Our Journey To The Yungas

Hapalotremus are a genus of tarantula spiders native to the county of Argentina, Bolivia and Peru. The elusive tarantulas usually inhabit crevices underneath rocks – sometimes without any spider silk present.

Hapalotremus martinorum is a species of green looking tarantula native to the country of Argentina which got discovered by Patricio Cavallo, Martin Gamache from Tarantula Canada and myself, Martin Hüsser from birdspidersCH. In spring 2011 we made this discovery on our last stop before returning home after a very successful but short fieldtrip to Argentinian Yungas and other regions in northern Argentina.

Revision of Hapalotremus

In 2018 the researchers around Nelson Ferreti and Rick West, namely Patricio Cavallo, Juan C. Chaparroc, Duniesky Ríos-Tamayo, Tracie A. Seimon were working on the high altitude tarantula genus Hapalotremus.

They revised the genus of Hapalotremus substantially and added seven new species to the tarantula genus Hapalotremus and were able to assert a new altitude record for the family of tarantulas (Theraphosidae).

Hapalotremus vilcanota sets the current altitude record of 4524 meters above sea level, native to the country of Peru.
