Abstract
Some conditions from complete dissection of hand and foot muscles of Pristimantis bogotensis (Strabomantidae) presented here have not been reported in anurans. One muscle not described before was found: the m. abductor ulnocarpalis. Muscles of the forearm, the hand, and the foot were found as exclusive characters in this species. Two minor variants (sensu Raikow et al., 1990) were identified, showing that it is important to examine hind and forelimbs of both sides of the body (left and right) in anatomical studies for detecting intraspecific variation.References
