NOTES

Draber­Mońko (1970 and pers. comm.) noted that the holotype of this species was housed in the Museum für Naturkunde der Humboldt­Universitat (ZMHU), Berlin, Germany. At this time, however, it cannot be located (H. Schumann, pers. comm.).

Phasia emdeni (Draber­Mońko) is similar to Phasia pandellei (Dupuis) , but differs in the structures of female sternite VII (sheath) and hind tibia bristles.
