NOTES

Phasia obesa (Fabricius)   is highly variable, especially for wing patterns, abdominal pruinosity and the shape of sheath (see Draber­Mońko 1965: 159­167 [figs: 322­357]).

This species is similar to the Nearctic species Phasia aeneoventris (Williston)   and Phasia robertsonii (Townsend)   , and the Neotropical species Phasia moerens (Wulp)   . Males of Phasia obesa   can be separated from these species on the basis of the distiphallus and pregonite, but no diagnostic character has been found for females.
