Type species: Typhlops nigricans Schlegel. 



Comments: the genus is under revision in Argentina, and the preliminary results indicate that there are 

 synonyms among the species mentioned in the country and that the distribution is different from that 

 commonly accepted until now (S. Kretzschmar, com. pers.). Until the revision is completed, we note the 

 species as they are accepted today, except for L. albifrons, as was stated in the introduction.
