Recorded altitude range

Species text

Distribution
The species has been recorded only from Surrey, West Sussex and Hampshire. The distribution in Europe is poorly known, but it has been recorded from Sweden, Germany, Switzerland and Austria.

Habitat and ecology
The spider occurs in moist places at ground level on heathland, under stones or among damp, dead Molinia caerulea litter between the tussocks. It has been found at between 700 and 1500 m in Austria and Switzerland. Males are adult in April, females continuing until end of May.

Status
Lathys nielseni was recognised in Britain as a species separate from L. humilis (Blackwall) only in 1984, but there have been few records since that time, and it seems likely that it is confined to heathland in a small area of south-east England. Recorded from a total of four locations prior to 1992 but not recorded since that date.

Threats
The loss of heathland to agriculture, afforestation and development.

Management and conservation
Maintain all seral stages of heathland by rotational management.
