The Rengma Nagas are one of the major Mongoloid tribal populations in the North-Eastern state of Nagaland in India. Population variation and sexual dimorphism in respect of finger dermatoglyphic characteristics in 207 adult individuals (104 males and 103 females) are reported in this present context. Frequency distribution of finger pattern types in different digits (both left and right sides combined) showed that whorls were the most prevalent patterns among both males (52.19%) and females (55.69%), followed by loops (47.70% in males and 42.81% in females). Significant sex differences in Dankmeijer Index (t = 1.47; p < 0.0001) and finger wise variations of total finger ridge count (TFRC) and absolute finger ridge count (AFRC) in both the sexes were recorded. However, in cases of the frequencies of finger dermatoglyphic pattern types, Pattern Intensity Index in fingers, TFRC and AFRC no significant sex differences were observed.
伦马那加人是印度东北部那加兰邦主要的蒙古人种部落群体之一。本文报道了207名成年人（104名男性和103名女性）手指皮肤纹理特征方面的群体变异和性别二态性。不同手指（左右两侧合并）的指纹类型频率分布表明，在男性（52.19%）和女性（55.69%）中，涡纹是最常见的指纹类型，其次是箕纹（男性为47.70%，女性为42.81%）。记录到两性在丹克迈耶指数（t = 1.47；p < 0.0001）以及总指嵴数（TFRC）和绝对指嵴数（AFRC）的手指差异方面存在显著的性别差异。然而，在手指皮肤纹理图案类型的频率、手指图案强度指数、TFRC和AFRC方面，未观察到显著的性别差异。
