Another essential character is the presence of 9 hook-like spines at the basis of the cirrus. The pseudoscolex and cirrus seem to attain...
The description of Fimbriaria teresae sp. n. is given. It differs from the 5 hitherto-described species of the genus Fimbriaria in having 7-10 genital primordia in every segment (one complex of proglottids), as well as deeply-situated genital atria giving the impression of the presence of proglottids. The cirrus pouch, the cirrus and the copulatory part of the vagina of F. teresae sp. n., are also...
