New records of the spider Chibchea salta Huber 2000 (Araneae, Pholcidae) from northwestern Argentina are provided, and the potential range of this species is modeled. Two presence-only methods, Maxent and Bioclim, were run using 19 bioclimatic parameters at a resolution of 30 arc seconds. The climatic profile of C. salta is described, and the relative importance of the bioclimatic variables is explored. Temperature variables proved to be more decisive to the final range shape. The range predicted with Maxent is slightly larger than with Bioclim, but the latter appears to be more sensitive to the record set bias. Both methods performed well, resulting in predictive ranges consistent with the yungas ecoregion. These results provide an initial insight into the bioclimatic tolerance of C. salta, and by identifying potential areas with no records, such as the sierras on the Salta-Jujuy border, they also help in identifying sites for future sampling efforts.
提供了来自阿根廷西北部的蜘蛛 Chibchea salta Huber 2000（Araneae，Pholcidae）的新记录，并对该物种的潜在范围进行了建模。使用 30 弧秒分辨率的 19 个生物气候参数运行了两种仅存在方法，最大熵和生物气候。描述了 C. salta 的气候概况，并探讨了生物气候变量的相对重要性。温度变量被证明对最终范围形状更具决定性。最大熵预测的范围略大于生物气候，但后者似乎对记录集偏差更敏感。两种方法都表现良好，预测范围与 yungas 生态区一致。这些结果初步了解了 C. salta 的生物气候耐受性，并通过确定没有记录的潜在区域，例如萨尔塔-胡胡伊边境的山脉，它们还有助于确定未来采样工作的地点。
