Summary details for Gongylidiellum murcidum Simon, 1884

Species Details

Species name: Gongylidiellum murcidum Simon, 1884
Taxonomy: Animalia :: Araneae :: Linyphiidae
habitat: acid & sedge peats

Distribution

The species is widespread in East Anglia, but otherwise there are few very widely scattered records. It is widespread in north-western and central Europe, with records from France and Switzerland to Hungary.

Habitat and ecology

This species is usually found among wet moss and litter in fens, sometimes in fen carr or in other wet broad-leaved woodland. In Staffordshire, it has been taken in reed-beds and a floating bog (C. Slawson, pers. comm.). Our very limited phenology data indicate a possible peak in adults in late spring/early summer.

Status

The species has been fairly numerous at some sites, but seems to have undergone a substantial decline since the 1970s.

Threats

The most serious threat is from the drainage of fens and wet woodland.

Management and conservation

It is important to maintain the water table in fens and wet woodland. The growth of scrub in fens is probably not as detrimental to this species as to other fenland species. Text based on Dawson, I.K., Harvey, P.R., Merrett, P. & Russell-Smith, A.R. (in prep.).

A Review of the scarce and threatened spiders (Araneae) of Great Britain: Species Status No. 22 (Sep 2017)	Red listing based on 2001 IUCN guidelines	Vulnerable	01/09/2017	This wetland species has been recorded at 10 locations since 1993, most recently in 2011. It has exhibited a substantial decline in AOO. There appears to have been a contraction in range, with no records from Scotland since 1988. It is normally found in wet moss and litter in fens and wetwoodland where the main threats are drainage of fens and loss of wet, deciduous woodland through drainage or removal of trees. Threats: The most serious threat is from the drainage of fens and wet woodland.
