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).
