Introduction. Sexual differences in the features of plantar dermatoglyphics are not sufficiently studied. Further development of the topic and accumulation of data on local populations are required. Materials and methods. The article presents the results of the dermatoglyphic study of the feet of 240 Moksha people (117 women and 123 men) from rural settlements of the South-Western Mordovia. The patterns of the plantar dermatoglyphics are recorded using the conventional method by [Cummins, Midlo, 1961]. Results. Few statistically significant differences in the distribution of features between males and females were found, with differences being more prominent when considering the dermatoglyphic characteristics of both feet. In the studied Mordva-Moksha group the pattern intensity of the feet is slightly higher for men than for women (by one triradius in total). The biggest sexual dimorphism (in half of the cases) is found in the frequency of the finger patterns occurrence. At the same time, the total number of deltas on ten toes does not differ significantly between sexes. Women have a greater proportion of arcs and tibial loops, and men have more whorls and complex patterns. Morphologically simple open fields at the 3rd and 4th interdigital pads, at the distal hypothenar, and at the proximal thenar are significantly more frequent in the female sample. The main plantar lines B, C, and D of women significantly more often end at the tibial fields, and of men – distally. The reverse situation is typical for the main line E. The skin ridges of the male heels are more often oriented transversely, and of female – proximally. Discussion. The comparison of sexual differences in frequencies of occurrence and mean values of patterns of plantar dermatoglyphics in the Mordva-Moksha group confirms the tendencies revealed for other populations according to the literature. The exception is some poorly studied features. Conclusion. The results of the study indicate that the papillary feet patterns are slightly different in the samples of Mordovian men and women. In general, a more complex dermatoglyphic type characterizes male feet. The most noticeable differences were found for the types of finger patterns, the directions of the main plantar lines and patterns on the 4th and 3rd interdigital pads. Trends found in the Mordovian group align with known distributions of plantar skin patterns in men and women for different populations.
