摘要：
Shaw's black-backed snake, Liophis melanotus, occurs in northern Colombia and Venezuela, Trinidad, and Tobago. Geographic variation of morphological characters and the color pattern of this colubrid species is assessed. A total of 198 individuals were examined. No sexual dimorphism was found in any character using Student t tests. Variation within 24 character states was significant between the Colombian, Venezuelan, and Trinidad-Tobago samples. Two new subspecies (L. m. lamari and L m. nesos) are described, based upon a multivariate analysis of the 24 character states and color pattern.
