Hylaeus euxanthus
Yellow-collared Masked Bee
A small, nearly hairless bee in the family Colletidae, native to Australia and introduced to Argentina. First described by Cockerell in 1910, it was originally named Prosopis xanthopoda but renamed due to preoccupation. It belongs to the subgenus Gnathoprosopis and exhibits typical masked bee characteristics including reduced pilosity and internal pollen transport.
