During a parasitological survey of teleosts and elasmobranchs in the Argentine Sea, 3 species of eutetrarhynchids were collected from the batoids Myliobatis goodei Garman and Psammobatis bergi Marini, and the shark Mustelus schmitti Springer. The specimens collected from Mu. schmitti were identified as Dollfusiela vooremi (Sπo Clemente et Gomes, 1989), whereas the specimens from My. goodei and Ps. bergi resulted in new species of Dollfusiella Campbell et Beveridge, 1994 and Parachristianella Dollfus, 1946, respectively. Dollfusiella taminii sp. n. from Ps. bergi is characterised by a distinct basal armature with basal swelling and a heteroacanthous homeomorphous metabasal armature with 7-9 falcate hooks per principal row. Parachristianella damiani sp. n. from My. goodei lacks a distinct basal armature, having 2-3 initial rows of uncinate hooks, a heteroacanthous heteromorphous metabasal armature with the first principal row of small hooks, followed by rows with 10-14 large hooks. This is the first record of Parachristianella in the southwestern Atlantic. The amended description of D. vooremi includes the detailed description of the tentacular armature, including SEM micrographs of all tentacular surfaces. This species is characterised by a basal armature consisting of rows of uncinate and falcate hooks, a basal swelling and a metabasal armature with billhooks on the antibothrial surface and uncinate hooks on the bothrial surface. The scolex peduncle of D. vooremi is covered with enlarged spinitriches. This species is restricted to carcharhiniform sharks, since the report of D. vooremi in Sympterygia bonapartii Müller et Henle off Bahia Blanca (Argentina) is dubious.
在对阿根廷海域硬骨鱼和软骨鱼进行的寄生虫学调查中，从鲼形目鱼类古氏蝠鲼（Myliobatis goodei Garman）、贝氏黄魟（Psammobatis bergi Marini）以及施氏鼬鲨（Mustelus schmitti Springer）体内采集到了3种真四吻绦虫科物种。从施氏鼬鲨体内采集到的标本被鉴定为沃氏多尔夫绦虫（Dollfusiela vooremi，Sπo Clemente et Gomes，1989），而从古氏蝠鲼和贝氏黄魟体内采集到的标本分别被鉴定为1994年坎贝尔和贝弗里奇描述的多尔夫绦虫属新物种以及1946年多尔夫斯描述的副克里斯蒂绦虫属（Parachristianella）新物种。来自贝氏黄魟的塔氏多尔夫绦虫新种（Dollfusiella taminii sp. n.）的特征是具有明显的基部小刺，基部有肿胀，以及异棘同形的后基部小刺，每排主小刺有7 - 9个镰状钩。来自古氏蝠鲼的达米亚尼副克里斯蒂绦虫新种（Parachristianella damiani sp. n.）没有明显的基部小刺，有2 - 3排起始的钩状小刺，异棘异形的后基部小刺，第一排主小刺为小钩，随后几排有10 - 14个大钩。这是副克里斯蒂绦虫属在西南大西洋的首次记录。对沃氏多尔夫绦虫的修订描述包括触手小刺的详细描述，以及所有触手表面的扫描电子显微镜照片。该物种的特征是基部小刺由钩状和镰状钩排成行，基部有肿胀，后基部小刺在反腹面有喙状钩，在腹面有钩状钩。沃氏多尔夫绦虫的头节柄覆盖着增大的棘状刚毛。该物种仅限于真鲨目鲨鱼，因为在布兰卡港（阿根廷）附近的波拿巴氏角鲨（Sympterygia bonapartii Müller et Henle）体内发现沃氏多尔夫绦虫的报告存疑。
