Edaphus lederi Eppelsheim, 1878† Fig. 42

Material examined.

Canada, New Brunswick, York Co., Charters Settlement, 45.8395°N, 66.7391°W, 5.IX.2009, R.P. Webster, coll. // Mixed forest, in pile of decaying corncobs and cornhusks (1, RWC); same locality and habitat data but 3.IX.2010 (4, RWC).

Distribution in Canada and Alaska.

NB (new Canadian record). Puthz (2010) synonymized Edaphus beszedesi Reitter (Type locality Lincoln, Nebraska ( Reitter 1914)) with Edaphus lederi , so all previous records of Edaphus beszedesi are Edaphus lederi . Puthz considered this species to be Palaearctic and adventive to North America and reported it from IL and KS in the USA. There is an additional specimen in CNC determined by Puthz from AL, indicating that this species is widespread in the USA. This species is widespread in central and southern Europe and may have been introduced into North America with leaf litter or other vegetable debris ( Puthz 1974). Puthz (2010) reported it from Taiwan, where it is adventive. This is the first record of this genus for Canada.

Natural history.

The five specimens of this species from NB were sifted from a pile of decaying, moldy corncobs and cornhusks in September. It was reported from a corncob pile in IL and decaying vegetation in KS ( Puthz 1974).
