Genus Aridia Ball & Hartzell, 1922
Family Dictyopharidae
Subfamily Orgeriinae Fieber, 1872
Tribe Orgeriini Fieber, 1872
Genus Aridia Ball & Hartzell, 1922
Type species (in original combination): Orgerius compressus Ball, 1909.
Synonyms: None.
Distribution: Southeastern US.
Recognized species
There are 2 species currently in the genus (A. nodosa was moved to Timonidia by Emeljanov 2006):
Aridia compressa (Ball, 1909) - USA: CA, NV, UT
Aridia erecta (Ball, 1909) - USA: AZ, CA, NV
Economic Importance:
Limited.
Known host plants:
Aridia compressa - Artemisia tridentata Nutt.(big sagebrush, Asteraceae)
Hosts from Wilson et al. (1994); plant names from USDA PLANTS or Tropicos.
Recognition:
Brachypterous, leaving several terga visible from above, tegulae hidden (all Orgeriinae); no callosity behind eye; head weakly angulate in lateral view, produced in front of eyes for distance less than 2/3 width of eyes, narrowed toward apex in lateral view; front without horizontal black band above frontoclypeal suture; tibiae not enlarged; areolet at apex of head well defined, pentagonal, enclosed by sharp carinae.
Keys to genus of US Orgeriinae in Doering & Darby 1943 and Doering (1955), although Emljanov (2006) revised some generic concepts (including moving A. nodosa to Timonidia).

Aridia is not present on Bugguide.
Collecting
Collected infrequently, found by inspecting or sweeping hosts.
Molecular resources: As of this writing, data for this genus is not available on Genbank. Barcode of life has data on Aridia nodosa, but this species was moved to Timonidia
