Oxybelis wilsoni, a new species of vine snake from Isla de Roatán, Honduras (Serpentes: Colubridae).

A new species of Oxybelis is described from Isla de Roatán, Honduras. It differs from all species of Oxybelis in its tan to golden yellow coloration, in having a higher number of subcaudals as well as in other details of color and scutellation.

A new species of blunt-headed vine snake (Colubridae, Imantodes) from the Chocó region of Ecuador

We describe a new species of Imantodes from the Chocó region of northwestern Ecuador. The new species differs most significantly from all other congeners in lacking a loreal scale. We analyze the phylogenetic relationships among species of Imantodes based on two mitochondrial genes, and postulate that the new species and Imantodes lentiferus are sister taxa. A key to the species of Imantodes fr...

An integrative systematic revision and biogeography of Rhynchocalamus snakes (Reptilia, Colubridae) with a description of a new species from Israel

BACKGROUND The colubrid snakes of the genus Rhynchocalamus are seldom studied and knowledge of their ecology and life history is scarce. Three species of Rhynchocalamus are currently recognized, R. satunini (from Turkey eastwards to Iran), R. arabicus (Yemen and Oman), and R. melanocephalus (from the Sinai Peninsula northwards to Turkey). All are slender, secretive, mainly nocturnal and rare fo...
