Chrysis impressa Schenck,1856

Description and notes

Disagreement exists considering the definition of this name. Linsenmaier (1997) treats this taxon as a subspecies of C. ignita. Kunz (1994) considers C. impressa to be a synonym of C. ignita. Morgan (1984) regards C. impressa as a separate species from C. ignita. Here it is meant in the sense given by Morgan (1984).
