Classification

Superorder Acariformes » Order Trombidiformes » Suborder Prostigmata » Infraorder Eleutherengona » Hyporder Raphignathina » Superfamily Tetranychoidea » Family Linotetranidae

Common names

cryptic false spider mites

Probability of encounter

low

Quarantine importance

Low. The Linotetranidae are associated with soil and grasses around the world. None are known to be important plant pests.

Diagnosis

  • Empodium with tenent hairs
  • Prodorsum with 4 pairs of setae (vi, ve, sci, sce)
  • Adult female with 3 pairs of anal setae (males with 5 pairs of ano-genital setae)
  • Cheliceral bases adnate, fused mesally into a stylophore (sometimes withdrawn into the body); chelicerae with fixed digit reduced and movable digit whiplike.
  • Peritremes typically chambered structures on the dorso-lateral surface of the prodorsum; naso absent; prodorsal trichobothria absent; 2 pairs of eye lenses usually present. Palps 5 segmented; usually (except Anoplopalpus) with thumbclaw process (claw-like seta on the palp tibia and a thumb- or button-like subterminal palp tarsus). Leg tarsi usually with tenent hairs on claws or empodium. Genital papillae absent; males with an intromittent aedeagus.

Similar taxa

Linotetranids resemble other elongate Tetranychoidea associated with grasses such as Allochaetophoridae (which have eyes) and some Tenuipalpidae (which lack a thumbclaw process and usually have eyes).

Ecology and distribution

The Tetranychoidea are plant-associated mites, and includes the infamous spider mites (Tetranychidae). Tetranychoid species that feed on grasses or pasture legumes may occasionally appear in soil samples.
