Abstract

Two new species of the caridean shrimp genus Hippolyte Leach, 1814 [in Leach, 1813-14] are described from the Tropical Central and East Atlantic. Hippolyte cedrici sp. nov., from Príncipe and São Tomé, can be distinguished from both the related H. holthuisi Zariquey Álvarez, 1953 and H. varians Leach, 1814 on the basis of rostral dentition, as well as meristics of the ambulatory pereiopods. Hippolyte karenae sp. nov., from St. Helena, is morphologically similar to H. coerulescens (Fabricius, 1775) and H. obliquimanus Dana, 1852, by having a well-developed tooth on the outer angle of the first peduncular article of the antennula. It differs from these species, amongst other characters, primarily in the armature of the ambulatory dactyli. Specimens were collected from hydrozoan, antipatharian and alcyonarian cnidarians.

摘要

本文描述了1814年（见于利奇1813 - 1814年的著作）的铠甲虾属（Hippolyte Leach）的两个新物种，它们发现于热带中东大西洋海域。来自普林西比岛和圣多美岛的希波吕忒·塞德里希新种（Hippolyte cedrici sp. nov.），可以根据其吻齿以及步足的可数特征，与相关物种1953年的霍尔修斯铠甲虾（H. holthuisi Zariquey Álvarez）和1814年的变异铠甲虾（H. varians Leach）区分开来。来自圣赫勒拿岛的希波吕忒·卡雷纳新种（Hippolyte karenae sp. nov.），在形态上与1775年的青灰铠甲虾（H. coerulescens (Fabricius)）和1852年的斜手铠甲虾（H. obliquimanus Dana）相似，其触角第一节的外角上有一颗发育良好的齿。它与这些物种的不同之处，主要在于步足指节的武装等特征。标本采集自水螅虫纲、黑珊瑚纲和海鸡冠目珊瑚虫纲的动物。
