Carpelimus erichsoni (Sharp, 1871)† Figs 18-19

Material examined.

Canada, New Brunswick, York Co., Charters Settlement, 45.8395°N, 66.7391°W, 26.IX.2008, 19.V.2011, R.P. Webster // Mixed forest, in decaying (moldy) corncobs & cornhusks (1 ♂, HNHM; 3 ♂, RWC).

Distribution in Canada and Alaska.

NB (New North American record). Schülke and Smetana (2015: 786) list this species from much of southern Europe from Russia (Southern Territory) and Yugoslavia south to Algeria and east to the Netherlands and Belgium. Callot (2013) recently cited a record from France, but this was not accepted/seen by Schülke. This species is adventive to NB, possibly via the Mediterranean region, although this is not the typical source of adventive species in the region.

Natural history.

All NB specimens were collected in May and September from decaying (moldy) corncobs and cornhusks, near a plastic composter.

Comments.

Carpelimus erichsoni is very similar externally to Carpelimus bilineatus Stephens (also an adventive species) but has differently shaped internal structures of the aedeagus ( Makranczy 2002, Gildenkov 2015).
