opolasekDescription
This species is re-discovered after 136 years of presumed extinction, after a single (holotype) specimen was collected in 1885 (Natura Croatia, 2022;31(2):217-224, https://hrcak.srce.hr/en/clanak/417209 and Linzer biol. Beitr 2022:54(1):251-256; https://www.zobodat.at/pdf/LBB_0054_1_0251-0256.pdf). The main feature of the species is the black marking on the male clypeus. Females were firstly observed and described from this location. Currently considered endemic to Croatian coast, including the Mosor, Kozjak and Dinara Mountains.

Face off between two males.
I've never seen this particular form of confrontation before -- usually the bees seem to go for aerial attacks and wrestling, but it must be a behavior common in this species, as I witnessed them doing this more than once.
During breaks between pestering each other, they visited a stand of blooming Echium vulgare.
Another observation at the same site, presumably of the same species: https://www.inaturalist.org/observations/120992679
