Banded langurs, , are distributed in southern Peninsular Malaysia, , Johor and its borders including Singapore. It has been estimated that there are only < 250 mature individuals of in Malaysia and Singapore, and the species is currently considered Critically Endangered. The dietary information of and even other closely related species has rarely been reported. This study, therefore, aimed to describe the species dietary habits and discuss interaction between their feeding behaviour and its surrounding. This study was conducted from February to November 2018, with 15 sampling days each month. We collected a total of 186 sighting hours, using a scan sampling method with 10-min intervals, on a five-langur focal group. We identified 29 species based on 47 items consumed by the banded langur, mostly young leaves (51%) followed by fruits (45%), and flowers (3.8%). The study group spent slightly more time consuming non-cultivated plants but relied on cultivated plants for the fruits. Over 75% of fruit feeding involved consuming cultivar plants; in most cases (73%), they ate only the pulp, not the seeds. Since the cultivated plants were planted in human settlement, there is an urgent need to implement conservation measures to untangle the human-langur conflicts-for instance, reforestation of a buffer region using non-cultivated plants. There is a potential to build upon our new findings with more detailed investigations, such as more extensive ecological factors influencing the dietary adaptation which would be necessary to support conservation efforts and management decisions of this species.
带状叶猴分布于马来西亚半岛南部、柔佛州及其边境地区，包括新加坡。据估计，在马来西亚和新加坡，成熟的带状叶猴个体不足250只，该物种目前被列为极度濒危物种。关于带状叶猴甚至其他近缘物种的饮食信息鲜有报道。因此，本研究旨在描述该物种的饮食习惯，并探讨其取食行为与周围环境之间的相互作用。本研究于2018年2月至11月进行，每月有15个采样日。我们对一个由五只带状叶猴组成的焦点群体，采用间隔10分钟的扫描取样法，共收集了186个观察小时。根据带状叶猴食用的47种食物，我们识别出了29个物种，其中大部分是嫩叶（51%），其次是果实（45%）和花朵（3.8%）。研究群体花费在食用非栽培植物上的时间略多，但果实则依赖栽培植物。超过75%的果实取食涉及食用栽培植物；在大多数情况下（73%），它们只吃果肉，不吃种子。由于栽培植物种植在人类居住区，因此迫切需要采取保护措施来解决人类与叶猴之间的冲突，例如使用非栽培植物对缓冲区进行重新造林。有潜力基于我们的新发现进行更详细的调查，例如影响饮食适应性的更广泛生态因素，这对于支持该物种的保护工作和管理决策是必要的。
