Information about the parasite fauna of spectacled porpoises and cetaceans from New Zealand waters in general is scarce. This study takes advantage of material archived in collections of the Otago Museum in Dunedin and Massey University in Auckland, sampled from cetacean species found stranded along the New Zealand coastline between 2007 and 2014. Parasites from seven species of cetaceans (spectacled porpoise, Phocoena dioptrica (n = 2 individuals examined); pygmy sperm whale (n = 1); long-finned pilot whale, Globicephala melas (n = 1); Risso's dolphin, Grampus griseus (n = 1); short-beaked common dolphin, Delphinus delphis (n = 7); striped dolphin, Stenella coeruleoalba (n = 3) and dusky dolphin, Lagenorhynchus obscurus (n = 2)) from the respiratory and gastro-intestinal tract, cranial sinus, liver, urogenital and mammary tract, fascia and blubber were investigated. Ten parasite species were identified, belonging to the Nematoda (Stenurus minor, Stenurus globicephalae, Halocercus sp. (Pseudaliidae), Anisakis sp. (Anisakidae), Crassicauda sp. (Crassicaudidae)), Cestoda (Phyllobothrium delphini and Monorygma grimaldii (Phyllobothriidae)), Trematoda (Brachicladium palliata and Brachicladium delphini (Brachicladiidae)) and Crustacea (Scutocyamus antipodensis (Cyamidae)). Some of the parasite species encountered comprises new records for their host. Although the material was not sampled within a systematic parasitological survey, the findings contain valuable new information about the parasite fauna of rare, vagile and vulnerable marine wildlife from a remote oceanic environment.
总体而言，关于新西兰海域眼镜斑纹海豚及其他鲸类动物的寄生虫群落信息非常稀少。本研究利用了存于但尼丁奥塔哥博物馆和奥克兰梅西大学馆藏的材料，这些材料取自2007年至2014年间在新西兰海岸搁浅的鲸类物种。对来自7种鲸类动物（眼镜斑纹海豚，暗黑斑纹海豚（共检查2头个体）；侏儒抹香鲸（1头）；长鳍领航鲸，巨头鲸（1头）；里氏海豚，灰海豚（1头）；短吻普通海豚，真海豚（7头）；条纹海豚，蓝白海豚（3头）和暗色斑纹海豚，暗淡斑纹海豚（2头））的呼吸道、胃肠道、颅窦、肝脏、泌尿生殖系统和乳腺、筋膜及鲸脂中的寄生虫进行了调查。共鉴定出10种寄生虫，分别属于线虫纲（小窄体线虫、巨头窄体线虫、海兽蛔线虫属（假蛔科）、异尖线虫属（异尖科）、粗尾线虫属（粗尾科））、绦虫纲（海豚叶槽绦虫和格里马尔迪单槽绦虫（叶槽科））、吸虫纲（具叶短腺吸虫和海豚短腺吸虫（短腺科））和甲壳纲（南极鲸虱（鲸虱科））。其中一些寄生虫物种是其宿主的新记录。尽管这些材料并非在系统的寄生虫学调查中采集，但这些发现包含了关于来自偏远海洋环境的珍稀、洄游且易危海洋野生动物寄生虫群落的宝贵新信息。
