Philodryas olfersii latirostris Thomas, 1977. Diss. Abst. Int. 37 (8): 167. 

 Type locality: Brazil 



Distribution: Misiones, northern and eastern Corrientes, and eastern Entre Ri'os (through Uruguay River). 

 Also from Minas Gerais, Brazil, to Uruguay (Giraudo, 1997). Paranaense province. 



Comments: Thomas (1977) and other authors (Gallardo, 1986; Williams & Francini, 1991; Cei, 1993) 

 mentioned P. o. latirostris throughout Argentina, including Misiones. Giraudo (1997) studied the species in 

 Argentina and bordering areas of Paraguay and concluded that the populations represented P. o. olfersii. This 

 subspecies is characterized by having the dorsum of the head golden brown followed by a vertebral line of 

 the same color. This color is remarkably different from the green color on the rest of the body. It also has a 

 postocular line broader than the one in P. o. latirostris and shows statistically significant differences in 

 number of ventral scales, subcaudal scales and caudal length/ total length ratio.
