Nepenthes batik G.Lim, Golos, Mey, Wistuba & A.S.Rob. is described from Fraser’s Hill in the Titiwangsa Range of Peninsular Malaysia, where it inhabits montane forests at c. 1300–1500 m elevation. A putative close relative of N. ramispina Ridl., the species can be distinguished by its more diminutive overall size, and particularly by consistent differences in phyllode (‘lamina’) morphology, lower pitcher shape, tendril to pitcher length ratio, spur morphology, and lid gland size and distribution. As a secondary but nonetheless helpful characteristic, all known populations of N. batik consistently differ from N. ramispina in terms of pitcher colouration. The conservation status and nearest affinities of N. batik are assessed, and an updated key to the Nepenthes species of the southern Titiwangsa Range provided. Finally, the distribution of N. ramispina is clarified based on field observations and a thorough re-examination of existing herbarium material.
