Discovery of the males of Lasioglossum (Eickwortia)hienae and L. (E.) alexanderi, with new distributional records for the species (Apoidea, Halictidae)

Within the diverse genus Lasioglossum, the subgenus Eickwortia as currently understood, encompasses three characteristic species from mountainous areas in Mexico and Central America. Prior to this work only Lasioglossum (Eickwortia) nycteris had descriptions for both male and female. Here we describe and illustrate the previously unknown males of L. (E.) hienae and L. (E.) alexanderi, providing new distributional data for both species, and an updated species identification key for the group.
