Distribution: Catamarca, Cordoba, La Pampa, La Rioja, Mendoza, Rio Negro, San Juan, San Luis, Santiago 

 del Estero and Tucuman (Tiranti & Avila, 1997; Avila & Morando, 1999). Chaquena, Monte and Espinal 

 provinces and transitional areas between Espinal and Pampeana (Pampeano Austral district) provinces.

Type locality: Estancia Postilion, Puerto Max in Paraguay River, Paraguay. 



Distribution: Chaco, Formosa, Jujuy, Salta and Santa Fe (Giraudo & Quaini, 1997). Chaquena province. 

 Comments: Rey & Lions (1996) mentioned a specimen in Corrientes, Capital. However, it was captured in 

 the neighborhoods of a laboratory for the production of antivenom serum which maintain snakes from 

 diverse origins in captivity (L. Rey pers. com.). All the specimens from Corrientes, including various of 

 Capital Department are O. r. rhombifer (Giraudo, 1997). It is possible that the record of Rey & Lions is 

 based on an escaped specimen and for this reason, we do not include O. r. inaequifasciatus in Corrientes.

Elapomorphus {Phalotris) Lema, 1984. Iheringia (zool.) (64): 61. 

 Type species: Elapomorphus tricolor Dumeril, Bibron & Dumeril, 1854, Erp. Gen., 7: 837. 

 Comments: The genus, used as subgenus by some authors (Lema, 1984; Cei, 1993, inter alia), was 

 revalidated by Ferrarezzi (1993, 1993a) for the species formerly included in Elapomorphus with a single 

 prefrontal scale. Therefore, all Argentinian species are Phalotris. The genus Elapomorphus is restricted to 

 three species that have two prefrontals scales. 



Also, Ferrarezzi (1993) and Puerto & Ferrarezzi (1993) reorganized the taxonomy of the genus based on 

 priority of the names, and they did not recognize races or subspecies as other authors had (Lema, 1994 

 considers several in P. bilineatus (= Elapomorphus spegazzinii), and P. lemniscatus). We use the approaches 

 of Puorto & Ferrarezzi, because several specimens of P. bilineatus cannot be assigned to a subspecies based 

 on Lema (1994), and because the majority of the taxa are known from a few specimens and their geographic 

 variation is not well know. 



Although six species have been reported from Argentina, during the examination of all specimens in 

 Argentinian Museums, no specimens of Phalotris tricolor were found. All specimens identified as this 

 species were actually Phalotris punctatus, a very similar species (Giraudo, 1997).
