Systematic references — McDiarmid and Folke (1991); McDiarmid (1992). 



Remarks. — This species was regarded as monotypic by McDiarmid (1992), who 

 synonymized Tantilla deviatrix Barbour, 1916, given subspecific status within T. bocourti by 

 Smith and Laufe (1945), with T. wilcoxi Stejneger, 1902. 



McDiarmid and Folke (1991) noted that two specimens were originally included under the 

 number MNHNP 3694, and that one of them was sent to another museum (probably the 

 British Museum of Natural History) in 1894. They concluded that such did occur and that the 

 sent specimen is now BMNH 1946.1.8.70. They noted that iectotype designation was 

 accomplished by Boulenger (1896a), and that as a consequence, the specimen MNHNP 3694 

 currently in the Paris Museum is the paralectotype of T. bocourti.
