Sorry, but I don't have enough knowledge
Nor have I ever seen what they call "benacensis", so I can say little ...
Salut
Ok for the synonymy
It’s gonna be a little confusing to call aurelia benacendis but it’s the good taxonomic way let’s do it …
Aurelia is not prioritary because it’s considered as specie and not subsp ? That’s correct ?
No, I just made a small mistake, because benacensis is the priority name (older) both at subspecies and species level :
Ophrys bertoloniiformis subsp. benacensis Reisigl, Orchidee (Hamburg) 23: 163 (1972).
Ophrys benacensis (Reisigl) O.Danesch & E.Danesch, Pl. Syst. Evol. 124: 108 (1975).
Ophrys bertolonii subsp. benacensis (Reisigl) P.Delforge, Bull. Soc. Roy. Bot. Belgique 115: 276 (1982).
vs
Ophrys aurelia P.Delforge, Devillers-Tersch. & Devillers, Naturalistes Belges 70: 77 (1989).
Ophrys bertolonii subsp. aurelia (P.Delforge, Devillers-Tersch. & Devillers) Kreutz, Kompend. Eur. Orchid.: 87 (2004).
Ok
I'm just discovering the subspecies in the complex. I used to stick to the bertolonii species, so no matter for me. both seem fine.
OK, I will validate the change. Thanks to all. Don't hesitate to comment more if needed...
A different view is that O. benacensis from the North of the Po plain is an introgressed form of O. aurelia. According to this view, O. Aurelia and O. bertolonii are the ancestral forms, which appeared around the Toscana, and have been introgressed to various degree by various species in the periphery of their range leading to the appearance of new taxa such as O. saratoi, O catalonica or O. benacensis.
Yes, I already heard this theory, but I found no arguments supporting it about benacensis : introgressed by who ? why ? which character is concerned ? I can see no difference with aurelia...
About saratoi (and flavicans in Croatia), I cannot see more introgression (by who ?) but a good speciation process based on the size of labellum and then of pollinator insect. But for all the criteria, saratoi and flavicans are pure bertolonii s.l.
Inversely, O. catalunica/magniflora is clearly an introgressed entity, with a smaller, not erected and not turgescent, appendix. Also the macula is often influenced by the exaltata s.l.
Exactly strong support for O. catalunica, much less for O. benacensis.
The criteria, usually given for O. benacensis (besides range and habitat) are mainly the dimension of the labellum but these are of course variable.
Edit : And the higher complexity of the macula, which, I think, is the source of the peripherical introgression theory.
Yes, but he same macula variation exist in Provence for the "aurelia" (you can compare the photos from both countries on iNat)
Almost all the authors consider that O. (ssp.) benacensis from Lago di Garda and O. (ssp.) aurelia from Genova are synonym, because they share same morphology, same flowering time and also same pollinator (according to Paulus itself), plus a continuous distribution area.
- NB: Soca consider the typical O. bertolonii from Genvoa is also a synonym, and then the prioritary name, but this position is not followed neither by POWO, nor here -
Well, apart this nomenclatural controversy, if both are considered synonym, then O. aurelia is a priority name at species rank, but subsp. benacensis is the priority name at subspecific rank (according to the Code), the rank used here.
So, we should to swap the name O. b. aurelia, mostly used in France, into O. b. benacensis, mostly used in Italy.
@mercantour @chacled @fabienpiednoir @wolfgangb @tmaximo @joseproma : as the main observers/identifiers of this taxon, is it ok for you ?
