A New Species of the GenusPeriglischrus(Acari: Spinturnicidae) onLeptonycteris nivalis(Chiroptera: Phyllostomidae) From Mexico, Including a Key to Species of thevargasiSpecies Group

Abstract

Periglischrus calcariflexus new species, was found on the Greater Long-tongued bat Leptonycteris nivalis (Saussure) in Mexico. The female, male, deutonymphs, and protonymph are described and illustrated. Additionally, we evaluate the morphological variability of this species based on its geographical distribution. Considering this new species, the number of species in the vargasi species group within the genus Periglischrus increases to five; therefore, herein we include a key for the known species in the vargasi species group for the Neotropics.
