Abstract

Abstract: We evaluated the morphometric variation of wing mite Periglischrus paracaligus Herrin and Tipton, along with the distribution of their host Leptonycteris yerbabuenae Martinez and Villa, in Mexico. A total of 115 female and 96 male specimens of P. paracaligus were used to conduct linear and geometric morphometric analyses. We assessed the influence of the geographic distribution of the migratory and nonmigratory populations of its bat host species on changes in size and shape on these parasites. Both analyses revealed high intraspecific variation in P. paracaligus, but subtle geographic differentiation. None of the approaches used identified a consistent pattern that separates unambiguously migratory from nonmigratory populations. Females presented more phenotypic variation than males and UPGMA analyses showed southern and northern colonies grouped in two distinct clades. Males on the other hand showed randomly grouped colonies with no geographic concordance. Interestingly, the most differentiated colony was the north Pacific colony of Jalisco. For both, males and females, isolation by distance (IBD) was not observed. We discuss these results as a possible scenario of contact between migratory populations located in northern Mexico with nonmigratory populations in other localities in central and southern Mexico conforming to a panmictic population along with their distribution range.
