tLarvae, nymphs and adults of the cave dwelling tick Ornithodoros dyeri, collected in 3 Mexican states, werestudied using morphological and molecular methods. The adults and nymphs were characterized by anelongated body in proportion to the width and a dorsum bounded by two contiguous ridges and one thirdridge (inner) that was incomplete on each side. The larvae of this species have 14 pairs of dorsal setae, aventer body with nine pairs of setae plus a posteromedian; a moderately large, dorsal plate and piriform,a hypostome arising from a relatively short, subtriangular median extension of the basis capituli, and acapsule of Haller´ıs organ with reticulations. Based on a maximum likelihood analysis of the sequencesof a fragment of approximately 414 bp of the mitochondrial 16S rRNA gene, we showed that O. dyerirepresents an independent lineage within neotropical species of the Argasidae. The bat species Mimoncozumelae and Peropteryx macrotis represents a new host record for this argasid.
