Abstract:
This study updates the distribution and phylogenetic position of Ornithodoros (Pavlovskyella) nicollei in Mexico through new occurrence records, morphological identification, and the first molecular data for the species. A total of 171 specimens were collected from seven localities across five Mexican states: Sinaloa, State of Mexico, Puebla, Oaxaca, and Chiapas. Morphological identification was based on diagnostic characters consistent with previous descriptions of the species. For molecular characterization, a 475 bp fragment of the mitochondrial 16S rDNA gene was sequenced, showing 83.09-84.26% identity with other Neotropical members of the subgenus Pavlovskyella. Phylogenetic analysis placed O. (P.) nicollei within the Neotropical Pavlovskyella clade, where it represents the northernmost known member. These results expand the known distribution of the species in Mexico and provide the first molecular framework for its phylogenetic placement and biogeographic significance.
