Taxonomic Etymology:
A slender, arboreal snake with characteristically small eyes.
Oxybelis — From Greek oxys (ὀξύς), “sharp” or “pointed,” and belos (βέλος), “dart” or “missile.” The name refers to the snake’s elongated, pointed head and slender, dart-like body.
microphthalmus — From Greek mikros (μικρός), “small,” and ophthalmos (ὀφθαλμός), “eye.” The name means “small-eyed,” referring to the species’ relatively small ocular size compared to other Oxybelis.
