Now is finished the study of the prey caught by an exotic Crabronidae wasp specialised in jumping spilders (prey caught on July 2021 in Spain: Catalonia: Girona province: Girona city):

10    14,5 Evarcha jucunda
32    46,4 Heliophanus apiatus
 4     5,8  Heliophanus kochii
 4     5,8  Heliophanus tribulosus
17    24,6 Icius hamatus
 2     2,9  Salticus mutabilis
69   100   

[There were also 35 undetermined Salticidae]

Between them it seemed to be a female "H.tribulosus" looking at opisthosoma pattern, ...

... but looking at the epigyne it was a clear Heliophanus apiatus :o !

For me also based on the opisthosoma pattern ;-)

Thanks Michael ! I used to think that some tribulosus (and typical rufithorax, see https://araignee-sauteuse.fr/index/france/heliophanus/rufithorax) could be recognized by the white spots on opisthosoma surrounded by black. Could you tell me how could you recognize a cear female apiatus ?

I can't tell you like that. That is simply experience. I have seen several such apiatus females in the past. Look for example on my web page at the bottom the female from Sardinia:

Females of rufithorax as I know them look quite different:

I didn't say that I had 100% determined the species from the photo, but that it looks like H. apiatus to me ;-)

However, with this genus, I would never determine specimens based only on their appearance - especially in the Mediterranean region.

Whether the spiders from your link actually show "TYPICAL" rufithorax females is doubtful in my opinion. As very often in the Internet with specimens determined on the basis of photos.

And even when determined by genitalia, these species are very difficult to classify because the genitalia are very similar and also very variable. It is best to have males at hand at the same time.

Kind regards
Michael
