Ophrys dinarica


O.
dinarica was first described by Kranciev and Delforge from Lika, Croatia in 2004 and its name refers to  its discovery in the vicinity of Mount Dinara. It's a member of the 13 strong O. tetraloniae  group which take their name from the tetralonia genus of bees representing the most significant pollinators of this family of Ophrys.
 
As far as was thought, O. dinarica could only be found locally in
the valleys around Mount Dinara in Croatia  but although its precise range is still not known with certainty, it has now been established that it occurs  more widely in several area's of peninsula Italy. In both central Italy and Croatia it joins several other of its fellow group members and unsurprisingly, natural variation and hybridisation create considerable identification challenges.

Identifying key characteristics that can yield a certain diagnosis is difficult and there are few features that could not be equally present in other group members. Amongst those that tend to be more pronounced in O. dinarica is the multi toothed appendage which is extremely well developed and the column which is usually  elongated. The basal swellings are generally robust, conical and yellow on the inside, the lip is globular and may be strongly scolopaxoid. The speculum is highly variable and can range from an extensive, confused  pattern (frequent) to candicoid. In Croatia a  significant proportion of the species exhibit a split basal field which form two oval segments, this feature does however seem rarer in the Italian populations where the split is less distinct and the central division little more than a weak W or absent altogether. The pictures are from Umbria and Abruzzo in Italy and the war ravaged Drnis region of Croatia.
