Digital and palmar dermatoglyphic patterns were analysed for 286 male and female Bribri and Cabecar Amerindians of Chibcha ascendancy from four populations located in southeastern Costa Rica. There was no significant difference among Pacific and Atlantic Cabecar samples, with the exception of the bc and cd ridge count. However, the Bribri groups present differences for 22 features, though the largest differences are between Bribri and Cabecar Pacific populations. A comparison with other Latin-American indians evidence that dermatoglyphic patterns of Bribri and Cabecar tribes are within the expected range, but it is important to notice the high frequency of digital arcs and the low frequency of worls. The results are similar to those observed using other genetic markers in the same populations, and demonstrate the discriminable capacity of the dermatoglyphics to tribal level for taxonomic and evolutionary studies.
对来自哥斯达黎加东南部四个群体的286名具有奇布查血统的布里布里族和卡韦卡尔族美洲印第安男性和女性的指纹和掌纹图案进行了分析。除了bc和cd嵴纹计数外，太平洋地区和大西洋地区的卡韦卡尔样本之间没有显著差异。然而，布里布里族群体在22个特征上存在差异，尽管最大的差异存在于布里布里族和太平洋地区的卡韦卡尔族群体之间。与其他拉丁美洲印第安人的比较表明，布里布里族和卡韦卡尔族部落的指纹图案在预期范围内，但需要注意的是，指弧的高频率和斗形纹的低频率。结果与在同一群体中使用其他遗传标记所观察到的结果相似，并证明了指纹学在部落层面上用于分类学和进化研究的鉴别能力。
