Taxonomic history
This was originally described as Chrysodina opacicollis by Lefèvre in 1885. Flowers (1996) transferred South species formerly in Chrysodina to Metaparia as part of a broader revision of Eumolpinae . The North American species remained in Spintherophyta.
Identification challenges
in this group are difficult to identify from photographs alone. note that even with specimens in hand, confident identification to species level may not be possible without reference to material.
