discussion
Comments: The characteristics observed in the specimens collected in Yucatán agreed with descriptions given by Miyazaki (1991) and Fitte et al. (2017 a), i. e. scolex 146 long by 215 – 217 wide, with unarmed rostellum and four suckers 90 – 97 long by 78 – 90 wide; three testicles separated in two groups by female gonads; and eggs 58 – 73 long by 45 – 63 wide without polar filaments. In México, H. diminuta has been recorded from R. rattus in Michoacán (Tay Zavala et al. 1999), R. norvegicus in México City (Caballero y Caballero 1939; Zerecero 1943), Michoacán (Hierro-Huerta 1992; Tay Zavala et al. 1999), and Tabasco (Cigarroa-Toledo et al. 2017), Hodomys alleni (Merriam) in Colima (Miyazaki et al. 1980), and Peromyscus difficilis (Allen) in Hidalgo (Carmona-Huerta 1994). In Yucatán, this species was previously reported from M. musculus in Opichén (134 km to Xkalakdzonot) and also from R. rattus in two localities in Mérida (121 – 124 km to Xkalakdzonot) and Opichén (Panti-May et al. 2017).
