Names
Scientific source:

Isodontia (Isodontia) exornata Fernald (Figs. 19, 66) Isodontia exornata Fernald, 1903, Canadian Ent., 35:270. Lectotype ♀, “Ga.” (USNM). Present designation.


Geographic distribution
Distribution.—I. exornata occurs in the southeastern United States (Georgia, Florida, Alabama) and ranges west to Texas (fig. 19). Murray (1951) reported it also in North Carolina.

Natural history
This species is closely related to I. fuscipennis (Fabricius) but the key characters readily separate them. We have seen females of what appear to be exornata from Mexico, but the antennae are dark, the wings and body lighter, and the appressed pubescence is not so coppery. These may represent a distinct subspecies.
