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).
