We describe a snub-nosed monkey that is new to science from the high altitudes of northeastern Kachin state, northeastern Myanmar, the Burmese snub-nosed monkey, Rhinopithecus strykeri sp. nov. Descriptions are based on a skin and skulls of four specimens obtained from local hunters. The new species is geographically isolated from other snub-nosed monkeys and separated from them by two major barriers--the Mekong and the Salween (Thanlwin) rivers. The species is chiefly diagnosed by its almost entirely blackish fur coloration with white fur only on ear tufts, chin beard, and perineal area, and its relatively long tail (140% of head and body length in the adult male). Preliminary surveys and interviews with hunters indicate that the new species is limited in distribution to the Maw River area, a small region of the Salween-N'mai Hka divide in northeastern Kachin state, northeastern Myanmar. The distribution area appears to cover about 270 km(2), and the species may consist of only three groups with a total population of approximately 260-330 individuals. Our data on hunting pressure suggest that the species is Critically Endangered.
我们描述了一种来自缅甸东北部克钦邦东北部高海拔地区的新型短鼻猴，即缅甸短鼻猴，Rhinopithecus strykeri sp. nov。描述基于从当地猎人那里获得的四个标本的皮肤和头骨。该新物种在地理上与其他短鼻猴隔离，与它们之间有两个主要障碍——湄公河和萨尔温江（丹伦）河。该物种主要通过其几乎完全黑色的皮毛颜色与耳簇、下巴胡须和会阴区域的白色皮毛，以及相对较长的尾巴（成年雄性中占头部和身体长度的 140%）来诊断。初步调查和对猎人的采访表明，该新物种的分布仅限于迈河地区，即缅甸东北部克钦邦东北部萨尔温江-奈梅克分水岭的一个小区域。该分布区域似乎覆盖了约 270 平方公里，该物种可能只有三个群体，总人数约为 260-330 人。我们关于狩猎压力的数据表明，该物种极危。
