NOTES ON THE SUFFOLK LIST OF COLEOPTERA
85
On 22 May 2004, B. collaris occurred quite commonly to Mark Telfer at Cornard Mere S.W.T. Reserve, VC26 (TL8838) together with two examples in the old moat (TL8939). The species is not represented in the Morley Collection. LEIODIDAE *Colon zebei Kraatz RDBK It is likely that the species of this genus and subfamily breed in various underground fungi or moulds as do most of the Leiodinae. All species are rare. They are usually captured with the help of a flight interception trap, by evening sweeping or sometimes by pitfalling. On 30 May 1984, I swept a male of this very rare species near The Tower on the Shrubland Estate, Coddenham, VC25 (TM1253) (det. C. Johnson). The species is unrepresented in the Morley Collection. PTILIIDAE *Ptenidium intermedium Wankowicz Local This tiny beetle which occurs in damp marshy places and is found frequently in Phragmites and Carex litter has recently been found in both vice-counties as follows: 6 July 2004, 1 in litter, Hopton Fen, VC26 (TL9979) (teste C. Johnson). 10 August 2000, several from pitfalls in reedbed, Alton Water, Tattingstone Reservoir, VC25 (TM1338) (P. Lee; teste DRN/CJ). The beetle is unrepresented in the Morley Collection. PSELAPHIDAE Amauronyx maerkeli (Aubé) RDB3 This rarely recorded, intricately sculptured little beetle which is usually found in the company of ants, was placed on our list on the strength of a capture by a Miss Freeman from under leaves at Aspall Wood [VC25, TM1765] in 1861 and reported by Garneys (Morley, 1899). There appear to have been no other Suffolk captures since that time. According to Hyman & Parsons (1994) the beetle, although recorded from some 12 counties before 1970, has only been recorded from Surrey, Worcestershire and Denbighshire since 1969. I took a single example in a pitfall trap set a metre or so from the edge of the Decoy Pond at Brantham VC25 (TM1033) between 30 May and 13 June 2004. The boggy edges of the pond are fringed in most places with Aspen (Populus tremula L.) whose accumulated dead leaves form a thick carpet in many areas. There are no specimens in the Morley Collection. STAPHYLINIDAE Rugilus fragilis (Gravenhorst) Na This species usually occurs in marshes and damp places but is sometimes found in drier situations. It was included in Morley’s “Coleoptera” (1899) on the strength of published captures by Garneys, all made I suspect, in the same locality during the years 1859–1863 and perhaps later. Morley (op. cit.) quoting from Fowler, gives “Aspall Wood, Suffolk, taken in abundance by the
