Chabaudacuaria n. g. is erected, as monotypic, for C. multispinosa (Pérez Vigueras, 1938) n. comb. (Spirurida: Acuariidae) [syns Cheilospirura multispinosa Pérez Vigueras, 1938; Acuaria multispinosa (Pérez Vigueras, 1938) Yamaguti, 1961]. This species, a parasite of various ardeid birds, is redescribed by means of light and scanning electron microscopy based on material from great blue herons Ardea herodias L. and yellow-crowned night herons Nyctanassa violacea (L.) in Florida, USA. Chabaudacuaria n. g. resembles Acuaria Bremser, 1811, Cheilospirura Diesing, 1861, Skrjabinocerca Schikhobalova, 1930 and Xenocordon Mawson, 1982 in its straight cordons which do not anastomose. However, it can be distinguished from them by the didelphic-prodelphic uterus and the absence of caudal alae in the males. In the pattern of its cordons (consisting of a row of plates and a longitudinal ridge) and the absence of an area rugosa, the new genus is similar to Chevreuxia Seurat, 1918, Syncuaria Gil'bert, 1927, Aviculariella Wehr, 1931, Skrjabinocara Kurashvili, 1940, Decorataria Sobolev, 1949 and Desportesius Chabaud & Campana, 1949, which are characterised by anastomosing cordons. The didelphic-prodelphic female reproductive system of Chabaudacuaria is intermediate between the didelphic-amphidelphic uterus of Chevreuxia and the monodelphic-prodelphic uterus of Syncuaria, Aviculariella, Skrjabinocara, Desportesius and Decorataria. Therefore, the straight and non-anastomosing cordons are considered to be autapomorphic for Chabaudacuaria.
新属Chabaudacuaria被建立，为单型属，用于包含多刺Chabaudacuaria（Pérez Vigueras，1938年）新组合（旋尾目：尖尾科）[同物异名：多刺唇旋尾线虫Cheilospirura multispinosa Pérez Vigueras，1938年；多刺尖尾线虫Acuaria multispinosa (Pérez Vigueras, 1938) Yamaguti，1961年]。该物种是多种鹭科鸟类的寄生虫，基于来自美国佛罗里达州大蓝鹭Ardea herodias L.和黄冠夜鹭Nyctanassa violacea (L.)的材料，通过光学显微镜和扫描电子显微镜对其进行了重新描述。新属Chabaudacuaria在其不吻合的直索方面类似于1811年的Bremser的Acuaria属、1861年的Diesing的Cheilospirura属、1930年的Schikhobalova的Skrjabinocerca属以及1982年的Mawson的Xenocordon属。然而，它可以通过双宫 - 前双宫型子宫以及雄性无尾翼与它们区分开来。在其索的模式（由一排板和一条纵向脊组成）以及无皱区方面，新属类似于1918年的Seurat的Chevreuxia属、1927年的Gil'bert的Syncuaria属、1931年的Wehr的Aviculariella属、1940年的Kurashvili的Skrjabinocara属、1949年的Sobolev的Decorataria属以及1949年的Chabaud和Campana的Desportesius属，这些属的特征是索相互吻合。Chabaudacuaria的双宫 - 前双宫型雌性生殖系统介于Chevreuxia的双宫 - 双宫型子宫和Syncuaria、Aviculariella、Skrjabinocara、Desportesius和Decorataria的单宫 - 前双宫型子宫之间。因此，直的且不吻合的索被认为是Chabaudacuaria的自近裔性状。
