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).
