Dorsal cuticular folds of ambulacra I-III weakly developed, with distal part smaller than proximal.

Genital setae distinctly (more than their diameter at base) anterior to progenital sclerites .

[1] A dichotomous key to phoretic deutonymphs is available from the bee-associated mites website and Klimov and OConnor, 2008.

As mutualists or commensals, they feed on nest materials, fatty acids from floral oils, and most likely, on fungi harmful to the bee larvae.

Deutonymphs of Roubikia panamensis and R. imberba can also be found dispersing on kleptoparasitic bees of the genus Coelioxoides (Apidae: Tetrapediini).

[3] For Roubikia, Coelioxoides bees may serve as transport, dispersing the mites to different nests of Tetrapedia.

[4] A single species, Roubikia latebrosa, is phoretic in the metasomal acarinarium of the host.
