Morphological comparisons reveal considerable affinities between Bothrops ammodytoides , Bothrops pictus , Bothrops

Lepidosis and hemipenial characters have been investigated and tabulated to give an impression of the intraspecific variation. The data of the new specimens provide some information on the natural

The lepidosis is very similarto the one of the types (given in parenthesis), having 19 scale rows at midbody, 145 ventrals (149), divided anal, and 2/2 + 3 + 64/64 subcaudals (63 - 67). It differs from the types
