The present report deals with digital and palmar dermatoglyphics of a sample of 98 Chorote indians, collected in the north of Argentina, in the Gran Chaco region. Bimanual dimorphism was observed in males and females, both in finger and in palmar variables. Significant differences between sexes appear only in digital ridge counts and in the combined incidence of the four pattern types the Chorote, in general, show low sexual dimorphism. Univariate comparisons carried out with other tribes of the Gran Chaco (Chiriguano, Pilagá, Mataco, and Toba) indicate statistically significant differences between these and the Chorote, both in males and females. The greatest differences were found in relation to the Mataco, who belong to the same linguistic family as the Chorote. Probable explanations for these differences are proposed.
本报告涉及对98名乔罗特印第安人的样本进行的数字和手掌皮纹学研究，这些样本采集于阿根廷北部的大查科地区。在男性和女性中均观察到双手二态性，无论是手指变量还是手掌变量。性别之间的显著差异仅出现在指嵴计数以及四种花纹类型的综合发生率上，总体而言，乔罗特人表现出较低的性别二态性。与大查科地区的其他部落（奇里瓜诺、皮拉加、马塔科和托巴）进行的单变量比较表明，这些部落与乔罗特人在男性和女性中均存在统计学上的显著差异。与马塔科人（他们与乔罗特人属于同一语系）相比，差异最为显著。文中提出了这些差异的可能解释。
