There is a number of similar specimens from very high mountains (some even up to 5000 m above the sea, found on ice) of Argentinian and Chilean Andes. These earwigs seems to be resistant to low temperatures as many has been found on ice or rocks at very high altitude (some even up to 4300 m above the sea).

Species 1?

Comment about size from Holger Braun (orthopterologist from Museo de la Plata who observed them):
"I hardly remember, more or less like Forficula auricularia, perhaps slightly bigger. It's not easy to get there."

I think it may be undescribed Anisolabididae (Brachylabidinae or Gonolabidinae?) or Pygidicranidae (Esphalmeninae?) species or two species.
Provisionally I have identified them as Brachylabidinae on iNat.

There is a number of species of Esphalmenus species known from this area of the Andes (E. lativentris known from many places in Argentina and Chile, E. basidentatus, E. bidentatus in Argentina, E. kuscheli, E. weidneri, E. porteri in Chile) but these specimens do not fit any knowns species of the genus.

I found only one adult Esphalmenus on iNat for high altitude in Argentian Andes, identified by me as Esphalmenus weidneri (best fit by key, but may be another spacies as well):
https://www.inaturalist.org/observations/141644049
https://www.inaturalist.org/observations/206273770 (same specimen)
Reported to be observed at 4500 m (Camila Zambruno: "Es en la cordillera de Ansilta (san juan) subiendo al pico 3 de Ansilta a más o menos 4500 msnm")

No native Anisolabididae except of Brachylabis chilensis (small reddish brown species and with curved forceps) and Gonolabina spectabilis (quite big and characteristic species from litoral of Chile) known and these specimens don't fit its description.

Actually there is mention that Gonolabina is probably related to Esphalmenus more than to Anisolabididae which was suggested by one specialist in Dermaptera from Argentina - Roxana Mariani, and in one article that I have, it is mentioned that Gonolabina is Pygidicranidae. This has been followed in article by Chilean entomologist Alejandro Vera.

I have a guess that may be these 1or 2 undescribed species are related to Esphalmenus and Gonolabina and also belong to Pygidicranidae.

Also Roxana Mariani presented in one conference 5 new species of Esphalmenus genus (Pygidicranidae) but these never got published and currenty not listed at DSF (I will add them as names without description to DSF later), mentioned only in the conference paper without any description (I have this paper, but there are only names and mention that all were found along Cordillera de los Andes in Argentina and museum collections used in the work (for all without more data):

She also did a thesis on Esphalmeninae which I do not have:
