We describe Bolitoglossa qeqom sp. nov. from an isolated cloud forest in Cerro Guachmalén, Alta Verapaz, Guatemala, based on multiple lines of evidence (morphological, molecular, and biogeographic data). This region comprises a mountain ridge without previous herpetological surveys. The new species is a large salamander with uniform purplish-black coloration and is distinguished by having relatively long legs with only one costal groove between adpressed limbs, numerous maxillary teeth, few vomerine teeth, only one phalange free of webbing in digit III of feet, and a relatively short tail. It is geographically closest to its sister clade of B. lincolni + B. franklini and the xeric Chixoy river canyon appears to be the major biogeographic barrier that isolated the new taxon. The cloud forest inhabited by this species has undergone severe habitat destruction in the region and land conservation actions are urgent.
我们描述了一种来自危地马拉 Alta Verapaz 省塞罗瓜马伦的孤立云雾森林的 Bolitoglossa qeqom 新种，这是基于多种证据（形态学、分子和生物地理学数据）得出的。该地区是一条没有先前进行过爬行动物调查的山脊。这个新物种是一种大型蝾螈，通体呈均匀的深紫色到黑色，其特征是腿部相对较长，四肢并拢时只有一条肋沟，上颌有很多牙齿，犁骨齿较少，足部第三趾的一个趾节没有蹼，尾巴相对较短。它在地理上与它的姐妹群 B. lincolni + B. franklini 最为接近，而干旱的 Chixoy 河谷似乎是将新分类群隔离的主要地理障碍。这种物种栖息的云雾森林在该地区遭受了严重的破坏，因此土地保护行动迫在眉睫。
