The morphology of the two little-known fish cestodes of the genus Khawia Hsü, 1935, K. rossittensis (Szidat, 1937) and K. parva (Zmeev, 1936) from cyprinid fishes, were studied on the basis of newly collected specimens from goldfish Carassius auratus auratus (L.) and museum specimens, respectively. This paper provides the first detailed species diagnosis for K. rossittensis from Slovakia, which is compared with specimens from different geographical regions and K. parva, a somewhat similar Far Eastern species from the same host. The two species differ in scolex morphology, anterior extent of the vitelline follicles, shape of the ovary and size of the eggs. Based on these differences, K. rossittensis and K. parva are considered to be separate taxa. K. parva, listed among the "species incertae sedis" by Mackiewicz (1972) and even within Caryophyllaeus Gmelin, 1790 by Schmidt (1986), should be considered a valid species of Khawia. The results support the previous conclusions of Kulakovskaya (1961), Dubinina (1971) and Protasova et al. (1990).
基于分别从金鱼（Carassius auratus auratus (L.)）新采集的标本和博物馆标本，对1935年许氏（Hsü）建立的Khawia属两种鲜为人知的鱼类绦虫，即罗斯氏Khawia rossittensis (Szidat, 1937) 和微小Khawia parva (Zmeev, 1936) 的形态进行了研究。本文首次对来自斯洛伐克的罗斯氏Khawia rossittensis进行了详细的物种诊断，并将其与来自不同地理区域的标本以及微小Khawia parva（一种来自同一宿主的、有些相似的远东物种）进行了比较。这两个物种在头节形态、卵黄滤泡的前端范围、卵巢形状和卵的大小方面存在差异。基于这些差异，罗斯氏Khawia rossittensis和微小Khawia parva被认为是不同的分类单元。微小Khawia parva，被马基维茨（Mackiewicz，1972年）列为“待定物种”，甚至被施密特（Schmidt，1986年）归入1790年的格梅林（Gmelin）的Caryophyllaeus属内，应被视为Khawia属的一个有效物种。研究结果支持了库拉科夫斯卡娅（Kulakovskaya，1961年）、杜比宁娜（Dubinina，1971年）和普罗塔索娃等人（Protasova et al.，1990年）之前的结论。
