A new species of Geophis of the sieboldi group (Reptilia : Squamata : Colubridae) from northern Honduras

A new species of Geophis from northern Honduras is described. It is a member of the sieboldi group, the largest and most geographically extensive of the seven species groups currently recognized in the genus. With the inclusion of this species, the sieboldi group now contains 15 species, which range from Michoacan, Mexico, to Colombia. The new species can be distinguished from the other members of the sieboldi group by the combined presence of 15 rows of smooth scales throughout the body, six supralabials, one supraocular, one postocular, dark gray dorsum with reddish-orange markings, and a white venter with a gray band on the anterior edge of each scale. The new species seems to be most closely related to G. brachycephalus.
