Abstract

Falcaustra batrachiensis n. sp. (Ascaridida, Kathlaniidae) from the large intestine of Nyctimystes cheesmani (Anura, Hylidae) is described and illustrated. Falcaustra batrachiensis represents the fifth Australo-Papuan species assigned to the genus and is distinguished from other Australo-Papuan species by the distribution pattern of the caudal papillae (8 precloacal, 2 adcloacal, 6 postcloacal, and 1 median), length of spicules (1.4-1.6 mm) and presence of pseudosuckers (5 or 6). Nyctimystes cheesmani was found to harbor 7 additional species of Nematoda, adults of Cosmocerca novaeguineae, Maxvachonia ewersi, Meteterakis crombiei, Physalopteroides milnensis, Pseudorictularia dipsarilis, Seuratascaris numidica, larvae in cysts of Abbreviata sp., and 1 species of Acanthocephala, Acanthocephalus bufonis. Nyctimystes cheesmani represents a new host record for each of these helminth species.

摘要

描述并图示了来自切斯曼氏夜眼蛙（无尾目，雨蛙科）大肠内的巴氏蛙 Falcaustra batrachiensis n. sp.（蛔目，卡特拉蛔科）。巴氏蛙 Falcaustra batrachiensis 是该属的第五个澳大拉西亚 - 巴布亚物种，与其他澳大拉西亚 - 巴布亚物种的区别在于尾乳突的分布模式（泄殖腔前 8 个，泄殖腔旁 2 个，泄殖腔后 6 个，中间 1 个）、交合刺长度（1.4 - 1.6 毫米）以及假吸盘的存在（5 个或 6 个）。发现切斯曼氏夜眼蛙还寄生于另外 7 种线虫，即新几内亚科斯莫丝虫、埃氏马克瓦线虫、克氏梅泰特拉线虫、米尔恩氏类泡翼线虫、迪普萨里假瑞氏线虫、努米底亚苏腊塔线虫的成虫，缩写属线虫囊肿内的幼虫，以及 1 种棘头虫，即蟾蜍棘头虫。切斯曼氏夜眼蛙是这些蠕虫物种各自的新宿主记录。
