Body globular. Prodorsum with 4 pairs of setae (le, exa, in, exp) and 2 pairs of filiform trichobothria (bo, ro); ro with latch-like seta le; naso without setae; one pair of lateral eyes and median eye usually present. Labrum tubular, elongate and well sclerotised; chelicerae weakly dentate, each with 2 setae; rutella simple or highly modified; 2–3 pairs of adoral setae and 3 pairs of hypostomal setae; palps with 4–5 free segments. Opisthosoma hypertrichous, setae typically dendritic; 2–3 pairs of genital papillae.
The empodial claw of nanorchestid mites has a swollen basal region densely covered in setules and a smooth distal claw, and resembles the empodial claw of Alycosmesis (Terpnacaridae). Species of Nanorchestes are diverse and abundant in beach sand, dry forest soil, grasslands, mosses, and dry and cold deserts, and are the dominant form of animal life in Antarctica.
Neonanorchestes is identical except for having one clavate pair of trichobothria.
