Resumen:
A new species, Ornithodoros microlophi (Acari: Argasidae), belonging to the subgenus Alectorobius is
described from larvae collected on the lizards Microlophus atacamensis (Donoso-Barros, 1966) andOrnithodoros microlophi (Acari: Argasidae), belonging to the subgenus Alectorobius is
described from larvae collected on the lizards Microlophus atacamensis (Donoso-Barros, 1966) andMicrolophus atacamensis (Donoso-Barros, 1966) and
Microlophus quadrivittatus (Tschudi, 1845) (Squamata: Tropiduridae) in continental and insular localities
from northern Chile. Larvae of O. microlophi can be distinguished from other Neotropical species of
the genus Ornithodoros by a combination of the following characters, namely 10 pairs of ventral setae,
venter with 6 pairs of sternal setae, dorsal plate pyriform, 19?21 pairs of dorsal setae (typically 20), 13
pairs are dorsolateral and 7 pairs are central, and hypostome with dental formula 4/4 in medial portion
and apex pointed. Phylogenetic analysis of 16S rDNA sequences suggests that O. microlophi represents
an independent lineage within Neotropical species of the Argasidae(Tschudi, 1845) (Squamata: Tropiduridae) in continental and insular localities
