The following species of Curculionoidea are newly recorded from the Canadian province of Quebec: Coelocephalapion emaciipes (Fall, 1898); Ischnopterapion virens (Herbst, 1797); Omphalapion hookerorum (Kirby, 1808); Perapion punctinasum (J.B. Smith, 1884) (all Brentidae); Anthonomus robustulus LeConte, 1876; Pseudanthonomus helvolus (Boheman, 1843); Bagous magister LeConte, 1876; Bagous tanneri O'Brien, 1979; Buchananius striatus (LeConte, 1876); Ceutorhynchus bolteri Dietz, 1896; Ceutorhynchus pallidactylus (Marsham, 1802); Ceutorhynchus pauxillus Dietz, 1896; Conotrachelus buchanani Schoof, 1942; Conotrachelus pusillus LeConte, 1878; Conotrachelus recessus (Casey, 1910); Curculio rubidus (Gyllenhal, 1835); Cylindrocopturus longulus (LeConte, 1876); Hadroplontus litura (Fabricius, 1775); Hypera rumicis (Linnaeus, 1758); Lixus terminalis LeConte, 1876; Myosides seriehispidus Roelofs, 1873; Phloeotribus dentifrons (Blackman, 1921); Plocamus echidna (LeConte, 1876); Scolytus muticus Say, 1824; Sirocalodes sericans (LeConte, 1876); Smicronyx sculpticollis Casey, 1892 (all Curculionidae). Among these, Buchananius striatus, Conotrachelus buchanani, Conotrachelus pusillus, and Curculio rubidus (all Curculionidae) are also recorded from Canada for the first time. The latter is also newly reported from Ontario. Collecting data are provided for Lixus punctinasus LeConte, 1876, previously reported to occur in Canada without any further information, and for Choragus sayi LeConte, 1876 (Anthribidae) and Rhyssomatus aequalis Horn, 1873 (Curculionidae), both previously recorded from Quebec, also without further details.

Introduction

Douglas et al. (2013) recently reported five and 29 species new to Quebec (of which 3 and 11 were new to Canada, respectively), increasing the total number of species of each family known to occur in the province to 22 and 386, respectively (Bousquet et al. 2013). Recent collection efforts, mainly by amateur entomologists, have since yielded new findings. The new records and new documented record ( LeConte, 1876) reported herein (4 and 23 ), listed according to the classification of Bouchard et al. (2011), bring these totals to 26 and 409, respectively. Additions to the province’s weevil fauna will undoubtedly be recorded in the years to come not only due to increased collection efforts, but as more species continue to expand their range northwardly under present global warming conditions or are being introduced from other countries. Among the species newly reported here, (Herbst, 1797), (Kirby, 1808), (Marsham, 1802), PageBreak (Gyllenhal, 1835), (Fabricius, 1775), Roelofs, 1873, and (Linnaeus, 1758) are all adventive species (sensu Wheeler and Hoebeke 2009) that were accidentally introduced in Canada or intentionally brought in as biological control agents.

Materials and methods

Specimens belonging to species recorded or referred to in the present article were identified (or their identity was confirmed) by recognized specialists listed henceforth under each species name by their name, or if an author of this paper, by their initials.

Label data are provided in chronological order for every species. These data were translated from French to English, and various details (e.g., current regional county municipality [MRC], collecting technique, general habitat), when known, have been added between brackets.

Specimens were either swept or beaten from various plant species, attracted to mercury vapour, ultraviolet or porch lights or handpicked from various substrates or from a flight interception trap made of tulle fabric (~2,5m x 10m) held between two wood piles or set up in a suburban backyard.

Plant family, generic and specific names follow the classification used in Database of Vascular Plants of Canada (VASCAN) (http://data.canadensys.net/vascan/search).

Note.

Bousquet et al. (2013) recorded this species from Quebec without any further comment, possibly on the basis of a vague record (“Quebec to Georgia west to Indiana and Texas”) by Valentine (1998). This small species is strongly saltatorial and can be difficult to catch in hot weather. We provide, for the first time, data on the occurrence of this species in the province.

Species identification confirmed by RSA, 2016

This native species is easily separated from all other known to occur in Quebec by the conspicuous elongate postscutellar spot of white vestiture and spot of dense white scales at the base of elytral interstriae 2 and 3. Nothing is known of its habits or life history, except that adults were collected in August on dock, L. spp., including golden dock, L. () (Bright 1993). Ontario was until now considered as the eastward limit of its range in Canada (Bousquet et al. 2013). A photograph of one of the specimens reported herein is posted on bugguide.net (http://bugguide.net/node/view/1077586/bgpage).

