Abstract

A new species of Günther, 1896 is described from Yunnan Province, China, based on morphological and molecular evidence. Morphologically, is distinguished from its congeners by a combination of the following diagnostic characters: body size large; adult males with keratinized spines on chest, belly, lateral body, posterior dorsum, buttocks, outer side of the fore limbs, the inner metacarpal tubercle, fingers I and II, and upper eyelids; no spines on the inner side of the lower and upper arm; forelimbs strongly hypertrophied in adult males; anterior dorsum skin smooth; dorsolateral folds absent; finger I longer than finger II; webbing deeply incurved between tips of toes; present outer metacarpal tubercle and absent outer metatarsal tubercle. The new species is separated from all other congeners by uncorrected genetic distances ranging from 5.2% to 7.3% based on mitochondrial 16S rRNA gene and ranging from 3.9% to 7.6% based on mitochondrial 12S rRNA gene.

摘要

基于形态学和分子证据，描述了一种来自中国云南省的1896年的冈瑟新物种。在形态上，它与同属其他物种的区别在于以下一系列诊断特征的组合：体型大；成年雄性在胸部、腹部、身体侧面、背部后部、臀部、前肢外侧、内侧掌突、第一和第二指以及上眼睑有角质化棘刺；上臂和下臂内侧无棘刺；成年雄性前肢强烈肥大；背部前部皮肤光滑；无背外侧褶皱；第一指长于第二指；趾尖之间的蹼深深弯曲；有外侧掌突且无外侧跖突。基于线粒体16S rRNA基因，该新物种与所有其他同属物种的未校正遗传距离在5.2%至7.3%之间，基于线粒体12S rRNA基因，遗传距离在3.9%至7.6%之间。
