Abstract

The description of a new species of an erymid lobster, Stenodactylina beardi, from the Upper Cretaceous Haslam Formation of the Nanaimo Group on Vancouver Island, British Columbia, Canada, brings to fifteen the number of Erymidae in North America. The species are arrayed within five genera based upon configuration of carapace groove morphology, resulting in two new combinations, Stenodactylina bordenensis (Copeland, 1960) and S. foersteri (Feldmann, 1979). The new species exhibits for the first time a male pleopod and accessory structures within Erymoidea. We also provide a list of the North American species of Erymoidea.

来自加拿大不列颠哥伦比亚省上白垩统的一种新的类红龙虾（十足目：Glypheidea：毛ry科），以及北美的毛ry的摘要

摘要

来自加拿大不列颠哥伦比亚省温哥华岛的纳奈莫集团上白垩纪哈斯拉姆组的一种新的红斑龙虾，Stenodactylina beardi的描述，使北美的黑斑龙数量增加到十五。根据甲壳沟的形态，将其排列在五个属中，从而产生了两个新的组合，即Stenodactylina bordenensis（Copeland，1960）和S. foersteri（Feldmann，1979）。新物种首次在雄性目ide虫内显示出雄性腹足和附属结构。我们还提供了北美Erymoidea物种的列表。
