Abstract

Seventy-three species of the acalyptrate family Sphaeroceridae are recorded from Canadian peatlands, largely on the basis of pan trap samples from peatlands in southern Ontario, the Yukon, and Alberta. Spelobia nana (Rondani), Spelobia ibrida (Roháček), and Trachyopella atomus (Rondani) are newly recorded from North America. Fifteen species are identified as characteristic of peatlands, and their distributions and relationships are discussed. Southern peatland populations of several of these species are interpreted as relict populations in peatlands serving as post-Pleistocene refugia. Some species are known so far only from peatlands along the postglacial fringe.

Résumé

Soixante-treize espèces de Sphaeroceridae, une famille de diptères acalyptères, ont été trouvées dans les tourbières canadiennes, la plupart capturées au moyen de pièges à cuvettes, dans le sud de l’Ontario, au Yukon et en Alberta. Spelobia nana (Rondani), Spelobia ibrida (Roháček) et Trachyopella atomus (Rondani) sont mentionnées pour la première fois en Amérique du Nord. Quinze espèces sont considérées comme caractéristiques des tourbières et leur répartition ainsi que leurs affinités sont examinées. Les populations de plusieurs de ces espèces dans des tourbières du sud semblent représenter des populations reliques des tourbières-refuges de la période post-Pléistocène. Certaines espèces n’ont été rencontrées à ce jour que dans les tourbières de la bordure post-glaciaire. [Traduit par la Rédaction]
