This was a first for me in 2005. I believe that these are all rondoui which until recently was regarded as a form of the Spanish Brassy Ringlet (E. hispania). Tristan Lafranchis, in his latest book on identifying European species, divided hispania into two distinct species, hispania occurring in the Sierra Nevada in southern Spain, and rondoui now being described as the "Pyrénées Brassy Ringlet" confined to the Pyrénées, and I have followed this classification. 

The females on this page were seen in 2005 just on the Spanish side of the Pyrénées, at 2070m. However, on a return visit to this location in 2015, the whole area had been grazed to extinction and almost no butterflies were seen.

It is quite easy to identify as the upf twin ocelli differentiate it from all other smallish Erebia in that locality. The twin upf ocelli are fused, although not as closely fused in these photographs as in the illustrations in T&L.

observations

alt. m
38801 M a male, based on its behaviour and what can be seen of the body shape, although the upf red post-discal band surrounding the ocelli is rather broad and extends down almost to s1, perhaps suggesting female. 2070
38832 M a very dark male, as body shape almost certainly confirms, with a very restricted upf red post-discal band. The ocelli are very bright, especially on the uph, which would tend to suggest female. 2070
05_25-05 F

a female, from the body size and because the upf post-discal band extends into the discal area.

2070
38809 M a male underside, with a very vestigial unh discal line and generally almost unmarked. 2070
05_26-34 F

a female, the underside being slightly browner and having a clear discal line, at least in the upper part of the unh.
