Holotype in UMMZ, paratypes in AMNH, GRSM, OSAL, UMMZ, UNAM.
Identification. See key. Known from phoretic deutonymphs and adults.
Hosts. Hoplitis (Alcidamea) producta (type host); Hoplitis (Alcidamea) pilosifrons; Hoplitis (Monumetha) spoliata; Megachile (Megachile) relativa; Osmia (Melanosmia) brevis; Osmia (Centrosmia) bucephala; Osmia (Chenosmia) inermis (Megachilidae); Isodontia mexicana (Hymenoptera: Sphecidae)
Distribution (show map). USA: Idaho, Maine, Michigan, New York (type locality), North Carolina, Ohio, Oregon, Tennessee, Wisconsin; Canada: Quebec.
Etymology. The specific epithet is derived from the generic name of the host and is a noun in the genitive case.
Notes. The association of Ch. hopliti and the non-Hoplitis hosts (see above) is probably accidental. Because these insects construct their nests in the same habitat as Hoplitis, it seems possible that deutonymphs of Ch. hopliti may accidentally attach to them.
