Abstract

The Aleocharinae (Coleoptera: Staphylinidae) of Ontario were reviewed in the context of recently studied material, primarily from insect surveys conducted by the University of Guelph Insect Collection (Ontario, Canada). Aleochara daviesi Klimaszewski & Brunke sp. n., Agaricomorpha websteri Klimaszewski & Brunke sp. n., Atheta (Microdota) alesi Klimaszewski & Brunke sp. n., Dinaraea backusensis Klimaszewski & Brunke sp. n., and Strigota obscurata Klimaszewski & Brunke sp. n. are described as new to science. We also report 47 new Ontario records and 24 new Canadian records. Callicerus rigidicornis (Erichson) and Alevonota gracilenta (Erichson) are newly reported from North America as adventive species. A checklist, with Canadian distributions by province, of the 224 species of Aleocharinae known from Ontario is given. The following species are placed in subjective synonymy with Dexiogyia angustiventris (Casey): (Dexiogyia asperata (Casey) syn. n., Dexiogyia abscissa (Casey) syn. n., Dexiogyia tenuicauda (Casey) syn. n., Dexiogyia intenta (Casey) syn. n., Dexiogyia alticola (Casey) syn. n.). The following species are placed in subjective synonymy with Acrotona subpygmaea (Bernhauer): (Acrotona avia (Casey) syn. n., Acrotona puritana (Casey) syn. n.). Lectotypes are designated for Thiasophila angustiventris Casey, Thiasophila asperata Casey, Ischnoglossa intenta Casey, Oxypoda rubescans Casey, Chilopora americana Casey, Chilopora fuliginosa Casey, Coprothassa smithi Casey, Atheta subpygmaea Bernhauer, Colpodota puritana Casey, Strigota seducens Casey, Trichiusa compacta Casey, Trichiusa hirsuta Casey and Trichiusa robustula Casey.

Introduction

Over the past ten years, the Aleocharinae (Coleoptera: Staphylinidae) have been one of the most active areas of beetle systematics research in Canada (see references in Gouix and Klimaszewski (2007)), yet knowledge of their true diversity is still rather fragmentary. Focused studies on the aleocharine fauna of the Maritime Provinces of Canada (e.g. Majka and Klimaszewski 2008a; Webster et al. 2009; Majka and Klimaszewski 2010), Newfoundland (Klimaszewski et al. 2011) and Yukon Territory (Klimaszewski et al. 2008a; Klimaszewski et al. 2012) have resulted in the discovery of many new species and have approximately doubled (Maritimes, Yukon) or more than quadrupled (Newfoundland) the known diversity in these areas since the publication of the most recent catalog of Canadian Aleocharinae (Gouix and Klimaszewski 2007).

The aleocharine fauna of Ontario was summarized by Campbell and Davies (1991) (60 species) and updated by Gouix and Klimaszewski (2007) (108 species). Since then, revisions and faunistic studies of Canadian Aleocharinae have raised that total to its current state at 146 species. Recently we have had the opportunity to study new material from Ontario made available through biodiversity surveys by the University of Guelph Insect Collection, and select material deposited in other collections. We herein report the discovery of several new species, the taxonomic or diagnostic clarification of others and new records for Ontario, Canada and North America. Photographs of the habitus, genitalia and other relevant characters are provided to aid in their identification.

Materials and methods

Specimens were examined using Wild Heerbrugg M5A and Nikon SMZ 1000 stereomicroscopes, and nearly all were dissected to examine features of the genitalia. In many cases, tergite and sternite 8 were also examined. These structures were dehydrated in absolute alcohol and mounted in Canada balsam on celluloid microslides and pinned with the specimens from which they originated. Photographs were taken using an image processing system (Nikon SMZ 1500 stereoscopic microscope, Nikon Digital Camera DXM 1200F, and Adobe Photoshop software). Habitus photographs of all included species are provided, while genitalia are illustrated only for those species whose genitalia have not been shown in recent publications. Maps of each species’ distribution in Ontario, Canada were prepared using ARC MAP and Adobe Photoshop. In the species accounts, distributions are given by province or state (Canada, U.S.A.) or by country (elsewhere). These territories are abbreviated using Canada Post and United States Postal Service standards.

Morphological terminology mainly follows that used by Seevers (1978) and Ashe in Newton et al. (2000). The ventral (=parameral) part of the median lobe of the aedeagus is considered to be the part of the bulbus containing the foramen mediale, the entrance of the ductus ejaculatorius, and the adjacent venter of the tubus; the opposite side is referred to as the dorsal (=abparameral) part.

