Revision of the genus Syncuaria Gilbert, 1927 (Nematoda: Acuarioidea)
Syncuaria Gilbert, 1927 is revised and Skrjabinocara Kurashvili, 1940 placed in synonymy with it. Nine species are recognized: S. ciconiae Gilbert, 1927 (type species); S. buckleyi (Ali, 1957) n. comb.; S. decorata (Cram, 1927); S. longialula Wang, 1976; S. leptoptili (Gedoelst, 1916) (=S. parvepapillata Macko, 1962a, 1962b); S. bressoui Gretillat, 1970; S. hargilae (Baylis and Daubney, 1923); S. diacantha Petter, 1961; and S. squamata (Linstow, 1883) n. comb. Redescriptions of the latter five species are provided. Six other species are regarded as species inquirendae: S. calcarata (Molin, 1860), S. contorta (Molin, 1858), S. longeornata (Molin, 1860), S. rostombekovi (Kurashvili, 1940) n. comb., S. ardeae (Smith, Fox and White, 1908), and S. sturni (Ozerskaya, 1927). Syncuaria longevaginata (Molin, 1860) is transferred to Desportesius, resulting in D. longevaginatus (Molin, 1860) n. comb. Syncuaria squamata was found in 11 of 18 young of the year double-crested cormorants (Phalacrocorax a. auritus (Lesson)) from Lake Erie, Ontario, Canada, indicating that transmission of this species occurs on the breeding ground of its final host.
