Rhysodidae
Rhysodes sulcatus (Fabricius) – Fossil. In thoroughly rotten timber where it is thought to feed
on fungi, most often in beech Fagus; no modern records from British Isles, most
recently known c3000 BP; sub-fossil records from Somerset Levels and East Anglia
(early Holocene). A relict species of primary, wholly undisturbed forest, ie before it
has been disturbed by human activity. Extremely rare and mainly a southern
European species, from the Pyrenees to the Caucasus, extending northward through
Hungary and Austria to southern Germany; last recorded in Sweden in 1863, and the
few German records are old.
Histeridae - Hister Beetles. Predatory, especially on larvae of other deadwood insects, also
mites and springtails.
Teretrius fabricii Mazur - RDB1. Preys on larvae of the beetles Lyctus brunneus, L. linearis
and L. fuscus and other bostrichoids; majority of records from fresh oak Quercus
palings. 19C records London, W. Glamorgan, Norfolk, Bristol, W. Sussex, and most
recently Surrey in 1907.
Plegaderus dissectus Erichson - Nationally Scarce B. Confined to ancient wood pastures;
lives in moist crumbly decaying timber of various broad-leaved trees, and
occasionally found under sappy bark; central southern and eastern England, north up
to Nottinghamshire, but absent from west.
Plegaderus vulneratus (Panzer) – Naturalised. Under bark of dead conifers, occasionally
broad-leaved trees; association with bark beetle Hylastes attenuatus has been
suggested; first discovered in Britain in 1962.
Abraeus perpusillus (Marsham)* =globosus (Hoffman, J.) - In moist rotten wood of various
broad-leaved trees; usually ancient woodland or wood pasture, especially in the west;
widespread but local throughout much of England, except far north and west. Rare in
Wales and Ireland.
Abraeus granulum Erichson - Nationally Scarce A. In moist crumbly rotten wood of various
broad-leaved trees; sites are typically ancient wood pastures. Scattered from southeast
to East Anglia and across to Mersey.
Aeletes atomarius (Aubé) - RDB3. Usually in burrows of lesser stag beetle Dorcus
parallelopipedus in moist crumbly decaying heartwood, although also recorded with
Sinodendron cylindricum and brown tree ant Lasius brunneus; in beech Fagus, ash
Fraxinus, willow Salix, alder Alnus. Ancient wood pastures; mostly central England,
to Yorkshire in north and Hampshire and Kent in south-east.
Gnathoncus buyssoni Auzat - Nationally Scarce A. A scavenger, living particularly in the
nests of birds within hollow trees, but also in squirrel dreys and other situations.
Widespread across the lowlands of southern Britain, but very localised within its
range.
Gnathoncus nannetensis (Marseul) - Most often found in the nests of birds within hollow
trees, but also in a variety of other situations. Uncommon.
Gnathoncus nanus (Scriba) - Most often found in the nests of birds within hollow trees, but
also in a variety of other situations. Uncommon.
Gnathoncus schmidti Reitter - Most often found in the nests of birds within hollow trees,
rarely in other situations. Uncommon.
Dendrophilus punctatus (Herbst) - Most often found in the nests of birds within hollow trees,
but also in a variety of other situations, including the nests of wood ant Formica rufa.
Uncommon.
Paromalus flavicornis (Herbst) - Associated with debris beneath bark on deadwood of
medium age, and sometimes in the rotten wood and fungi; larvae feed on smaller
larvae; broad-leaved trees generally; local, mostly old parks and ancient woodlands in
