Hm one more question: in Fauna Europaea the species name is "Eriothrix rufomaculatus". What is right the male or the female form?

Herting in his catalogue of 1984 used the spelling "Eriothrix rufomaculata". Dely-Draskovits (1993) changed the gender of Eriothrix to masculine, and Tschorsnig followed this spelling for the Fauna Europaea. But I heared from Ziegler that Tschorsnig has now accepted the feminine gender of Eriothrix.

'Thrix' is the classic Greek for 'hair' and its gender is female.
So classic Greek grammar compels to right ending '-a'.
But no doubt Dely-Draskovits used some (in my opinion) weird article of the Code to decide otherwise....
Be my guest to write '-us', but it is bad Classics !

By the way, rule of thumb
Nouns with ending in '-o', '-s', or '-x' are feminine
There are exceptions !!!
(that is why it is a rule of thumb)

My videos are created for use in the different language editions of wikipedia. Media files are stored on commons centrally. So I searched the English wikipedia and found an article titled "Eriothrix rufomaculata". On commons however the species category is called "Eriothrix rufomaculatus". Now in my file description I will use the species name ''E. rufomaculata'' (following your opinion) and the file is categorized as "E. rufomaculatus" (following FaunaEuropaea).
Looking to FaunaEuropaea the confusion is going on:
The genus contents
Eriothrix accolus Kolomiets, 1967
Eriothrix apenninus (Rondani, 1862)
Eriothrix argyreatus (Meigen, 1824)
Eriothrix inflatus Kolomiets, 1967
Eriothrix micronyx Stein, 1924
Eriothrix monticola (Egger, 1856)
Eriothrix prolixa (Meigen, 1824)
Eriothrix rohdendorfi Kolomiets, 1967
Eriothrix rufomaculatus (De Geer, 1776)
Sometimes male sometimes female, for me it looks very strange....
Hoping somebody will solve the problem on FaunaEuropaea in the future, with best regards Ingo
