A small-sized tree frog of the genus Rhacophorus is described on the basis of 18 specimens collected from three different localities on Sumatra Island, Indonesia. Rhacophorus indonesiensis sp. nov. is divergent from all other Rhacophorus species genetically and morphologically. The new species is distinguished from its congeners by a combination of: the presence of black spots on the ventral surfaces of the hand and foot webbing, an absence of vomerine teeth, a venter with a white kite-shaped marking, raised white spots on the dorsum or on the head, and a reddish brown dorsum with irregular dark brown blotches and distinct black dots. With the addition of this new species, fifteen species of Rhacophorus are now known from Sumatra, the highest number of species of this genus in the Sundaland region. However, with the increasing conversion of forest to oil palm cultivation or mining, the possibility of the extinction of newly described or as yet undiscovered species is of great concern.
基于从印度尼西亚苏门答腊岛三个不同地点采集的18个标本，描述了一种小型树蛙属（Rhacophorus）物种。印度尼西亚树蛙（Rhacophorus indonesiensis sp. nov.）在基因和形态上与所有其他树蛙属物种不同。该新物种与同属其他物种的区别在于以下特征组合：手部和足部蹼的腹面有黑点，无犁骨齿，腹部有白色风筝形斑纹，背部或头部有凸起的白色斑点，以及红棕色背部带有不规则深棕色斑点和明显的黑点。随着这一新物种的加入，苏门答腊岛目前已知有15种树蛙属物种，这是巽他群岛地区该属物种数量最多的情况。然而，随着森林越来越多地转变为油棕种植园或矿区，新描述或尚未发现的物种灭绝的可能性令人深感担忧。
