Résumé
Les chilopodes (ou cent-pattes) sont des prédateurs actifs qui passent souvent inaperçus à cause de leur mode de vie principalement cryptique. Seulement 4 espèces sont officiellement connues au Québec, mais cette faune ayant été très peu étudiée dans l’est du Canada et en Nouvelle-Angleterre, le nombre réel d’espèces est probablement sous-estimé. Nous présentons ici les 3 premières mentions dans la famille des Henicopidae au Québec, dont 2 nouvelles espèces pour le Canada. Ces mentions contribuent à agrandir considérablement l’aire de répartition vers le nord de Lamyctes pius Chamberlin, 1911, et de Zygethobius pontis Chamberlin, 1911, qui étaient jusque-là principalement connues entre la Géorgie et la Pennsylvanie, avec quelques rares mentions dans l’État de New York.

Abstract
Centipedes are active predators, but due to their cryptic behaviour, they generally go unnoticed. Until the present study, only 4 species were known to occur in the wild in Québec (Canada). However, as few inventories in eastern Canada and New England have focused on this group, this number was felt to be an underestimation. The present article provides the first records for Québec of 3 species from the family Henicopidae, including 2 new mentions for Canada. The latter also represent the northernmost known occurrences of Lamyctes pius Chamberlin, 1911 and Zygethobius pontis Chamberlin, 1911, which are mainly distributed from Georgia to Pennsylvania, with a few records from the State of New York.
