We describe a new species of montane pitviper of the genus Bothrops from the Cordillera Oriental of the CentralAndes, distributed from southern Peru to central Bolivia. The new species can be distinguished from its congenersby the characteristic combination of a dorsal body color pattern consisting of triangular or subtriangular dark browndorsal blotches, paired dark brown parallel occipital stripes, a conspicuous dark brown postocular stripe, the presence ofcanthorostrals in some specimens, prelacunal fused or partially fused with second supralabial, one scale usually separatinginternasals, rostral trapezoidal, two canthals oval to rounded, similar size or slightly larger than internasals, three or fourmedial intercanthals, eight to twelve intersupraoculars, intercanthals and intersupraoculars keeled and frequently slightlykeeled, supraoculars oval, one to three suboculars, two to three postoculars, loreal subtriangular, two to six prefoveals,subfoveals absent, two or none postfoveals, one or two scales between suboculars and fourth supralabial, seven or eightsupralabials, nine or eleven infralabials, 23?25 middorsal scales, 189?195 ventrals in females and 182?190 in males,48?58 subcaudals in females and 54?63 in males, exceptionally undivided. The new species is apparently restricted toareas within Andean montane forests that are less humid and devoid of large trees.
