摘要本文报道了智利新记录的蒙坦丝线虫Histiotus montanus和智利的新记录线虫Histiotus laephtis。对回声定位叫声的形态测量和分析证实了物种之间的差异。与其他Histiotus物种相比，Histiotus montanus有更小的前臂(49.7±0.8vs.51.7±0.4 mm)和更黑和更短的耳朵；后者有淡黄色的皮毛。声学分析表明种间有显著差异：赤眼蜂的脉冲较短(1.3±0.4比3.6±2.6毫秒)，起始频率和峰值频率较低(起始频率38.2±2.6比46.4±4.6千赫；峰值频率30.4±3.7比32.1±2.2千赫)。这些发现使智利北部的塔拉帕卡地区成为该国蝙蝠种类最多样化的地区。此外，这些结果使该国已知的蝙蝠种类总数增加到13种。
Abstract We report new distributional records for Histiotus montanus and first records of Histiotus laephotis for Chile. Morphological measurements and analyses of echolocation calls confirm the differences between the species. Histiotus montanus has a smaller forearm (49.7±0.8 vs. 51.7±0.4 mm) and darker and shorter ears than H. laephotis; the latter has a yellowish fur in contrast to other Histiotus species. Acoustic analyses showed significant differences between the species: H. laephotis have shorter pulses (1.3±0.4 vs. 3.6±2.6 ms), with lower start and peak frequencies (start frequency 38.2±2.6 vs. 46.4±4.6 kHz; peak frequency 30.4±3.7 vs. 32.1±2.2 kHz) than H. montanus. These findings place the Tarapacá region of northern Chile as the most diverse in terms of bat species in the country. Furthermore, these results increase the total number of bat species known to occur in the country to 13.
