One of the aberration descriptions refers to the attached figure. Goodson and Read (who created the listing used on UKB) have this down as Pearl-bordered Fritillary, even though the original author has it down as Small Pearl-bordered Fritillary.

Any thoughts, other than it's difficult to discern given the illustration!

I don't know if this will muddy or clear the waters, but rinaldus is given as an aberration of selene here:



Taken from Supplément à la Faune des Macrolépidoptères du Valais, which can be searched as a pdf online.

Thanks Guy! Are you able to provide a link since I can't seem to find this online.

The original definition referred to be Goodson and Read is here, from 1800 and it looks like your definition is referring to that (and the plate): https://www.biodiversitylibrary.org/ite ... 2/mode/1up

Here's what Goodson and Read wrote (as you'll see, I've been tinkering with a few things offline!):

Hi Pete. It's not easy to navigate, but the complete book, with the supplement, is online, and the relevant page is here:

Bozano gives rinaldus as a synonym of selene but doesn't discuss it.

I'm sure you have South, so you will have confirmed there is a similar underside there of euphrosyne, without an upperside. However, the upperside of a very similar euphrosyne in Howarth is quite different and Howarth also shows a very similar selene underside, with its upperside (closer, but not at all the same). Howarth calls that individual vanescens.

To me, the original plate you showed looks more like selene, but with such extreme aberrations I have no confidence in my diagnosis!

I'll keep looking!

Thanks Guy - all very helpful!
