New Coleoptera records from New Brunswick, Canada: Mordellidae and Ripiphoridae

Abstract Eleven species of Mordellidae are newly recorded for New Brunswick, Canada. Six of these, Falsomordellistena discolor (Melsheimer), Falsomordellistena pubescens (Fabricius), Mordellistena ornata (Melsheimer), Mordellaria undulata (Melsheimer), Tomoxia inclusa LeConte, and Yakuhananomia bidentata (Say)are new for the Maritime provinces. Falsomordellistena pubescens is new to Canada. Pelecotoma flavipes Melsheimer (family Ripiphoridae) is reported for the first time for New Brunswick and the Maritime provinces. Collection and habitat data are presented for all these species.


Introduction
This paper treats new Coleoptera records from New Brunswick, Canada, of the families Mordellidae and Ripiphoridae. A general overview of the Mordellidae (tumbling flower beetles) was provided by Jackman and Lu (2002). Adults feed on pollen and are often found on flowers of umbelliferous (Apiaceae) and composite (Asteraceae) species. Larvae feed mainly in living herbaceous stems, decaying wood, and fungi, depending on the species (Jackman and Lu 2002). Ford and Jackman (1996) summarized the known larval host plants of North American species of this family. The North American species were revised by Liljeblad (1945), and Bright (1986) provided a catalog of North American species. Later, Jackman (1991) made additions and corrections to the catalog, and Jackman and Lu (2001) and Lisberg (2003) made additional taxonomic changes to North American species. McNamara (1991) reported 14 mordellid species and subspecies for New Brunswick. Majka and Jackman (2006), in a review of the Mordellidae of the Maritime provinces (New Brunswick, Nova Scotia, Prince Edward Island), reported another six species for New Brunswick and removed Mordella atrata lecontei Csiki, bringing the total number of known species to 19. Here, we add 11 species to the faunal list of the province. Falin (2002) provided a general review of the Ripiphoridae (the ripiphorid beetles) of North America, including an overview of the biology and life history of various members of this family. Members of this family are unusual among Coleoptera in that they are endoparasitoids on insects such as aculeate Hymenoptera, Coleoptera (Anobiidae, Cerambycidae), and Orthoptera (Blattidae) (Falin 2002). Species occurring in the Maritime provinces are parasitoids of insects such as aculeate Hymenoptera (Apidae, Halictidae) (Ripiphorus sp.) and beetles in the genus Ptilinus (Pelecotoma) (Linsley et al. 1952;Svácha 1994;Falin 2002). Campbell (1991) reported 10 species of Ripiphoridae from Canada but none from the Maritime provinces.    . To date, no specimen has been found to support this record and this record is considered questionable. Here, we report another species of Ripiphoridae for New Brunswick and the Maritime provinces.

Methods and conventions
The following records are based on specimens collected during a general survey by the first author to document the Coleoptera fauna of New Brunswick and from by-catch samples obtained during a study to develop a general attractant for the detection of invasive species of Cerambycidae. Additional records were obtained from specimens contained in the collection belonging to Natural Resources Canada, Canadian Forest Service -Atlantic Forestry Centre, Fredericton, New Brunswick.

Collection methods
Many specimens of Mordellidae were collected by sweeping vegetation or flowers. Others were collected from Lindgren 12-funnel trap samples during a study to develop a general attractant for the detection of invasive species of Cerambycidae. These traps visually mimic tree trunks and are often effective for sampling species of Coleoptera that live in microhabitats associated with standing trees (Lindgren 1983). See Webster et al. (in press) for details of the methods used for trap deployment and sample collection. 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.

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:

Species accounts
All records below are species newly recorded for New Brunswick, Canada. Species followed by ** are newly recorded from the Maritime provinces of Canada. The classification of the Mordellidae and Ripiphoridae follows Bouchard et al. (2011). Majka and Jackman (2006) newly reported six species of Mordellidae for the province of New Brunswick and removed Mordella atrata lecontei Csiki, bringing the total number of known species to 19. Eleven more species are reported here (Table 1)  Collection and habitat data. The adults in New Brunswick were captured in Lindgren funnel traps deployed in the forest canopy in a red oak (Quercus rubra L.) forest. Adults were collected during July and August. This species has been beaten from dead limbs of various species of hardwoods in Indiana (Downie and Arnett 1996).

