Saproxylic beetles of Ireland ____________________________ STAPHYLINIDAE SUBFAMILY TACHYPORINAE Sepedophilus littoreus (Linnaeus, 1758) – Scarce Mycetophagous species, feeding on fungal hyphae not fruiting bodies - rarely away from dead and decaying wood of some kind; occasionally found amongst leaf and other vegetable litter. Generally distributed in Britain, largely in ancient woodlands. Although not known prior to 1977, it seems probable that the species is an old woodland relict in Ireland (Anderson, 1978). H6 Waterford: Dunkitt Castle meadow, pitfall in riverine grassland, v.-vi, 1999, JAG. H19 Kildare: Pollardstown Fen, pitfall in fen, vi.1998, v.-vii.2002, JAG. H33 Fermanagh: near Inishteige, Upper Lough Macnean (H0242), female from roadside grass cuttings bordering freshly felled scrub woodland, 12.iv.1977, RA (Anderson, 1978); Inisherk, Crom, FIT, vi.- vii.1992, APF. H34 East Donegal: Dunkineely, from Polyporus squamosus on stump, 6.vi.1999, KNAA. H38 Down: Tollymore Forest, under piled up Douglas fir bark, 9.iv.1993, RA. H39 Antrim: near Portmore Lough (J119686), pair from under bark around fruiting fungus Phlebia merismoides on a rotting alder log in marginal old alder woodland, 24.xi.1984, RA (Anderson, 1985); Bucklebrook House, Upper Ballinderry, 31.iii.2011, MDB. H40 Londonderry: by Toneduff Bridge, R. Faughan (C5107), male in basidiomycete fungi on beech logs, 31.x.1977, RA (Anderson, 1978). STAPHYLINIDAE Subfamily ALEOCHARINAE Alaobia pallidicornis (Thomson, C.G., 1856) – Uncommon At sap, bracket fungi, and under fungoid bark in forest trees. Local and mainly south-eastern in Britain, but more generally distributed in Ireland. Possibly not an obligate saproxylic. H18 Offaly: Charleville Wood, Tullamore, in bracket fungus on horse chestnut, 24.v.2003, RCW (Regan & Anderson, 2003). H19 Kildare: Louisa Bridge, Royal Canal, in ‘Polyporus’ on poplar, viii.1942, EO (O’Mahony, 1943). H30 Cavan: Cloverhill, at sap of damaged oak, vi.1916, GWN (Nicholson, 1920). H33 Fermanagh: Rossyvullan Hill, Castle Coole, under fungoid bark on oak limb, 28.v.2010, RA. 28
Saproxylic beetles of Ireland ____________________________ H37 Armagh: Tynan Abbey Estate, in Polyporus squamosus on birch, 26.vii.2011, RA; Tynan Abbey, in Trametes on ash, 17.viii.2011, RA. H38 Down: Hydebank Woods, under fungoid bark of sycamore log, 25.x.2007, RA; Mount Stewart, in Russula under beech, 11.viii.2010, RA; Dundrum Castle (J406371), a pair in fungi on dead wood, 14.iii.2012, MDB. H39 Antrim: Glenarm Nature Reserve, in Piptoporus on birch, 8.vi.2011, RA. Atheta basicornis (Mulsant & Rey, 1852) – Scarce Under bark on periodically inundated dead branches and trunks along fast-flowing rivers; feeds on fungal material. H15 South-east Galway: Lough Coy Turlough, Ardrahan, pitfall, 6.v.1996, JAG. H18 Offaly: Bullock Island, Shannon, under willow bark, 24.v.2003, RCW (Regan & Anderson, 2003). H30 Cavan: Cloverhill, under pine bark, vi.1916, GWN (Nicholson, 1920). H33 Fermanagh: Rossyvullan Hill, Castle Coole, under fungoid bark on oak, 28.v.2010; Munilly Bridge, Old Ulster Canal, under willow bark, 19.vii.2011, RA. H37 Armagh: Oxford Island (J047621), in fungus on willow, 25.iii.2012, MDB H38 Down: Murlough NNR, in Agaricus campestris, dunes, 23.ix.2006, RA. H39 Antrim: Portmore Lough, under bark of willow and alder, 19.vi.2009, 26.vi.2009, RA. Atheta pilicornis (Thomson, 1852) – Rare Chiefly subcortical, often with scolytids; adults also reported from wood-decay and terricolous fungi, moss and among dead leaves, but larval habits not known; damp woodlands. H2 North Kerry: near Killarney, in dead leaves, vi.1932, EFB det. Ste. Claire Deville (Bullock, 1932). H38 Down: Belvoir Forest (J339696), 1 male in bolete Xerocomus chrysenteron under oak, 11.ix.1997, RA; Dundrum Castle woods, 1 female on Polyporus squamosus on horse chestnut, 20.vii.2009, RA. Bessobia fungivora (Thomson, 1867) – Rare In rotting fungi or on fungoid wood in forests; probably not an obligate saproxylic. Historically known only from a record of R.E. Dillon for Clonbrock, a specimen having been determined by J.N. Halbert (Johnson & Halbert, 1902). Dillon has become notorious for some of the outlandish records claimed for Clonbrock which, but for a modern record, would have made the species doubtfully Irish. H16 North-east Galway: Clonbrock, RED, det. JNH (Johnson & Halbert, 1902). 29
