Adult Camerotrombidium simile, with close-ups of setae, from Southcott (1994).

Belongs within: Microtrombidiidae.

Camerotrombidium is an Old World genus of microtrombidiid mites with distinctive cup-shaped idiosomal setae in the adult (Southcott 1994).

Characters (from Southcott 1994): Adult middle-sized with well-developed crista, extending only a little behind the sensillary enlargement. Eyes two on each side, subequal, each pair on a small ocular plate. Idiosomal setae arising from well-developed papillae, generally short, chambered, spherical or ovoid, finely setulose, with the extremity an open chamber, hence cup-shaped, not bent over. Palpal tibia with odontus, paradont (one or more), one or more ctenidia, and additional spinisetae. Legs of middling length; tarsi often enlarged, particularly of leg I. Larva with two scuta on dorsum of idiosoma, both with fine longitudinal striations. Anterior scutum with six scutalae and two sensillary setae; lateral border slightly concave. Eyes subequal, each lateral pair on a small ocular plate. Posterior dorsal scutum with two scutalae. Four dorsal idiosomal setae behind posterior dorsal scutum arise from small oval plates; other dorsal idiosomal setae with unexpanded annuli. Coxalae 2, 1, 1; formula BB, B, B. Tarsal claws 3, 3, deformed; claws of I and II simple, without subterminal spurs. Hypostomala short, expanding, with several terminal blunted digitations.
