Description

Excerpt: ... lineatus dunni. Although I have not seen Merten's specimens, on the basis of the excellent descriptions given by Mertens (1952b:61-62), I refer the three Salvadoranean specimens to C. lineatus dunni. The presence of paravertebral stripes in combination with the characteristics of the genus distinguish Conophis pulcher from all other snakes in southern Mexico and Central America. The only sympatric species of this genus, C. lineatus dunni, differs in that it lacks paravertebral stripes, although it may have a single vertebral stripe. Conophis lineatus dunni has lateral dark stripes that are present on the 3rd and 4th scale-rows, never on the anterior third of the body as in C. pulcher. Even in juveniles the third pair of dark stripes includes the lower part of the 9th scale-row in C. pulcher, whereas the dorsal most dark stripe of C. lineatus dunni never includes more than the lower part of the 8th scale-row.
