Taxonomic notes.

Lasioglossum auratum is the type species of Habralictellus, a genus group that has fluctuated between treatments as a genus (Moure and Hurd 1982; Engel 2001b), subgenus of Lasioglossum (Gibbs 2016, 2018; Genaro 2021), or a synonym of L. (Dialictus) (Michener 2000; Genaro 2001b, 2016). Preliminary molecular phylogenetic data suggests L. (Habralictellus) is distinct from L. (Dialictus) (Gibbs 2018). The differences in size, sculpturing, and male genitalia evident in described L. (Habralictellus) suggests that it may not be monophyletic (Gibbs 2018).
