Panama – Up in the mountains

Panama – Up in the mountains

We spent a couple of days in the mountainous area up to 1650 meters above sea level, just on our way to the Caribbean side of Panama. The climate in this high altitude was pretty different, much colder but a lot wetter than the pacific coast. We stayed for a few days in a nicely build and remote Hostel in this forest area, the up steep was pretty difficult with all the luggage but definitely worth it. The vegetation was so pretty, dense and just green – a really nice piece of primary rainforest here in Panama.

During the day and night we spent time walking on all the paths up and down on this hilly rainforest and searched for tarantulas. We managed to find two specimens of a (or two?) Sericopelma species, one adult female and a nymph, probably third molt.

Psalmopoeus sp. Panama

Sericopelma sp. Lost&Found - Panama

The special thing about this find was, that the spiderling had white markings on tarsus and metatarsus on all his legs, this is something we have never seen before on specimen in this genus. We know about this kind of “color feature” in the genus Theraphosa. The species T.blondi has white markings only on tarsus, while T.apophysis got it on tarsus and metatarsus. So this might be some kind of distinguishing feature for young specimens of this genus aswell. The time will tell.

Another find the staff of the Hostel made, was an adult female of a Psalmopoeus species of which we believe it’s a new species but closely related to P.reduncus. The habitat, altitude and distribution of this Psalmopoeus species is really different to P.reduncus, which we found later on at the Caribbean side of Panama.
