Abstract

Abstract The dajid parasite Holophryxus alaskensis Richardson, 1905a is reported from Pasiphaea pacifica Rathbun, 1902 collected at 1,200 m depth near Baja California, Mexico. This represents the southernmost record for this species at approximately twice the depth of prior records. A juvenile specimen of Holophryxus attached to Parapasiphae sulcatifrons Smith, 1884 collected at 1,625 m depth from the Bear Seamount (an underwater volcano in the western Atlantic Ocean) was found to be similar in morphology to juveniles of H. alaskensis. However, it is also not possible to determine whether it is conspecific with either of the known Atlantic species of Holophryxus (H. acanthephyrae Stephensen, 1912a and H. richardi Koehler, 1911). This is the first record of P. sulcatifrons as a host for any epicaridean. Finally, H. acanthephyrae is reported for the first time from off the Bahamas, where it was found on Acanthephyra pupurea A. Milne-Edwards, 1881 collected at 2,134 m depth. A discussion of the global distribution and taxonomic issues in the genus Holophryxus is provided.

标题1905年大西洋和太平洋Holophryxus Richardson种新记录(甲壳纲:等足目:大虾科)及其属分类问题的评述

摘要报道了在墨西哥下加利福尼亚州附近1200 m深度采集的太平洋帕西法亚(pasphaea pacifica Rathbun, 1902)大体型寄生虫Holophryxus alaskensis Richardson, 1905a。这代表了该物种最南端的记录，其深度大约是先前记录的两倍。在熊海山(西大西洋的一座水下火山)1625米深处采集到的附在Parapasiphae sulcatifrons Smith上的Holophryxus幼鱼标本，发现其形态与H. alaskensis幼鱼相似。然而，也不可能确定它是否与已知的大西洋Holophryxus物种中的任何一种(H. acanthephyrae Stephensen, 1912年和H. richardi Koehler, 1911年)同属。这是第一次记录的P. sulcatifrons作为宿主的任何epicaridean。最后，首次报道了在巴哈马群岛附近发现的棘足虫，它是在1881年在2134米深的海底收集的棘足虫。本文讨论了该属的全球分布和分类学问题。
