Trypanorhyncha from sharks of southern brazilian coast: Eutetrarhynchus vooremi sp. n. and two other species parasites of Mustelus (Pisces, Triakidae). Mem. Inst. Oswaldo Cruz [online]. 1989, vol.84, suppl.4, pp.475-481. ISSN 0074-0276. http://dx.doi.org/10.1590/S0074-02761989000800083.
In the present paper, Eutetrahynchus vooremi sp. n., a cestode of the order Trypanorhyncha is proposed. The new species was recovered from sharks under the genus Mustelus (Pisces, Triakidae) and was compared to E. ruficollis, E. lineatus, E. leucomelanus, E. litocephalus and E. macrotrachelus. The main character, among others, considered to differ the species refers to the eggs filament, size of proglottids, tentacular hooks and lenght of pars postbulbosa. Two other known species are studied: Callitetrarhynchus gracilis (Rudolphi, 1819) from M. canis (Mitchill, 1815) and Nybelinia (N.) lingualis (Cuvier, 1817) from M. schmitti Springer, 1939 representing new host records.
