Paraliga charadrii n. sp. (Dilepididae) is described from the small intestine of the semipalmated plover Charadrius semipalmatus (Charadriidae) collected from the Bay of Fundy, New Brunswick, Canada. The new species is distinguished from the type species Paraliga oophorae (Belopolskaya, 1971) Belopolskaya and Kulachkova, 1973, by having 2 identical rows of rostellar hooks and fewer testes and from the more similar Paraliga celermaturus (Deblock and Rosé, 1962) Bona, 1994, by its shorter and less robust rostellar hooks (18-19 microm vs. 24-26 microm). This is the first record of a species of Paraliga in the New World. Paraliga charadrii n. sp. was present in semipalmated plovers collected on their breeding grounds in Manitoba, on staging grounds in the Bay of Fundy, during southward migration, on wintering grounds in Venezuela, and on spring staging grounds at Delaware Bay, during northward migration, suggesting that transmission is ubiquitous.
半蹼鸻双叶绦虫新种（双叶科）是从加拿大新不伦瑞克芬迪湾采集的半蹼鸻（鸻科）小肠中发现的。该新物种与模式种卵巢双叶绦虫（别洛波尔斯卡娅，1971年）别洛波尔斯卡娅和库拉奇科娃，1973年不同，其具有两排相同的吻钩且睾丸较少；与更为相似的敏捷双叶绦虫（德布洛克和罗塞，1962年）博纳，1994年不同，其吻钩较短且不那么粗壮（18 - 19微米对24 - 26微米）。这是双叶绦虫属物种在新大陆的首次记录。半蹼鸻双叶绦虫新种存在于在马尼托巴繁殖地采集的半蹼鸻、在芬迪湾停歇地的、南迁期间、在委内瑞拉越冬地的以及北迁期间在特拉华湾春季停歇地的半蹼鸻体内，这表明其传播无处不在。
