Resumen:
In the present study, we report the earliest record of Ixodes sigelos, from the Late Holocene in Argentina. The tick was recovered from an owl pellet collected within a small mammal sequence in Las Máscaras Cave, Catamarca, Argentina (27º01´12S´´, 66º44´37´´W), and dated for 990 ± 35 cal. yr before present. The tick parasitized a rodent ingested by the owl, and was identified as Eligmodontia sp. The only previous citation of I. sigelos in Argentina corresponds to a region with a more humid environment than that currently observed in Las Máscaras Cave. The present finding supports that ecological conditions about 1000 yr before present in the area were more humid than the present ones.
