Hi fellow collectors! I collected these this summer in Switserland (3 km south-east of santa maria val müstair on 2050 m approx.) I have ID them and think they are Erebia tyndarus. They as well look like E. nivalis but they don't fly there.. Am I right with tyndarus? What are the characteristics I have to watch for..? Thank you in advance! Attachments:

It is Erebia tyndarus unless I did use my book wrong... I am talking here about the best book in the world: "Die Erebien der Schweiz - Peter Sonderegger". This guy is the godfather of Erebia and the book is the best lepidoptera book ever written. Erebia cassioides and Erebia nivalis can be confused with tyndarus, but the distribution in Switzerland has pretty clear regions unless 9 places where cassioides and tyndarus meet and each place has a chapter on it's own in that godlike book! ( E. nivalis is out of the game anyway because it is only at one mountain in the middle of Switzerland  ). Furthermore Erebia nivalis likes to fly 2300m upwards, another hint for E. tyndarus |

I did read the chapter on that species group now trough and it actually is a very interesting species group. Erebia cassioides and nivalis have disjunct areals and there was the possibility of Erebia cassioides to get to the place you where via Italy, I did try to redraw the map of the book. Anyway Erebia tyndarus and Erebia cassioides can be determined by outside looks ( of course genitalia is better) but Erebia tyndarus has a more round apex and kind of small eyespots, they may be missing and they are disjunct...in Erebia cassioides the apex is somewhat sharper and the eyespots are always large, often cojoint. Your specimen clearly have small spots and the second one even is missing the white. Thank you for posting this because I had Erebia sp. from Calanda Mountain this year and I did not have the interest yet to check what species it is Now I know I got E. tyndarus too. I hope you didn't get only two of them as the species can be a pest high up in the mountains, a friend once had sitting 4 of them on him sipping sweat and I caught like 20 of them:) For those that can't speak German: Schweiz=Switzerland Österreich=Austria Attachments:

Hi!
Yes, it is a nice group with an interesting areal splitting!
Thanks again!
