Distribution in Canada and Alaska.

BC, QC, NB ( Bousquet et al. 2013). All new records of Dolichocis laricinus   ( Mellié) from NB were based on specimens captured in Lindgren funnel traps. This species is currently known from three localities in NB. Specimens were captured in jack pine forests ( Pinus banksiana   Lamb.) at two localities and a mixed forest. These are the first records of this species from the Maritime Provinces.

Taxonomic notes.

The genus Dolichocis   Dury has only four species: Dolichocis indistinctus   Hatch and Dolichocis manitoba   Dury from North America, the Eurasian Dolichocis laricinus   ( Mellié), and Dolichocis yuasai   ( Chûjô) from Japan. The possible synonomy of Dolichocis indistinctus   Hatch and Dolichocis laricinus   was first proposed by Lawrence (1971). The type locality of Dolichocis indistinctus   (Stanley, BC) is close to the northwestern coast, but the species has a broad distribution in North America, and there is currently no doubt about its identification. The type locality of Dolichocis laricinus   is Paris (France), and specimens from Poland and France were available for comparison. A male Dolichocis indistinctus   from NB was dissected, and its aedeagus is exactly the same as in European specimens of Dolichocis laricinus   . Specimens of Dolichocis manitoba   were also examined and dissected, confirming that its male genitalia are quite distinct from those of Dolichocis indistinctus   and Dolichocis laricinus   . Unfortunately, no Dolichocis yuasai   were available, and no opinion can be given on this species. As Dolichocis indistinctus   is well within the morphological limits of Dolichocis laricinus   , we propose their synonymy. The species has a Holarctic distribution. In North America, it occurs on the same host fungi of Dolichocis manitoba   Dury, but Dolichocis laricinus   appears to be much rarer ( Lawrence 1971).
