Ellescus bipunctatus
Stephens, 1829
Ellescus bipunctatus is a Holarctic in the tribe Ellescini. A recent taxonomic revision designated a for this species and established E. borealis as its junior synonym. It is one of four valid Ellescus species in North America, where it occurs alongside the widespread E. ephippiatus, the west coast E. californicus, and the newly described E. michaeli. The species has been distinguished from using integrative combining morphological and molecular data.
