Allothrombium sp., photographed by Jesse Rorabaugh.

Belongs within: Trombidiidae.

The Allothrombiinae are a cosmopolitan group of trombidiid mites with large, colourful adults, characterised by the present of a brush-like empodium in association with the tarsal claws.

Characters (from Thor 1935): Adult large, with strong shoulders, rounded, with bristle-like plumose, rarely branched, setae. Two eyes each side of prosoma on long movable stalks. Crista tripartite, broadened at or behind the middle, pitcher or heart-shaped, with large lateral areoles for the two sensilla. Palpi large, with large tibial claw, without secondary claw or comb. Legs short or medium length, brush-like empodium on tarsus, either a pulvillus between the claws or brush-like bristles adjacent to the claws.
