Nepenthes malayensis A.Amin, M.N.Faizal & Dome is described as a new species discovered from a montane forest in the eastern part of Peninsular Malaysia. The species is considered highly threatened since only a few individuals have been discovered within a limited area and almost all of them grow on humus-covered boulders scattered in the summit region. Due to a slight resemblance to N. sanguinea Lindl., it was initially thought to be of an allied form; however, anatomy, morphological and molecular analyses have established N. malayensis as a distinct taxon. A diagnosis, description, figures and preliminary conservation status of the species are provided in this article.

马来猪笼草A.Amin，MNFaizal和Dome被描述为从马来西亚半岛东部山地森林中发现的新物种。该物种被认为是高度威胁物种，因为在有限的区域内仅发现了少数个体，几乎所有人都生长在散布在山顶地区的腐殖质覆盖的巨石上。由于与南几内亚猪笼草略有相似，最初被认为是盟军形式。然而，解剖学，形态学和分子分析已将马来西亚猪笼草确立为独特的分类单元。本文提供了该物种的诊断，描述，数字和初步保存状态。
