title: Redescription of Ornithodoros dyeri (Ixodida: Argasidae) based on morphologic and molecular data.
abstract: Larvae, nymphs and adults of the cave dwelling tick Ornithodoros dyeri, collected in 3 Mexican states, were studied using morphological and molecular methods. The adults and nymphs were characterized by an elongated body in proportion to the width and a dorsum bounded by two contiguous ridges and one third ridge (inner) that was incomplete on each side. The larvae of this species have 14 pairs of dorsal setae, a venter 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 a capsule of Halleŕs organ with reticulations. Based on a maximum likelihood analysis of the sequences of a fragment of approximately 414bp of the mitochondrial 16S rRNA gene, we showed that O. dyeri represents an independent lineage within neotropical species of the Argasidae. The bat species Mimon cozumelae and Peropteryx macrotis represents a new host record for this argasid.
