Atractus dunni is a highly variable species in terms of its coloration, having ontogenic and intraspecific variation. However, the differences between A. lehmanni Boettger, 1898 and A. dunni are subtle.
Diagnosis: A species closely related to Atractus gaigeae, but distinguished from that form and other Ecuadorian Atractus as follows: (1) 17 scale rows; (2) long loreal; (3) maxillary teeth not known, probably less than nine; (4) ventrals in female holotype, 144, probably about 10 fewer in males; and (5) pattern of five longitudinal dark stripes and two series of spots [from SAVAGE 1960].
|Etymology||Named after Emmett Reid Dunn (1894-1956) [obituary in Schmidt 1957: 75].|
