Systematic analysis shows that the Southern Hemisphere bivalve genus Retrotapes includes the Antarctic species R. antarcticus, R. newtoni, and R. robustus and recognizes for the first time the presence of Katelysia represented by K. florentinoi. Two new genera were erected in this study: Marciachlys new genus to include M. inflata new combination, and Adelfia new genus, which includes A. austrolissa new combination and A. omega new species from the Eocene of Antarctica, and the late Eocene Chilean A. arenosa new combination. Eurhomalea carlosi was synonymized with K. florentinoi; Cyclorismina marwicki with R. antarcticus; Gomphina iheringi was considered an indeterminate species; and Cockburnia lunulifera was excluded from the Tapetinae. These systematic assignments are supported by a phylogenetic analysis, which recognizes an Austral clade of Tapetinae, comprising all the genera mentioned above, along with Marcia, Paleomarcia, Atamarcia, and Protapes.UUID: http://zoobank.org/a8c91a9f-99ec-4235-8416-d398771a3eb2

来自 La Meseta 和 Submeseta 地层的始新世南极 Tapetinae Gray 的系统发育，1851 年（双壳类，Veneridae）

系统分析表明，南半球双壳类录像带包括南极物种R.南极洲,R.牛顿， 和R.健壮的并首次认识到存在凯莉西亚代表为ķ.佛罗伦萨. 在这项研究中建立了两个新属：马西亚赫利斯要包括的新属米.膨胀新组合，和阿德尔菲亚新属，其中包括一种.澳大利亚新组合和一种.欧米茄来自南极洲始新世和始新世晚期智利的新物种一种.阿雷诺萨新组合。荠菜是同义词ķ.佛罗伦萨;环线虫和R.南极洲；鹅掌楸被认为是不确定的物种；和刺槐被排除在 Tapetinae 之外。这些系统的分配得到了系统发育分析的支持，该分析识别了 Tapetinae 的南方进化枝，包括上述所有属，以及玛西娅,古马尔西亚,阿塔马西亚， 和Protapes.UUID：http://zoobank.org/a8c91a9f-99ec-4235-8416-d398771a3eb2
