Resumen:
By the end of the 1960s, the argasid tick Ornithodoros peropteryx was
described from larval specimens collected from the bat Peropteryx macrotis in Colombia.
Since its original description, no additional record of O. peropteryx has been reported, and
its post-larval stages have remained unknown. During July 2010, 18 larvae were collected
from 9 bats (Centronycteris maximiliani), resulting in a mean infestation of 2.0 ± 2.2 ticks
per bat (range 1?8). These bats were captured in a farm in northeastern Bolivia close to
Guapore´ River in the border with Brazil. Morphological examinations of the larvae
revealed them to represent the species O. peropteryx. One engorged larva that was kept
alive in the laboratory moulted to a nymph after 9 days. Fourteen days after the larval
moulting, the nymph moulted to an adult female without taking any blood meal during the
nymphal period. This adult female was used for a morphological description of the female
stage of O. peropteryx. In addition, the larvae were used for a morphological redescription
of this stage. One larva and two legs extirpated from the adult female were submitted to
DNA extraction and PCR targeting a fragment of the mitochondrial 16S rDNA gene, which
yielded DNA sequences at least 11 % divergent from any available argasid sequenceOrnithodoros peropteryx was
