Introduction

This paper treats the families Chrysomelidae and Megalopodidae. The Megalopodidae (megalopodid leaf beetles), historically considered a subfamily of Chrysomelidae (Seeno and Wilcox 1982), is a small family of leaf-feeding beetles related to the ChrysomelidaePageBreak. Only the genus occurs in North America. Known hosts of North American species include and spp. Larvae are leaf miners and adults feed externally on leaves (Clark and Riley 2002). Seven species (as subfamily Zeugophorinae in the Chrysomelidae) were reported from Canada by LeSage (1991). No species were reported from this family from New Brunswick or the Maritime provinces (New Brunswick, Nova Scotia, Prince Edward Island).

The Chrysomelidae (the leaf beetles) is one of the largest families of beetles. The Chrysomelidae, as the common name implies, are phytophagous and feed on leaves of plants, usually Angiospermae. Adults of most species are either monophagous or oligophagous and usually use terrestrial species, whereas the larvae have more diverse feeding habits. Donaciinae larvae are aquatic and live on submerged stems and roots of their host (Hoffman 1940). Case-bearing larvae are found in three subfamilies in Canada: larvae of the Clytrinae feed on debris in ant nests (LeSage and Stiefel 1996), larvae of the Cryptocephalinae feed on decaying leaves in litter (LeSage 1985, 1986a), and larvae of the Chlamisiinae eat fresh leaves in the open like the adults (LeSage 1982). Root miners are mainly found in Alticini, Eumolpinae, and Galerucini, whereas leaf miners are numerous in Alticini and in all Hispini (Lawson 1991). Riley et al. (2002) presented a general review of the Chrysomelidae of North America, and that publication should be consulted for details on the classification and a general overview of the biology of members of this family.

Riley et al. (2003) reported 139 species of Chrysomelidae from New Brunswick, Canada in their catalog of the leaf beetles of North America. Since that publication, the adventive (Linnaeus) and (Paykull) have been newly reported from the province by Finnamore (1988) and Weston and Hoebeke (2003), respectively. Majka and LeSage (2007) reported on the overall distribution of in Maritime provinces, and LeSage et al. (2007) on that of . The following year, Majka and LeSage (2008a) reported the presence of (Linnaeus) in Nova Scotia and Quebec, but did not report it from New Brunswick, although it will likely be found in the province with additional sampling. Majka and LeSage (2008b) and Majka and Kirby (2011) reported on the distribution and range expansion of the adventive (Scopoli) in the Maritime provinces, including New Brunswick. LeSage et al. (2008) confirmed the presence of both introduced asparagus leaf beetles ( (Linnaeus), (Linnaeus)) in the Maritimes, including New Brunswick. Majka and LeSage (2008c) confirmed the presence of the introduced Müller in New Brunswick, and the following year LeSage and Majka (2009) confirmed the presence of the introduced Linnaeus. Most recently, Majka and LeSage (2010) reported White and LeConte from New Brunswick in their review of the of the Maritime provinces, increasing the number of species of Chrysomelidae known from New Brunswick to 143.

A few comments are required regarding Parry, Parry, and (Suffrian) which were recorded from New Brunswick by LeSage (1991)PageBreak but not listed by Riley et al. (2003) in their catalog. There are no specimens of and in the CNC (Canadian National Collection of Insects, Arachnids, and Nematodes) and these two species were not reported from New Brunswick by Riley et al. (2003), and thus these species are excluded from the provincial list, although it is probable that both species occur in the province. There are many specimens in the CNC under the name but their determinations have not been verified and may be a synonym of (Fabricius). The genus is in need of revision. This species is therefore excluded from the provincial list until this genus is revised and the species name of the specimens in the CNC can be verified.

Intensive collecting by the first author and others since 2003 has resulted in the discovery of additional species of Chrysomelidae from New Brunswick (Table 1). Additional records were discovered in the older material preserved in the Canadian National Collection in Ottawa, including the first record of the family Megalopodidae. The purpose of this paper is to report on these new discoveries.

Methods and conventions

The following records are based in part on specimens collected as part of a general survey by the first author to document the Coleoptera fauna of New Brunswick. A description of the habitat was recorded for all specimens collected during this survey. Locality and habitat data are presented exactly as on labels for each record. This information, as well as additional collecting notes, is summarized and discussed in the collection and habitat data section for each species.

Collection methods

Most specimens were collected by sweeping vegetation in various habitats, and beating, sweeping, or hand picking beetles from host plants. Additional records were obtained from specimens contained in the collection belonging to Natural Resources Canada, Canadian Forest Service - Atlantic Forestry Centre, Fredericton, New Brunswick and the Canadian National collection, Ottawa, Ontario.

Specimen preparation

Males and females of some species were dissected to confirm their identity. Male aedeagi were dissected in 70% ethanol and glued on tip of small points under the specimens from which they originated. The female genital structures were dissected in 70% ethanol, dehydrated in absolute alcohol, transferred into cedar oil, and mounted in Canada balsam on small transparent acetate cards pinned with the specimens from which they originated.

Distribution

Distribution maps, created using ArcMap and ArcGIS, are presented for each species in New Brunswick. Every species is cited with current distribution in Canada and Alaska, using abbreviations for the state, provinces, and territories. New records for New Brunswick are indicated in bold under Distribution in Canada and Alaska. The following abbreviations are used in the text:

Adults from New Brunswick were collected from the foliage of Lam. (ox-eye-daisy) in open disturbed roadside sites near a red pine ( Ait.) and a jack pine ( Lamb.) forest. Specimens were also collected in the late fall on a paved road during warm afternoons. Adults were collected during June, September, and October.

AK, YT, NB (Riley et al. 2003). The population in New Brunswick is likely an adventive Palaearctic species known from Europe, Siberia, the Far East, and Alaska (Bieńkowski 2001).

Comment.

Brown, 1962 was placed in synonymy with (Linnaeus) by Bieńkowski (2001: 152), a synonymy accepted by Riley et al. (2003) in their catalog. It makes sense for specimens from Alaska or Yukon to belong to the nominal Palaearctic subspecies since this state and province can be considered as the easternmost part of the natural distribution of that extends over the Bering Detroit into the New World. On the other hand, the presence of in New Brunswick is not natural and is undoubtedly the result of a recent introduction into eastern Canada, which is not yet fully documented (LeSage, personal observations). Considering that there are nine Palaearctic subspecies (Bieńkowski 2011), it might be advisable not to use a subspecies name until our eastern population can be properly assigned to a subspecies.

BC, AB, MB, ON, NB, NS, PE (Riley et al. 2003). This is a Palaearctic species now widely established throughout much of the northern half of the USA and Canada (Riley et al. 2003). It was introduced, together with (Duftschmid), for the biocontrol of purple loosestrife ( L.) and has been successful in controlling this weed (Hight et al. 1995). Consequently, its presence on alder is incidental and the damage to the leaves may have been done before by the alder flea beetle ( Harris), which is closely associated with this bush (LeSage 1995).
