Abstract
Abstract: The diversity of the tropical climbing salamander genus Bolitoglossa (Magnadigita) in Honduras has been underestimated historically, with 11 new species having been described in the past quarter-century. Bolitoglossa celaque is known to occur in three disjunct mountain ranges across the Lenca Highlands region of southwestern Honduras, and previous studies have independently demonstrated differences in mitochondrial genealogy and genome size between populations to the east and west of the Mejocote–San Juan Depression. Sampling from all three mountain ranges represented two genetically distinct clades: one associated with the vicinity of the type locality, Montaña de Celaque, and the second consisting of several eastern populations from the departments of Intibucá and La Paz. Distinctiveness of these two clades was further investigated and supported by analyses of morphological variation, geometric morphometrics of foot morphology, and comparative osteology. Based on congruent signals from each line of evidence, we restrict the taxon B. celaque to Montaña de Celaque and describe the eastern populations as a new species of Bolitoglossa.
摘要:洪都拉斯热带攀爬蝾螈属Bolitoglossa (Magnadigita)的多样性在过去的25年里被低估了,仅有11个新种被发现。众所周知,celaque Bolitoglossa出现在洪都拉斯西南部伦卡高地地区的三个不相交的山脉中,以前的研究已经独立地证明了Mejocote-San Juan洼地东部和西部人群在线粒体谱系和基因组大小上的差异。来自所有三个山脉的采样代表了两个遗传上不同的分支:一个与模式地点Montaña de Celaque附近有关,第二个由来自因蒂布布省和拉巴斯省的几个东部种群组成。形态学变异、足部几何形态计量学和比较骨学分析进一步研究了这两个支系的独特性。基于各证据线的一致信号,我们将B. celaque分类群限定为Montaña de celaque,并将东部种群描述为Bolitoglossa的新种。
