Rhinobatos typus and Rhynchobatus djiddensis were collected from Heron Island, Australia and examined for monocotylid parasites. Specimens of Neoheterocotyle rhinobatidis (Young, 1967) Chisholm, 1994 and N. rhynchobatis (Tripathi, 1959) Chisholm, 1994 were collected from the gills of Rhinobatos typus. This represents both a new host and new locality record for N. rhynchobatis. Neoheterocotyle bychowskyi (Timofeeva, 1981) Chisholm, 1994, N. nagibinae (Timofeeva, 1981) Chisholm, 1994 and N. rhinobatis (Pillai & Pillai, 1976) n. comb. were identified from the gills of Rhynchobatus djiddensis from Australia and are all new locality records. We consider N. djiddensis (Pillai & Pillai, 1976) n. comb. a species inquirenda and synonymise N. trilobata Timofeeva, 1981 with N. rhinobatis. Therefore, there are 7 valid species in the genus, including N. bychowskyi, N. forficata, N. inpristi, N. nagibinae, N. rhinobatidis, N. rhinobatis and N. rhynchobatis. The larvae of N. rhinobatis and N. rhynchobatis are described and the anterior glands of the larvae are related to those of the adults. The development of the male copulatory organ of N. rhinobatidis is described. Host-specificity and geographic range of the genus are also discussed and a key to species is provided.
犁头鳐(Rhinobatos typus)和吉氏前口蝠鲼(Rhynchobatus djiddensis)采自澳大利亚赫伦岛,并对其进行单殖吸虫寄生虫检查。从犁头鳐的鳃上采集到了新异杯虫属(Neoheterocotyle)的鼻新异杯虫(Neoheterocotyle rhinobatidis (Young, 1967) Chisholm, 1994)和吻新异杯虫(N. rhynchobatis (Tripathi, 1959) Chisholm, 1994)标本。这代表了吻新异杯虫的新宿主和新地点记录。从澳大利亚吉氏前口蝠鲼的鳃上鉴定出了比氏新异杯虫(Neoheterocotyle bychowskyi (Timofeeva, 1981) Chisholm, 1994)、纳氏新异杯虫(N. nagibinae (Timofeeva, 1981) Chisholm, 1994)和鼻新异杯虫(N. rhinobatis (Pillai & Pillai, 1976) n. comb.),这些均为新地点记录。我们认为吉氏新异杯虫(N. djiddensis (Pillai & Pillai, 1976) n. comb.)是一个有待研究的物种,并将三叶新异杯虫(N. trilobata Timofeeva, 1981)同义于鼻新异杯虫。因此,该属有7个有效物种,包括比氏新异杯虫、叉形新异杯虫、无鳍新异杯虫、纳氏新异杯虫、鼻新异杯虫、鼻新异杯虫和吻新异杯虫。描述了鼻新异杯虫和吻新异杯虫的幼虫,并将幼虫的前腺与成虫的前腺进行了关联。描述了鼻新异杯虫雄性交配器官的发育。还讨论了该属的宿主特异性和地理分布范围,并提供了物种检索表。
