Hylaeus (Spatulariella) hyalinatus milossus ( Warncke, 1981)

This taxon is known only by its original description in which it was described as a subspecies of Hylaeus hyalinatus . It was raised to species level on the portal Westpalbees by Kuhlmann et al. (2022), without justification. This taxon is probably a junior synonym, most likely of H. longimacula (Alfken, 1936) . Awaiting for a revision of the Spatulariella subgenus, we leave it as an unclear subspecies of H. hyalinatus .
