}} Common names: black-headed bushmaster.[2]Lachesis melanocephala is a venomous pit viper species found in Costa Rica. No subspecies are currently recognized.[3][4] DescriptionAdults frequently grow to {{convert|1.9|–|2|m|ft|abbr=on}} in total length. The largest reported specimens were {{convert|2.3|m|ft|abbr=on}} by Solórzano (2004), and {{convert|2.4|m|ft|abbr=on}} by Ripa (2001). The top of the head is uniform black in color,[2] to which the specific name, melanocephala, refers. Geographic rangeFound in Costa Rica on the Pacific versant of southeastern Puntarenas province from near sea level to about 1500 m (about 4,900 feet). The type locality given is "tropical rainforest 9 km northern of Ciudad Neily in southeastern Provincia de Puntarenas, Costa Rica."[1] 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.[2] See also
