Desmarestia chordalis中发现了一种Halacaridae螨，Bradyagaue drygalskii (Lohmann, 1907)，属于Halacaridae科。这是东南极洲莫德女王地至恩德比地地区首次记录到drygalskii。这一发现支持了B. drygalskii将在南极洲广泛分布的论点。经形态学比较和分布记录的结果表明，B. aspidionis Newell， 1984和B. drygalskii可能是同种的。然而，为了在更多的个体数量的基础上阐明这两个物种之间的分类关系，还需要进一步的详细比较。

期刊介绍： Polar Science is an international, peer-reviewed quarterly journal. It is dedicated to publishing original research articles for sciences relating to the polar regions of the Earth and other planets. Polar Science aims to cover 15 disciplines which are listed below; they cover most aspects of physical sciences, geosciences and life sciences, together with engineering and social sciences. Articles should attract the interest of broad polar science communities, and not be limited to the interests of those who work under specific research subjects. Polar Science also has an Open Archive whereby published articles are made freely available from ScienceDirect after an embargo period of 24 months from the date of publication. - Space and upper atmosphere physics - Atmospheric science/climatology - Glaciology - Oceanography/sea ice studies - Geology/petrology - Solid earth geophysics/seismology - Marine Earth science - Geomorphology/Cenozoic-Quaternary geology - Meteoritics - Terrestrial biology - Marine biology - Animal ecology - Environment - Polar Engineering - Humanities and social sciences.