This Palaearctic adventive species was recorded for the first time in North America in 1993 based on specimens collected in Nova Scotia in 1990 (Peschken 1993 and Sampson and MacSween 1993, in Majka et al. 2007b). In Canada, it was subsequently released and is established as a biological control agent against scentless chamomile, (L.) Sch.Bip. (= Mérat) () in British Columbia, Alberta, Saskatchewan, and Manitoba (McClay and De Clerck-Floate 1999). It was also collected on stinking chamomile, L. (), in Nova Scotia (Majka et al. 2007b).

Widely distributed through most of the Palaearctic region (Alonso-Zarazaga 2011), this adventive species was recorded for the first time in North America in PageBreak1994, in Pennsylvania (Hoebeke et al. 2000). Until now, it was known to occur in Canada only in the Maritime Provinces (Bousquet et al. 2013). It is considered a pest of clovers, L. spp. (). It can be distinguished from the superficially similar Kirby, 1808, by its smaller size and the bluish colour of its pronotum and venter (black in ). As indicated by Hoebeke et al. (2000) and by the label data provided hereafter, the flight season extends until late in the year.

Species identification confirmed by RSA, 2016

The occurrence of this small native pale-legged species in the province was expected as it was previously known in Canada from Ontario and the Maritime Provinces. Although this species has been tentatively associated with tick-trefoil, Desv. sp. (), based on the very few available data at the time (Bright 1993), it is worth noting that most of the specimens caught in 2016 were found in association with L. spp. () in wet habitats.

This record comes three years after the first North American detection of the species in Michigan (Anderson et al. 2013) and is based on the incidental finding in the Montreal area (Notre-Dame-de l’Île-Perrot) of a single specimen in 2013 and of dozens of additional specimens 2–3 years later. This widespread Palaearctic species is easily separated from all North American native species by its very small size (<3.5mm), lack of femoral teeth and association with birch, L. spp. All specimens recorded in Quebec were collected in a stand of gray birch, Marshall (), and most were directly beaten from gray birch. Adults are said to be active from May to October in Europe (Hoffmann 1954; as “ Herbst, 1795”), but all specimens reported herein were captured in August (except PageBreakthree specimens caught on September 1, 2016). This species is also newly recorded from Ontario, based on a specimen photographed by Burke Korol in Barrie, Simcoe County, on August 21, 2015 and posted on bugguide.net (http://bugguide.net/node/view/1127147).

This minute native species (1.4–1.6mm) is easily distinguished from all other occurring in Quebec by its extremely wide and convex shape, its tiny size (genus Kissinger, 1957, contains the smallest members of Nearctic ) and its vestiture of sparse but long erect scales. The only other North American congener, (LeConte, 1876), has been recorded as developing in the fruiting bodies of the fungus (Berk.) Samuels, Jaklitsch & Voglmayr () growing on American Beech, Ehrh.

Since its accidental introduction and first detection in the United States in 1879 (Chamberlin, 1933), this Palaearctic species has expanded its range considerably in North America. Surveys conducted from 1997 to 1999 in two Quebec vineyards failed to detect its presence (Bouchard et al. 2005), but its capture by C. Tessier in 2003 indicates that it was already present in the province more than a decade ago. is associated with various L. spp. and spp. (), especially the invasive curled dock, L., also introduced from Europe. Its potential as a biological control agent against this weed was recently assessed (DeGregorio et al. 1992; Piesik 2006).

This native species is associated with L. spp. () (Schoof 1942), specifically common hackberry, L., in Quebec. All specimens collected in Montreal were beaten from common hackberry, and all those from Terrasse-Vaudreuil were attracted to a light source located no more than 10 m from a hackberry tree. Hackberry has been favoured as a street tree and planted in great numbers in some boroughs by the City of Montreal between 1972 and 1984 (QuéBio 2016), obviously PageBreakmuch to the benefit of the weevil. Records provided herein represent a significant northerly extension of the range of this species which was previously only known from as far north as Pennsylvania (O’Brien and Wibmer 1982).

Specimens from southern USA were examined and found to be consistently larger than the northern forms from Quebec and northern USA, but dissections failed to reveal any further significant differences between the two groups. The status of the Canadian and northern USA forms needs further study. For the time being specimens reported herein will be considered as .
