Leptophis ahaetulla is bright green, arboreal coulubrid snake found in South America and Trinidad and Tobago. It has been regarded as a suspiciously variable species, which indicates it may be a cryptic species complex. In this study, we compare 11 specimens of Leptophis ahaetulla using DNA sequences from the mitochondrial genes 16S and cytochrome b (1,383 bp total). The phylogenetic analysis reveals a strongly supported clade comprised of the island specimens, indicating they are a separate species from L. ahaetulla. Thus, Leptophis coeruleodorsus (Oliver, 1942), formerly a subspecies of L. ahaetulla can be given full species status.
