Porthidium lansbergii is a venomous pitviper species found in Central and South America. Currently, four subspecies are recognized, including the nominate subspecies described here.[3]

Geographic range

Found in extreme eastern Central America in the xeric coastal lowlands of central and eastern Panama. In northern South America in the Atlantic lowlands of Colombia and northern Venezuela, as well as the Pacific lowlands of Ecuador. The type locality given is "les environs de Turbaco [Department de Bolívar], en Colombie" According to Amaral (1929), likely from Tumaco.[1]

According to the range map provided by Campbell & Lamar (2004), the subspecies P. l. rozei and P. l. lansbergii intergrade in the northern part of the Guajira Peninsula.[2]
