Distribution
In England, the species is known from one site in Cambridgeshire. It has also been recorded subsequently from Germany (Blick & Hanggi 2000; Sacher & Breinl 1999).Habitat and ecology
Arable fields. Although not greatly reduced the eyes are small, supporting the view that the spider may live in fissures below the surface of the ground. The species does appear to be related to a group of cave-dwelling Centromerus species from southern Europe (Merrett, Powell & Maher 1993). Males were collected during the period 9th January to 19th March 1992. In spite of further pitfall trapping and hand searches at the original site, females have not been found, nor indeed any further males. More recently, subterranean traps were deployed over winter 2006/7 in arable fields within a kilometre of the type locality, targeting this species, but without success.Status
Nineteen males were collected by pitfall trapping in a single field of winter wheat and described as new to science (Merrett, Powell & Maher 1993).Threats
