>Bonjour,
Ici sur un staphylin (Philonthus politus), en particulier sur le pronotum
- forme sphérique à ovoïde
- petite taille
- possède un appendice de fixation (cf cliché)
un Scutacaridae ?

Ce sont des deutonymphes d'Uropodoidea avec cet appendice anal !
Il y a eu un cheminement pour en identifier ici, mais ce n'est pas évident et je n'ai pas la doc. Je vais demander de l'aide.
Voici la réponse de Matthew Shepherd :
"The arrangement of families in the Uropodoidea is a horrible mess. I've found it's easier to identify the creature to species, then assign it to whatever family seems to be popular at the time! I've been putting together a rough key based on whatever descriptions i can find for the UK Uropodoid fauna, if you're interested to borrow it? It may not work well for France... In 1998 Cillba was a subgenus of Uropoda, but recent authors have it as the basis for its own family! For a while the Dinychidae contained a lot of the Uropodoid mites such as Oodinychus, Pseudouropoda and Uroobovella, but these are now, i think in the Trematuridae (first 2), and the Urodinychidae (last one). I'm not sure Pseudouropoda is a real genus, anyway. It seems to be a dumping ground for species that haven't been properly described! Also, there is likely to be high levels of endemism among the Uropodoidea, which means that there may be lots of valid, poorly described, locally distributed species. We need a big, pan european genetic study, to try to sort all this out"
Bref, c'est un peu le souk dans cette super famille, le nombre de familles et de genre n'est pas clair et leur classification non plus
