Cornish Red Data (2009)

The descriptive text, below the map, is from the Cornish Red Data Book (2009). The map on this web page depicts the organisms distribution and shows the records made pre-2000 and those made since.

Stenamma debile



Range & Status

This species is very local in southern England, the Midlands, Wales and southern Ireland. Formerly all British specimens were identified as S. westwoodi , but B. Bolton discovered that this taxon comprised two species S. debile and S. westwoodi . This genus has been revised by Dubois (1993).

Regional Distribution

In the RDB 1997, the Mellors referred to the record of this species (taken by them as a winged female on a slipway at Porthgwarra, near Land' s End in 1991) as S. westwoodi . S. westwoodi has also been recorded from the Isles of Scilly where it has been recorded from all five inhabited islands by Ian Beavis. In fact, all records from these areas are now considered as S. debile . It has been found in 2007 at Gweek by Paul Gainey and near Loe Pool by Ian McClenaghan. The current status of five 1km squares represents a significant increase on its 1997 status. This species is undoubtedly under-recorded; records can be obtained by sampling leaf litter. S. westwoodi occurs just north of Plymouth, which may be the nearest record to Cornwall.
