Helicops petersi Rossman, 1976

Diagnosis

Helicops petersi can be distinguished from all its congeners, except H. yacu by the combination of present intergenials, absent subcaudal keels and 135-150 ventrals (versus 110-125 in H. scalaris ; 114-130 in H. trivittatus ). From H. yacu , it differs in having a semi-divided nasal scale (versus entire in H. yacu ); (for information on references, see Suppl. material 3).

Distribution

Helicops petersi is known only from a very small area in the Ecuadorian Province Napo (Fig. 3 a).
