|Diagnosis||Diagnosis. A Pseudoboa that differs from all other species of the genus by the retention of a large pale collar in large individuals, and by the absence of apical pits on dorsal scales. Further differs from Pseudoboa haasi, P. nigra, and P. neuwiedii in having 17 instead of 19 dorsal scale rows, and from P. nigra and P. neuwiedii in the presence of seven instead of eight supralabial scales.|
|Comment||The new species is distinguished from the other five species of the genus by a combination of scalation and coloration characters. Individuals of the new species were found in both primary and disturbed forested areas. The species seems to be predominantly nocturnal and secretive because specimens were found foraging in the litter during night.|
ZAHER et al. (2008) nicely illustrate the ontogenetic shift of color patterns in this species.
|Etymology||The specific name, a noun in the genitive case, honors Dr. Marcio Martins for his invaluable contri- bution to knowledge of the natural history of Brazilian snakes. Dr. Martins studied the biology of Amazonian snakes during his years as a Research Associate of the Universidade Federal do Amazonas, Manaus (UFAM).|
