Lachesis melanocephala is a species of venomous pit viper in the family Viperidae. The species is native to Costa Rica and Panama. There are no subspecies that are recognized as being valid.[3][4]

Common names

[edit]

Common names for L. melanocephala include black-headed bushmaster,[5] as well as cascabel muda ("silent rattlesnake") and matabuey in Spanish.

Description

[edit]

Adults of L. melanocephala frequently grow to 1.9–2 m (6.2–6.6 ft) in total length (including tail). The largest reported specimens were 2.3 m (7.5 ft) by Solórzano (2004), and 2.4 m (7.9 ft) by Ripa (2001).

The top of the head is uniform black in color,[5] to which the specific name, melanocephala, and common name refer.

Geographic range

[edit]

L. melanocephala is found in Costa Rica on the Pacific versant of southeastern Puntarenas province from near sea level to about 1500 m (about 4,900 feet). It is also found in Finca Hartmann in Panama's Chiriqui Province. The type locality given is "tropical rainforest 9 km northern of Ciudad Neily in southeastern Provincia de Puntarenas, Costa Rica."[2]

Campbell and Lamar (2004) describe its range as southwestern Costa Rica and possibly extreme western Panama, but state that almost all locality records are from Puntarenas province.[5][6] Savage (2002) and Dwyer & Perez (2009) confirmed its existence in Panama.[1]

Diet

[edit]

L. melanocephala preys predominately upon small rodents, especially spiny rats.[1]

Reproduction

[edit]

L. melanocephala is oviparous.[3]
