- Fitchiella rufipes Lawson, 1933 – USA: AZ, CA, NM, NV, TX, UT; Mexico (Chihuahua)
- Fitchiella rufipes – Eragrostis curvula (Schrad.) Nees; (Weeping lovegrass; Poaceae (from Wilson & Wheeler 2010); Xanthocephalum sp. (Asteraceae) from Foster et al. 1981.
- Fitchiella robertsoni – Orbexilum onobrychis; dry barrens on hilltops and upper slopes associated with Orbexilum pedunculatum, Desmodium spp., Lespedeza, Tephrosia virginiana
Hosts from Wilson & Wheeler 2010, Foster et al. 1981; plant names from USDA PLANTS.
Genus is distinctive, head with weevil-like snout (similar to Bruchomorpha); front and middle legs modified. Species features more difficult – Doering (1941) provides key, but she did not have all species available to her; some taxa require comparison with known specimens or review of original descriptions.
