Identification. Known from phoretic deutonymphs only. Similar to Ch. abditus and Ch. lithurgi. Differs from these two species by ratio length of prodorsal shield/length of seta d₁ (See key). Click here for multivariate discrimination between 3 cryptic species.

Hosts. Lithurgus (Lithurgopsis) gibbosus Smith, 1853

Distribution (show map). USA: Florida (type locality), Georgia.
