Recognized species

There are 2 species currently in the genus (A. nodosa was moved to Timonidia by Emeljanov 2006):

Aridia compressa (Ball, 1909) [Metcalf 1946: 220] – USA: CA, NV, UT
Orgerius compressus Ball, 1909: 202.
Aridia compressa (Ball, 1909); comb. by Ball & Hartzell, 1922: 147.

Aridia erecta (Ball, 1909) – USA: AZ, CA, NV
= Orgerius erectus Ball, 1909: 202.
Aridia erecta (Ball, 1909); comb. by Ball & Hartzell, 1922: 148

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.  See also FLOW.

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).

Original description from Ball and Harzell 1922: 147:

Resembling Acinaca, but with a shorter, broader, more rounding cephalic process.

Cephalic process broad and short, rounding at the apex, slightly inclined upwards. Vertex broad, as wide as the eye, the median carina fades out before reaching the apex. Front narrow, with very sharply defined carinae; median carina of the front uniting with the lateral carina in a five-sided figure. Frontal tablet linear, inflated just below the eyes. No callosity behind the eyes, the eye and pronotum contiguous. Pronotum short, with median carina, without a central tablet, pustulate. Scutellum with central tablet, with three sharply defined carinae. Elytra brachypterous. Strongly reticulate. Abdomen ovate. Abdominal segments with a row of pustules along posterior margin two-thirds of the distance to the median line. Legs linear, not expanded.

Collecting

Collected infrequently, found by inspecting or sweeping hosts.

Molecular resources: 

As of this writing (1 Oct. 2018), data for this genus is not available on Genbank. Barcode of life has data on Aridia nodosa (a nymph), but this species was moved to Timonidia.
