Common names: Lansberg's hognosed pitviper.[2]

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]


The specific name, lansbergii, is in honor of "M[onsieur]. de Lansberge" (Reinhart Frans von Lansberge), Dutch consul at Caracas, Venezuela, in 1841.[4]


Adults average 30–50 cm (11 3419 58 in) in total length with a maximum of 90 cm (35 12 in). Terrestrial and moderately slender.[2]

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]
