TORQUATUS '« GROUP 



Species. — Twenty-one forms, representing 10 species, are recognized. 

 Range. — Arizona and Texas south to Guatemala. 



'• This group was in 1938 termed the poinsetlii group, inasmuch as Sceloporus poinsettii Baird and Qirard 

 (1854) was the oldest name in the group after exclusion of S. torqiiatus Wiegmann, 1828. The latter name 

 was considered unavailable because it was once (Wagler, 1830) placed in the genus Tropidurus, in 

 which the combination Tropidurus torguatus (Wied, 1820) had already been made (Wied, 1824). Secondary 

 homonyms, such as this, have not, however, been regarded in recent years as permanently suppressed: 

 they are suppressed only as long as they actually remain homonyms. Accordingly, we revert to the 

 name torquatut for this group.
