In the benthic samples collected during the deep-sea expeditions ANDEEP from the Weddell Sea and DIVA from the Argentine Basin the isopod family Munnopsidae was the most specious and numerous. Among the collected munnopsids three new species of Tytthocope Wilson & Hessler, 1981 have been discovered. Tytthocope is one of six genera of the subfamily Eurycopinae. It differs from other genera of the Eurycopinae by having a strongly reduced pereonite 7 and inflated pleotelson. Until now the genus consisted of five described species: four of them are known from the northern Atlantic and only one species, T. sulcifrons (Barnard, 1920) was described from the southern Atlantic off the South Africa coast. The five known species of Tytthocope have been recorded from depths less than 1461 m. Descriptions of three new species of Tytthocope collected in the South Atlantic and Southern Ocean at depths between 1530-4608 m, T. divae sp. nov., T. fahrbachi sp. nov. and T. longitelson sp. nov. are presented in the paper. T. sulcifrons is redescribed herein based on the type material.
在从威德尔海进行的深海探险ANDEEP以及从阿根廷盆地进行的DIVA探险期间采集的底栖生物样本中，等足目动物蒙诺普斯科是种类最多且数量最多的。在所采集的蒙诺普斯科动物中，发现了三种1981年由威尔逊和赫斯勒命名的新泰氏等足虫物种。泰氏等足虫是宽尾亚科六个属之一。它与宽尾亚科的其他属不同，其第7胸节强烈退化，尾节膨胀。到目前为止，该属包括五个已描述的物种：其中四个来自北大西洋，只有一个物种，即南非海岸外南大西洋的沟额泰氏等足虫（巴纳德，1920年）。泰氏等足虫的五个已知物种记录于深度小于1461米处。本文介绍了在南大西洋和南大洋1530 - 4608米深度采集的三种新泰氏等足虫物种，即迪瓦泰氏等足虫新种、法尔巴赫泰氏等足虫新种和长尾节泰氏等足虫新种的描述。本文根据模式标本对沟额泰氏等足虫进行了重新描述。
