摘要
Ergasilus lizae Krøyer, 1863 是一种寄生桡足类，已知会感染世界各地的鲻鱼（鲻科）。它最初是在北美洲东海岸被报道的，但原始描述不够详细，因此很难根据这些信息进行鉴定。在本研究中，我们重新描述了在墨西哥西北部两个沿海泻湖（温暖/多雨和寒冷/干燥）中捕获的 Mugil curema Valenciennes 和 M. cephalus Linnaeus 身上发现的 E. lizae。这种寄生虫在温暖季节的流行率高于寒冷季节。为了便于进行物种鉴定，我们生成了伊蚊条形码基因（COI mtDNA）的新序列，并与生命条形码数据库（BOLD）中未发表的伊蚊序列进行了比较。我们的结果表明，BOLD 的序列可能属于一个被误认为是 E. lizae 的物种。
Morphology, DNA barcoding and seasonal occurrence of Ergasilus lizae Krøyer, 1863 (Copepoda: Ergasilidae) parasitizing mullets from northwestern Mexico.
Ergasilus lizae Krøyer, 1863 is a parasitic copepod known to infect mullets (Mugilidae) in different parts of the world. It was originally reported from the east coast of North America, but the original description lacks enough detail, making identification with this information difficult. In this study, we provide a redescription of E. lizae found on Mugil curema Valenciennes and M. cephalus Linnaeus, caught in two coastal lagoons of northwestern Mexico during two climatic seasons: warm/rainy and cold/dry. The prevalence of this parasite was higher in the warm season than in the cold season. To facilitate the species identification, new sequences of the barcoding gene (COI mtDNA) of E. lizae were generated and compared against unpublished sequences of E. lizae available in the Barcode of Life Database (BOLD). Our results suggest that the sequences of BOLD possibly belong to a species misidentified as E. lizae.
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.
