摘要
目的：毛子叶属是毛子叶科中最大的一科植物，其分类地位尚不明确。本研究旨在通过描述一个新的毛子叶种C. jusstinemusei n. sp.（以前被鉴定为C. c.c.f yophryi），并澄清相关的同源种，特别是地中海和大西洋水域的sparids的分类地位，来解决这一歧义。方法根据在巴黎国立自然历史博物馆发现的地中海地区Pagellus acarne鳃标本，对其进行鉴定。通过形态学和解剖学特征，包括有无末端垂毛、环状器官、心房钩和睾丸的数量，将该物种与其同属物种区分开来。利用cox1序列进行分子分析也有助于物种鉴定。结果用几个关键的形态特征和分子序列对其进行了描述，并将其与其他毛子叶属植物区分开来。在大西洋水域发现的来自bogaraveo Pagellus chrysophryi的记录被重新划归为C. chrysophryi sensu Llewellyn（1941）。此外，发现P. bogaraveo的C. pagelli与C. chrysophryi sensu Llewellyn（1941）不同，证实了C. pagelli和C. chrysophryi作为独立种的有效性，并恢复了前者作为有效种的地位。此外，还对马里奥氏梭菌进行了鉴别诊断，根据其原始宿主Spicara maena恢复了马里奥氏梭菌。结论本研究明确了金翅草及其近缘种的分类地位，对金翅草进行了描述，恢复了金翅草和金翅草的有效种地位。这些发现有助于更准确地了解纤毛纲物种及其宿主特异性。
A Closer Look at the Choricotyle chrysophryi-like (Polyopisthocotyla: Diclidophoridae) Species Complex: Description of a New Choricotyle from the Gills of Pagellus acarne (Teleostei: Sparidae) and Revision of Choricotyle spp. from Sparids
Purpose
The genus Choricotyle, the largest in the diclidophoridean family, includes C. chrysophryi, whose taxonomic status remains ambiguous. This study aims to resolve this ambiguity by describing a new Choricotyle species, C. justinemusei n. sp. previously identified as C. cf. chrysophryi, and clarifying the taxonomic status of related congeneric species, particularly those reported from sparids in Mediterranean and Atlantic waters.
Methods
Choricotyle justinemusei n. sp. was described based on Mediterranean specimens from the gills of Pagellus acarne, found in the Muséum National d'Histoire Naturelle, Paris. The species was differentiated from its congeners through morphological and anatomical features, including the presence or absence of a terminal lappet, and of ring organ, number of atrial hooks and of testes. Molecular analysis using cox1 sequences was also conducted to aid in species identification.
Results
Choricotyle justinemusei n. sp. was described and distinguished from other Choricotyle species by several key morphological traits and molecular sequences. The record of C. chrysophryi from Pagellus bogaraveo in Atlantic waters was reassigned to C. chrysophryisensu Llewellyn (1941). Furthermore, C. pagelli from P. bogaraveo was found to be distinct from C. chrysophryi sensu Llewellyn (1941), confirming the validity of both C. pagelli and C. chrysophryi as separate species, and the former was reinstated as a valid species. A differential diagnosis was also provided for C. marionis, reinstating it based on its original type-host, Spicara maena.
Conclusion
This study clarifies the taxonomic status of C. chrysophryi and related species, describing C. justinemusei n. sp. and reinstating C. pagelli and C. marionis as valid species. These findings contribute to a more accurate understanding of Choricotyle species and their host specificity.
期刊介绍：
Acta Parasitologica is an international journal covering the latest advances in the subject.
Acta Parasitologica publishes original papers on all aspects of parasitology and host-parasite relationships, including the latest discoveries in biochemical and molecular biology of parasites, their physiology, morphology, taxonomy and ecology, as well as original research papers on immunology, pathology, and epidemiology of parasitic diseases in the context of medical, veterinary and biological sciences. The journal also publishes short research notes, invited review articles, book reviews.
The journal was founded in 1953 as "Acta Parasitologica Polonica" by the Polish Parasitological Society and since 1954 has been published by W. Stefanski Institute of Parasitology of the Polish Academy of Sciences in Warsaw. Since 1992 in has appeared as Acta Parasitologica in four issues per year.
