Argentina – A new species from Salta! Hapalotremus martinorum sp. nov.

Argentina – A new species from Salta! Hapalotremus martinorum sp. nov.

In April 2011, Pato Cavallo, Martin Gamache and myself, Martin Hüsser, made a short trip through the north of Argentina. During this trip we were able to find a new species which now is described and got finally a name. Hapalotremus martinorum sp. nov. (Cavallo et al. 2014) is the name of this beautiful terrestrial species which reminds in it’s appereance a bit of a species from the Cyriocosmus sellatus – complex.

After a few days in the Yungas and then a few days searching for Grammostola high up in the mountains we decided to set camp for one last time before returning to Buenos Aires. Later the day, as the tents were ready we went to a short walk near our camp to search for Theraphosidae. After some minutes of searching in the thorny forest, We were lucky enough to find a small specimen of a tarantula with a greenish hue. We all got very excited as we thought this had to be Cyriocosmus versicolor. Fully motivated we searched the whole area, turned every singel rock and rotten log. It was definately worth the effort as Martin and I found another specimen which was a lot bigger but still hat similarities to the small one. In total we found three specimens this day, one big adult female and two small juvenile specimens. Because we were not in a National Park, we had the permission to take the specimens back to Pato’s place in Buenos Aires, the spiders did not have to leave the country for it’s further investigation.

After a few months one of the small juvenile specimens matured, it was an adult male. Finally Pato could work on it’s description as we now had a specimen of each sex. Here you can find the link to the published paper of Hapalotremus martinorum sp. nov. (Cavallo et al. 2014).
