15 20/ problemas relacionados, André de Masao Machado Herculani, Tomo III (1953) pág 105-124, after a strong pitch for relating Australasia and Patagonia acts via Bering Straits rather than Antarctica, he says Campsotoma punctatus ad Acromyrmex lobicornis have extraordinary adaptability and considerable versatility. C.P. very common from N. Argentina to Chubut (Catar del, Zapata) and "a form of this species is common in the humid regions of Tucuman. It on the altitudes of the NW the species lives above 4000m, "For this reason it is strange that this species has not yet penetrated into humid Patagonia." p123 Similarly in A.L., with the difference that it has few local forms, it is found close to humid Patagonia (Catar del), without penetrating even to the Valle Aluminé, an unidentified form is in missions with 200mm of rain. It has lost part of its "afinidad hereditaria" in crossing the arid zone of the interior of Argentina and is waiting for evolution to equip it to enter the humid zone. He doesn't list Acromyrmex for the Parques (N.H. y Zaving y) Horvits and I saw a very large actus and heap yesterday off the canyon, they were carrying dry stems, leaves, etc. not green, and piled them in a 10-gallon bags. It seems that this morning the fog (cloud) layer formed + reformed many times at a level where there were many cypress. Perhaps they are dependent on summer fogs?