Family Mordellidae Latreille, 1802
Distribution in Canada and Alaska. ON, NB (McNamara 1991). Collection and habitat data. Tomoxia inclusa was found in an old red oak forest, a mixed forest, and a mature red spruce (Picea rubens Sarg.) forest. Adults were collected from flowers of meadowsweet (Spiraea alba Du Roi), on a recently cut spruce (Picea sp.) log, and in Lindgren funnel traps. This species was collected during July in New Brunswick. This species has been reared from Tilia sp. (Brimley 1951 Collection and habitat data. In New Brunswick, adults of this large species were captured during July and August in Lindgren funnel traps in the forest canopy in a silver maple (Acer saccharinum L.) swamp. Downie and Arnett (1996)  Collection and habitat data. A large series of this species was captured in Lindgren funnel traps deployed in the forest canopy of an old red oak forest. One individual was found on foliage in a regenerating (20-year-old) mixed forest. Adults were captured during July and August. In Wisconsin, this species was captured in flight intercept traps and malaise traps in sandy oak barrens and a mixed southern forest (Lisberg and Young 2003 Collection and habitat data. A large series of this species was collected from flowers of winter berry (Ilex verticiliata (L.) Gray) in a red maple (Acer rubrum L.) and alder (Alnus sp.) swamp. Adults were captured during early July. In Wisconsin, this species was captured in malaise traps on the margin of a southern mixed deciduous hardwood forest (Lisberg and Young 2003). Downie and Arnett (1996)  Collection and habitat data. One individual of this species was captured during July in a Lindgren funnel trap in a mature hardwood forest with sugar maple (Acer saccharum Marsh.), American beech (Fagus grandifolia Ehrh.), and white ash (Fraxinus americana L.). Elsewhere, Lisberg and Young (2003) collected one specimen of this species from Queen Anne's lace (Daucus carota L.) and others from flight intercept and malaise traps in an oak barrens adjacent to a sand barrens and field. Downie and Arnett (1996)  Collection and habitat data. One individual of this species was swept from foliage in a brushy opening of a regenerating (20-year-old) mixed forest during late June. This species was reared from Gleditsia triacanthos L. (Fabaceae) (larvae feed inside the thorns) in Tennessee, USA (Ford and Jackman 1996), but undoubtedly uses other hosts in New Brunswick as this host species does not occur in the province.

Tomoxia inclusa
Distribution in Canada and Alaska. ON, NB, NS (McNamara 1991;Majka and Jackman 2006). Mordellina ancilla was newly recorded from Nova Scotia and the Maritime provinces by Majka and Jackman (2006). Collection and habitat data. In New Brunswick, M. pustulata adults were swept from foliage along a river margin, in a regenerating (20-year-old) mixed forest, and along a power-line right-of-way through a mixed forest. Adults were also swept from flowers of bristly sarsaparilla (Aralia hispida Vent.) in a small old field within a regenerating (20-year-old) mixed forest. This species was collected during late June and July. Elsewhere, M. pustulata has been reared from stems of Gentiana andrewsii Griseb.
Distribution in Canada and Alaska. BC, AB, SK, MB, ON, QC, NB, NS (Mc-Namara 1991; Majka and Jackman 2006). This species was newly recorded from Nova Scotia and the Maritime provinces by Majka and Jackman (2006). Collection and habitat data. In Wisconsin, adults of M. fuscipennis were collected at a black light and from flight intercept and malaise traps in various hardwood forests (Lisberg and Young 2003). In Nova Scotia, adults were collected from deciduous and mixed coniferous forests (Majka and Jackman (2006). This species was also found in various deciduous and conifer forest types in New Brunswick. Adults were captured in Lindgren funnel traps in a mature hardwood forest with sugar maple, American beech, and white ash, an old red oak forest, an old-growth northern hardwood forest with sugar maple and yellow birch (Betula alleghaniensis Britt.), in old and mature mixed forests, in an old red pine (Pinus resinosa Ait.) forest, in a mature red spruce forest, and in an old-growth white spruce (Picea glauca (Moench) and balsam fir (Abies balsamea (L.) Mill.) forest. The only adult with specific micro-habitat data was collected from goldenrod (Solidago sp.) flowers. Two individuals were collected at an ultraviolet light near a mixed forest. Adults were collected during July and August.
Distribution in Canada and Alaska. ON, QC, NB, PE, NS, (McNamara 1991;Majka and Jackman 2006). Collection and habitat data. In Wisconsin, M. ornata was collected from sumac (Rhus sp.), poplar (Populus sp.), Ceanothus sp., and flowers of two Cornus species (Lisberg and Young 2003). Adults were also captured in flight intercept and malaise traps in oak forests, and in southern and northern hardwood forests. In New Brunswick, this species was swept from foliage along a river margin and captured in a Lindgren funnel trap deployed in an old silver maple swamp. Adults were captured during June and July.  Majka and Jackman 2006). Majka and Jackman (2006) reported this species as newly recorded for New Brunswick, Nova Scotia, and Prince Edward Island in Table 1 of their list of species of the Maritime provinces but inadvertently included no supporting data for the New Brunswick record. Here, we include this record and additional records that establish the presence of this species for New Brunswick.
Family Rhipiphoridae Gemminger, 1870  reported Ripiphorus fasciatus (Say) and the family Rhipiphoridae for the first time for New Brunswick, Nova Scotia, and the Maritime provinces. Here, we report another species of Ripiphoridae, Pelecotoma flavipes Melsheimer, for the first time for New Brunswick and the Maritime provinces (Table 1).

Subfamily Pelecotominae Seidlitz, 1875
Pelecotoma flavipes Melsheimer, 1846** http://species-id.net/wiki/Pelecotoma_flavipes Map 12 Collection and habitat data. A large series of this species was captured in Lindgren funnel traps in an old red oak forest. Most individuals were captured in traps in the forest canopy. One individual was captured in a Lindgren funnel trap in the canopy of a red pine in an old red pine forest; another emerged from barn timbers. Adults were captured during July. This species is a parasitoid of Ptilinus ruficornis (Say) (Anobiidae) and is found on exposed dead wood of sugar maples, American beech, and oak (Stephens 1968;Acciavatti and Simone 1976) and probably has a life history similar to that of Pelecotoma fennica (Svácha 1994). Ptilinus ruficornis was common at both localities where P. flavipes was collected.
