Which Yarara species possesses a wider distribution across the central and northeastern Argentinian provinces?

Answer

*Bothrops alternatus*

*Bothrops alternatus*, also known as Urutu or Yarará Grande, demonstrates a considerably broader geographical spread within Argentina compared to *Bothrops jararaca*. *B. alternatus* is confirmed across a vast array of its central and northeastern provinces, totaling thirteen listed locations, extending from low-lying areas up into rocky highlands like the Sierras. Conversely, the range cited for *B. jararaca* is much more restricted, focusing mainly on the Misiones province, suggesting *B. alternatus* has superior adaptability across diverse topographies and ecological zones within the country.
