摘要 在东南太平洋秘鲁-智利海沟的深渊深处描述了 Hirondellea 的三个新种：Hirondellea sonne sp.。十一月，Hirondellea thurstoni sp。十一月和 Hirondellea wagneri sp。十一月区分这些物种的主要诊断特征是： 头外侧叶的形状；押语的形状；颌足动物 1 和 2 手掌的形状和方向； Epimeron 3 后腹角的形状；以及尾肢 2 外支上是否有切口。这使得该属中已知的物种数量达到 20 个。新物种得到了充分的描述和说明，并与 Hirondelleidae 中的所有其他物种进行了诊断。提供了世界物种的钥匙。 http://zoobank.org/urn:lsid:zoobank.org:pub:02BC79A0-FE30-4FE5-A8B8-2EC131C1342C
Abstract Three new species of Hirondellea are described from hadal depths of the Peru-Chile Trench in the southeast Pacific: Hirondellea sonne sp. nov., Hirondellea thurstoni sp. nov. and Hirondellea wagneri sp. nov. The main diagnostic characters distinguishing these species are: the shape of the lateral cephalic lobes; the shape of the epistome; the shape and orientation of the palm of gnathopods 1 and 2; the shape of the posteroventral corner of epimeron 3; and the presence or absence of an incision on the outer ramus of uropod 2. This brings the known number of species in the genus to 20. The new species are fully described and illustrated, and are diagnosed against all other species in the Hirondelleidae. A key to the world species is provided. http://zoobank.org/urn:lsid:zoobank.org:pub:02BC79A0-FE30-4FE5-A8B8-2EC131C1342C
