Not listed as such by WELCH 1994 or mentioned by FENWICK et al. ![]() Synonymy: Synonymy partly after PETERS & OREJAS-MIRANDA 1970. Table 2 summarizes distinguishing characteristics of these similar species (Harvey 2005: 16). In the other species, the dorsal surface of the tail is about the same color as the dorsal blotches and does not sharply contrast with the dorsal pattern. The tip of the tail darkens with age, but it is most distinct in adult Bothrops sanctaecrucis where the distal tail is black dorsally and ventrally sharply contrasting with the base of the tail. In neonates and juveniles of these four species, the caudal oneto two-thirds of the tail is yellow. moojeni have curving stripes on their necks. sanctaecrucis has a pale green iris (pinkish copper to bronze in the other species) and Bolivian B. ![]() sanctaecrucis) keeled scales between the canthals (vs. sanctaecrucis may further be distinguished from B. The venter of Bothrops brazili is also moderately to heavily pigmented, but the other two species have cream venters with only a very diffuse pattern not consisting of staggered squares. atrox is rather heavily pigmented and consists of staggered cream and gray to black (=melanophores) squares (lowland populations) or is uniformly and heavily speckled (specimens from the Andean slopes in La Paz). When present, the postocular stripes of the other species are one scale high (vs. atrox have well-defined, high, dark brown postocular stripes. Although not yet collected in Bolivia, B. Bothrops sanctaecrucis occurs in sympatry with B. sanctaecrucis are rather easily confused with one another (Table 2). ![]() Atrox terrestrials rar series#atrox is distinguished from all congeners and from species of Bothrocophias and Bothriopsis by the following combination of characters: (1) lacunolabial present (2) dorsal keels nontuberculate (3) infralabials and gulars pigmented to varying degrees but lacking regular series of cream round to C-shaped marks (4) canthorostrals absent (5) subcaudals divided (6) ventrals 182–200 and subcaudals 54–72 (7) loreal subtriangular, higher than long (8) canthals narrow and separated by 3–7 scales (9) internasals usually in contact, separated by one scale in 22% of the sample (10) postocular stripe distinct and brown two temporals high (11) dorsum brown, pattern of subtriangular blotches or French telephone-shaped marks venter uniformly and heavily speckled (populations on Andean slopes) or with alternating cream and charcoal, square blotches (Harvey 2005: 16).Ĭomparisons among B.
