discussion
Comments: Each cyst contained one metacestode, which measured from 4 mm to 140 mm prior fixation. The specimens collected in this study showed characteristics which agreed with descriptions given by Jones & Pybus (2001) and Fitte et al. (2017 b), i. e. scolex with four suckers 692 – 877 in diameter and rostellum with double alternative crowns of 17 – 19 hooks each, longer hooks 377 – 410 in length and smaller hooks 221 – 253 in length. In México, H. taeniaeformis has been reported from M. musculus in México City (García-Prieto et al. 2012), R. rattus in Hidalgo (Pulido-Flores et al. 2005), R. norvegicus in México City (Caballero y Caballero 1939) and Michoacán (Hierro-Huerta 1992), and Sigmodon hispidus Say & Ord in Nuevo León (Gutiérrez-González 1980). In Yucatán, this cestode has been previously recorded from M. musculus and R. rattus in three localities in Mérida (116 – 124 km to Xkalakdzonot and 56 – 59 km to Paraíso) and in Opichén (30 km to Paraíso) (Rodríguez- Vivas et al. 2011; Panti-May et al. 2015, 2017). This is the first record of H. taeniaeformis from S. toltecus in México.
