Philodryas aestivus subcarinatus Boulenger 1902 



Philodryas subcarinatus Boulenger, 1902. Ann. Mag. Nat. Hist. (7) 9:287. 



Philodryas aestivus subcarinatus Barrio, Laurent & Thomas, 1977. J. Herpet. 1 1 (2): 230. 

 Type locality: Colonia Benitez, Itapua Department, Paraguay. 



Distribution: Buenos Aires, Cordoba, Corrientes, Chaco, Entre Ri'os, Formosa, Misiones, Salta, Santa Fe, 

 Santiago del Estero, and Tucuman (Barrio et al., 1997; Corbella, 1989; Couturier & Grisoh'a, 1989; Williams 

 & Wichmann, 1989; Giraudo & Quaini, 1997). Also in Rio Grande do Sul, Brazil, Paraguay and Uruguay 

 (Thomas, 1977; Giraudo, 1997; Achaval & Olmos, 1997). Pampeana, Espinal and Chaquena provinces and 

 bordering areas of Paranaense province (Campos district). 



Comments: Philodryas aestivus aestivus and Philodryas aestivus subcarinatus are distinguished by 19 and 

 21 rows of scales at midbody, respectively. D'Agostini (1998) stated that the geographic distribution of the 

 character is irregular and declared the subspecies as invalid. We disagree with D'Agostini, because in her 

 Figure 1 the majority of specimens from Argentina, Paraguay, Bolivia and Rio Grande do Sul (Brazil) have 

 21 rows (except 2 specimens from Argentina with 19), whereas the majority of specimens from Parana, Sao 

 Paulo, Rio de Janeiro, Minas Gerais, Mato Grosso do Sul and Brazilia have 19 rows. Also, Philodryas 

 aestivus aestivus inhabits humid forests and jungles and is semi-arboreal; whereas, in Argentina, P. a. 

 subcarinatus inhabits grasslands and open areas (Giraudo, 1997). 



Philodryas aestivus ssp. 



Distribution: Salta and Jujuy. In Bolivia only known from type locality (see comments). Yungas Province. 

 Comments: This population from Bolivia was recognized as distinct by Thomas (1977), yet a description 

 has not been published. The present inclusion in the Argentina fauna is based on eight specimens housed at 

 Fundacion Miguel Lillo.
