Two furcocercariae respectively Colylurus brevis Dubois et Rausch, 1950 from Segmentina nitida and Apatemon (A.) minor Yamaguti, 1933 from Gyraulus acronicus were studied and identified morphologically. Ciliary papillae distribution was studied after staining with silver nitrate solution and compared with that of cercariae known in the same genus. Colylurus brevis was compared to Cotylurus lutzi Basch, 1969 and Cotylurus sp. Kruger, 1978. Apatemon (A.) minor was compared to Apatemon sp. Kruger, 1978, Apatemon graciliformis Szidat, 1928, and Cercaria 1 Richard, 1971. Cercariae of the genus Cotylurus and Apatemon were easily identified from the number and distribution of acetabular papillae: 4 SI + 6 SII in Cotylurus and 3 SI + 3 SII in Apatemon. These characteristics further enabled the identification of a cercaria belonging to the genus Diplostomum since all the carcariae studied in this genus have 3 SI + 6 SII.
对分别来自光壳椎实螺的短叉双睾吸虫（Colylurus brevis Dubois et Rausch，1950）和来自凸旋螺的微小艾氏吸虫（Apatemon (A.) minor Yamaguti，1933）的两种叉尾尾蚴进行了形态学研究和鉴定。用硝酸银溶液染色后研究了纤毛乳头的分布，并与同属已知尾蚴的分布进行了比较。将短叉双睾吸虫与1969年的卢氏杯殖吸虫（Cotylurus lutzi Basch）和1978年的克鲁格杯殖吸虫（Cotylurus sp. Kruger）进行了比较。将微小艾氏吸虫与1978年的克鲁格艾氏吸虫（Apatemon sp. Kruger）、1928年的细长艾氏吸虫（Apatemon graciliformis Szidat）以及1971年的理查德尾蚴1（Cercaria 1 Richard）进行了比较。杯殖吸虫属和艾氏吸虫属的尾蚴可根据腹吸盘乳头的数量和分布轻松鉴定：杯殖吸虫属为4个I型+6个II型，艾氏吸虫属为3个I型+3个II型。这些特征进一步有助于鉴定属于双口吸虫属的尾蚴，因为该属所有研究的尾蚴均为3个I型+6个II型。
