A redescription of Pintneriella Yamaguti, 1934 (Cestoda : Trypanorhynchaand an examination of its systematic position

摘要

Specimens of Pintneriella musculicola Yamaguti, 1934 are redescribed based on paratype material and specimens subsequently allocated to the species by its describer. The cestode species is characterised by two bothridia, a typical heteroacanthous armature with a distinctive basal swelling and basal armature, a space between hook files 1 and 1', nine hooks per principal row, no intercalary hooks and bands of hooklets or chainettes but a distinctive space on the external surface of the tentacle between hook files 9 and 9'. The strobilia is unknown. The features described indicate that Pintneriella is a valid genus within the Heteracanthoidea. Its currently known morphological features do not allow its allocation to an existing family.
