May 14, 2013 — A new species of green palm-pitviper of the genus Bothriechis is described from a seriously threatened cloud forest reserve in northern Honduras. Because of similarity in color pattern and scalation, the new species (Bothriechis guifarroi) was previously confused with other Honduran palm pitvipers. Genetic analysis revealed that the closest relatives of the new species are actually found over 600 km to the south, in the mountains of Costa Rica.

The study was published in the open access journal Zookeys.
The gorgeous new species was discovered by scientists during two expeditions in 2010 aimed at studying the fauna of Texiguat Wildlife Refuge, one of the most endemism-rich and diverse highland forests in Mesoamerica. This beautiful, but highly toxic, snake represents the 15th endemic species occurring in the region. Texiguat Wildlife Refuge was created in 1987 to protect populations of wildlife such as the famous but elusive jaguar and Central America tapir, as well as howler and white-faced monkeys, sloths, and a variety of endemic amphibians, reptiles, and plants.
To draw attention to the dedication and sacrifice of many grassroots conservationists in Honduras and Central America, the new species was named in honor of Mario Guifarro of Olancho. Guifarro was a former hunter and gold miner who became an outspoken conservationist when he saw the vast rainforests of eastern Honduras being destroyed and converted to cattle ranches. After years of threats and multiple attempts on his life, Guifarro was ambushed and murdered on 15 September 2007 while on a mission to delimit a biosphere reserve for the indigenous Tawahka.
