Taxonomy and species list

The four species now placed in this genus were formerly assigned to the genus Hemispingus. A molecular phylogenetic study published in 2014 found that Hemispingus was polyphyletic and as part of the subsequent rearrangement, the genus Sphenopsis was resurrected for these four species.[1][2][3] The genus had been introduced in 1862 by the English zoologist Philip Sclater with the type species as Sphenopsis ignobilis, a taxon that is now treated as a subspecies of the oleaginous hemispingus.[3][4] The name Sphenopsis combines the Ancient Greek sphēn meaning "wedge" with opsis meaning "appearance".[5]

The four species in the genus are:[3]
