Liotyphlops beui Dixon & Kofron, 1983. Amphibia-Reptilia 4: 258. 

 Type locality: Butantan, Sao Paulo, Brazil. 



Distribution: Misiones (Giraudo, 1994) in Argentina. Also in the States of Espirito Santo, Sao Paulo, Parana 

 and Mato Grosso in Brazil and eastern Paraguay (Dixon & Kofron, 1983). Paranaense province (Giraudo, 

 1994). 



Comments: Species cited with doubts by Williams & Francini (1991). Cei (1993: 460) stated that the only 

 species of the genus that he could confirm in Argentina is Liotyphlops beui based on an adult specimen from 

 Corrientes (Departamento Capital) collected on June 5, 1990; a photograph is shown on plate 70. We believe 

 that he is refering to the specimen UNNEC 146 (same data and locality), which was examined by Dr. Cei 

 according to the person in charge of the collection (Alvarez, pers. comm.). That specimen is actually a 

 Liotyphlops ternetzii, because it has 24-22-22 dorsal scale rows and 436 dorsal scales (Giraudo, 1994). Two 

 more L. ternetzii from Corrientes city were later deposited in UNNEC. Based on this fact, we consider 

 erroneous the presence of L. beui in northwestern Corrientes. Alvarez et al. (1996), do not include this 

 species in a list of the Corrientes herpetofauna. The revised material of L. beui confirm its presence only in 

 Misiones (Giraudo, 1994). In addition, we suggest that the records from Formosa should also be revised to 

 corroborate their identity.
