Trichocyclus arabana Huber 2001 Arabana Trichocyclus

Trichocyclus is noted for its unparalleled success and affinity for desert environments where it can be found under and between rocks, at the base of vegetation, cliff overhangs, caves and wells, inside termite mounds, pretty much anywhere it can escape direct sunlight and drying winds. The species is named for the Arabana (Ngarabana), an aboriginal tribe of the Lake Eyre area, South Australia. Widely distributed across the south western inland half of the mainland including southern Northern Territory, eastern Western Australia and much of South Australia. ♀ 2.5-4.5mm ♂ 2.5-4.5mm.
