Abstract

Currently comprising 12 species infecting the gastrointestinal tracts of diurnal raptors (Falconiformes, Accipitriformes), species of Cladotaenia are diagnosed by their branching uterus, testes in two fields reaching the same level anteriorly, and small rostellum armed with taenioid hooks arranged in two rows. In this study we describe a new species of Cladotaenia recovered from a number of Australasian harriers Circus approximans, from the southern half of South Island, New Zealand. The new species is distinguished from other species by its single circle of hooks. It is closest, morphologically, to C. circi, but differs in the shape of the terminal proglottids and the number of uterine branches. Sequences of 28S and cox1 gene are presented. Genetically, Cladotaenia anomala n. sp. is closest to Cladotaenia globifera but differs morphologically in the size of the suckers, testes and eggs. This description constitutes the first record of a Cladotaenia species in New Zealand. We discuss some potential routes this parasite may have taken to arrive in New Zealand.

新西兰澳鹞（Circus approximans Peale）新寄生虫Cladotaenia anomala n. sp.（Paruterinidae）的描述和分子数据。

目前，感染昼行性猛禽（隼形目、啄木鸟形目）胃肠道的 Cladotaenia 有 12 个种，它们的特征是子宫有分枝，睾丸分两块，前部达到同一水平，小喙上有两排排列的栉状钩。在这项研究中，我们描述了从新西兰南岛南半部的一些澳大利亚鹞Circus approximans身上发现的Cladotaenia新种。这个新物种与其他物种的区别在于它只有一圈钩。从形态上看，它与 C. circi 最为接近，但在末端前叶的形状和子宫分支的数量上有所不同。本文介绍了 28S 和 cox1 基因的序列。在基因上，Cladotaenia anomala n. sp.最接近于Cladotaenia globifera，但在吸盘、睾丸和卵的大小上存在形态差异。这一描述首次记录了新西兰的一种Cladotaenia物种。我们讨论了这种寄生虫到达新西兰的一些可能途径。

期刊介绍： Systematic Parasitology publishes papers on the systematics, taxonomy and nomenclature of the following groups: Nematoda (including plant-parasitic), Monogenea, Digenea, Cestoda, Acanthocephala, Aspidogastrea, Cestodaria, Arthropoda (parasitic copepods, hymenopterans, mites, ticks, etc.), Protozoa (parasitic groups), and parasitic genera in other groups, such as Mollusca, Turbelleria, etc. Systematic Parasitology publishes fully illustrated research papers, brief communications, and fully illustrated major revisions. In order to maintain high standards, all contributors describing new taxa are asked to state clearly where the holotype is deposited and to make paratypes available for examination by the referees. It is recognized that, in some cases, this may cause problems for the authors, but it is hoped that by adhering to this rule authors may be protected against rapid synonymy of their taxa, and the types will be preserved for posterity.
