Distribution in Canada and Alaska.

NB ( Bousquet et al. 2013). Hadreule elongatula   (Gyllenhal) is widespread throughout Europe, Siberia, and North Africa ( Lawrence 1971). Lawrence (1971) hypothesized that the species would have a broader distribution in North America, but in the subsequent decades, it has been found only in NB, where it was first reported by Pielou and Verna (1968) from specimens reared from Piptoporus betulinus   (= Polyporus betulinus   ) at two localities (reported above). It was probably introduced from Europe ( Lawrence 1971). All recent records of this species from NB were based on specimens captured in Lindgren funnel traps. This species is widespread (seven localities) and fairly common in the province. This adventive species was captured mostly in conifer forests in NB.

Taxonomic notes.

It is worth mentioning that the correct spelling of the genus name is Hadreule   , not Hadraule   (see Orledge and Booth 2006). In several works, the publication date of this genus, described by Thomson, was cited as being 1863. In Thomson (1863) the spelling is " Hadraule   ". However, the name was indeed proposed four years before by the same author, but spelled as " Hadreule   " ( Thomson 1859: 91). Therefore, " Hadraule   " is an incorrect subsequent spelling.
