29. Ixodes ca. boliviensis Neumann, 1904 View in CoL .

New record: Victoria: (1F, LAFC000484) Ejido Santa Ana, Heteromys irroratus Grey.

Distribution: Sierra Madre Oriental Province.

Note: The type specimens of I. boliviensis were collected in Bolivia ( Cochabamba Department) and described by Neumann (1904). Ixodes boliviensis was referred to in some Central and South American countries as Ixodes bicornis ; however, Kohls (1956) synonymized Ixodes bicornis with I. boliviensis , while Camicas et al. (1998) considered I. boliviensis as a synonym of I. diversifossus . Based on the above, a comparison between the Mexican and Bolivian species should be made. The comparison should also include the types of Ixodes diversifossus Neumann, 1899 and Ixodes bicornis Neumann, 1906 ( Guglielmone et al. 2023). Our specimen was determined as I. ca. boliviensis ; however, this specimen presented some morphological variations (differences in the punctations on the scutum and shape of the spurs of coxa I) with respect to the diagnosis referred to in Guzmán-Cornejo and Robbins (2010). Furthermore, based on the comparison of a partial sequence of the 16S rRNA gene obtained from this specimen, it was only 98% similar to I. boliviensis (GenBank accession no. OP47070.1 (Moreira-Soto et al. 2022).
