A very small population although with a wide area of extension in warm-temperate regions.
Two current records; a large species that is unlikely to have been overlooked. Stochastic events are a considerable threat. Although mostly in anthropogenous sites it also occur in nature (eg Gran Canaria).CR-EN (D1) suggested
In warm-temperete areas. North America (Pennsylvania; records dating back to the beginning of the 1900); France 1884-1902, Great Britain 1883; Most recent European records in Italy 1980, France 1990, Czech Republic 2015. Also known from Macaronesia (Gran Canaria 2010) and Japan (1986).
Was considered introduced to Europe by Kreisel (2001).
Very small current population (latest records 2012 and 2015). Most records in man-made habitats.
Most records out-dated; only recent records in Gran Canaria 2010 ans the Chech Republic 2015.Including all records: EOO: 9,000 000 km2, AOO 72 km2
Including records 2000-2025; (2 records): AOO 8 km2Estimated number of localities: 10
Estimated number of mature indivuduals: < 50
Population Trend: Uncertain
Saprotrophic and thermophilous species found on self-heating substrates (spent tan, wood chips, saw dust), rarely in sandy habitats under more natural circumstances (Gran Canaria).
A very small current and historical population although with a wide area of extension in warm-temperate regions.
Two current records; a large species that is unlikely to be overlooked. Stochastic events are a considerable threat.
Monitoring of known localities
Dedicated discovery missions in suitable habitats.
