Abstract

Thirty species of Curculionoidea (28 Curculionidae and one each of Brentidae and Nemonychidae) are reported as new records from the Canadian province of Newfoundland and Labrador, most of them from the island of Newfoundland. As well, 13 species of Curculionidae and one of Brentidae previously recorded from Newfoundland are newly reported from Labrador, and one Curculionidae previously recorded from Labrador is newly reported from Newfoundland. The Palearctic species, Orthochaetes setiger ([Beck]), is herein reported as a new Canadian and North American record, with specimens documented from Newfoundland and British Columbia. Additions to the primary key for North American weevils are provided to help identify this genus among the North American fauna. Of the species of Curculionoidea previously recorded from the province in published literature, there is uncertain evidence for the occurrence of 14 species in the province as a whole or in the Labrador portion. Seven species are hereby removed from the faunal list for the province. One of those, Trachodes hispidus (Linnaeus), is also removed from the Canadian faunal list. The 134 species of Curculionoidea recorded from NL are listed and a brief synopsis of the fauna provided.
