[Studies of the epidermal pattern system of the palms and soles of the howler monkeys (Alouatta) (author's transl)].
The epidermal pattern frequencies and pattern intensity values of the palms and soles are described for 110 male and 80 female howler monkeys (genus Alouatta) including the species A. belzebul, A. seniculus, A. caraya and A. villosa. Interspecific comparisons are made and obvious sex and side differences are noted. The plantar surface tends to show greater interspecific variability than does the palmar surface. A. caraya is possibly the most divergent species of the genus. Comparison of the results with those for Ateles and Lagothrix confirms the aberrant position of Ateles arachnoides.