Material was examined from the following collections:

CNC Canadian National Collection of Insects, Ottawa, Ontario, Canada

DEBU University of Guelph Insect Collection, Guelph, Ontario, Canada

FMNH Field Museum of Natural History, Chicago, Illinois, USA

LFC Laurentian Forestry Centre, Quebec, Quebec, Canada

MZLU Museum of Lund University, Lund, Sweden

NMNH National Museum of Natural History, Smithsonian Institution, Washington D.C., USA

ZMB Museum für Naturkunde, Invalidenstrasse 43, 10115, Berlin, Germany

ZMUC Zoological Museum, University of Copenhagen, Copenhagen, Denmark

RWC Reginald Webster Collection, Charters Settlement, New Brunswick, Canada


Additionally, distributions of species included in this account were kindly checked by A. Davies (CNC) against his database of Canadian Staphylinidae to be published in the upcoming second edition of the ‘Checklist of Beetles of Canada and Alaska’ (Davies in Bousquet et al. in prep.). Distributions marked herein with an asterisk (*) represent records based entirely on these data. In the species accounts, the number of specimens for each collection event is given directly preceding the collection abbreviation in brackets. Where appropriate, short discussions pertaining to individual species are given in the species accounts under ‘comments’. We follow the higher taxonomic organization of Ashe in Newton et al. (2000) with changes reflected in Gouix and Klimaszewski (2007) and Paśnik (2010).

Results

As a result of the present study we recognize 224 species of Aleocharinae in Ontario. A checklist by tribe of all known Ontario Aleocharinae species and their distributions in Canada is given in Table 1. Aleochara daviesi Klimaszewski & Brunke sp. n., Agaricomorpha websteri Klimaszewski & Brunke sp. n., Atheta (Microdota) alesi Klimaszewski & Brunke sp. n., Dinaraea backusensis Klimaszewski & Brunke sp.n., and Strigota obscurata Klimaszewski & Brunke sp. n. are described as new to science. Twenty-four species are newly recorded from Canada, 47 species are newly recorded from Ontario, and the Palaearctic species Alevonota gracilenta (Erichson, 1839) and Callicerus rigidicornis (Erichson, 1839) are newly reported as introduced to North America. The genera Agaricomorpha Ashe, 1984, Alevonota Thomson, 1858, Callicerus Gravenhorst, 1802, Dexiogyia Thomson, 1858, Phanerota Casey 1906, Stethusa Casey, 1910 and Thecturota Casey, 1894 are new for the Canadian fauna.

Diagnosis.

Distinguished from other Aleochara by the following combination of characters: antennomere 4 subquadrate and 5–10 slightly transverse (Fig. 2); eyes extremely large, protruding laterally and close to frontal margin, postocular area of head about as large as eye in lateral view, postocular carina strong and complete; pronotum slightly transverse, with basal margin arcuate; elytra slightly longer than pronotum; abdomen subparallel for most of its length; basal metatarsomere slightly longer than the following tarsomere, tarsal claws exceptionally large, narrowly elongate; median lobe of aedeagus with large and narrowly elongate crista apicalis, tubus in lateral view swollen ventrally and sharply produced apically (Fig. 80). Aleochara daviesi is very similar externally to the western North American Aleochara lobata Klimaszewski from which it may be readily distinguished by the shape of the median lobe.

Description

. Body length 4.9 mm; black with legs, elytra (except narrowly at base) and abdominal tergites VII and VIII, rust brown; punctation of forebody coarse, dense and flattened, interspaces between punctures with fine meshed microsculpture (Fig. 2); head broadest apically with very short frons and with strong and complete postocular carina, pubescence of dorsal surface directed toward midline of disc, eyes extremely large, protruding laterally, and close to frontal margin of head, postocular area about as long as eye; antennae with antennomeres 1–3 elongate, antennomere 4 subquadrate and 5–10 slightly transverse; pronotum slightly transverse, shorter than elytra, pubescence directed obliquely posteriad from midline of disc, punctation flattened and forming transversely impressed line at base of disc; elytra with posterior margin nearly straight with slight lateral emargination, pubescence directed lateroposteriad from suture; abdomen subparallel for most of its length, tergites II-IV with deep and V with shallow impression, impressions with dense punctures separated from each other by a distance equal to or less than diameter of a puncture, punctures often touching; basal metatarsomere slightly longer than the following segment; tarsal claws exceptionally large, elongate and with surface smooth.

Male. Tergite 8 bicolored, dark brown/black basally and yellowish apically, truncate apically and with margin slightly crenulate (Fig. 81); sternite eight produced apically (Fig. 82); median lobe of aedeagus in lateral view with large and elongate bulbus produced ventrally at base, crista apicalis narrowly elongate and large, tubus swollen ventrally and sharply produced apically (Fig. 80).

Female: Unknown.

Distribution.

Presently known only from Backus Woods, an old growth deciduous forest in southern Ontario. Aleochara daviesi almost certainly occurs in the eastern United States and elsewhere in southern Canada.

Bionomics.

The holotype was collected by submerging forest litter near the margins of forest pools (some permanent). Other members of the subgenus Echochara are inhabitants of mammal burrows or caves (Klimaszewski 1984). As there are no cave systems at the type locality, we suspect that Aleochara daviesi occurs in the former situation. Although the staphylinids occurring in groundhog (Marmota monax (L.)) burrows have been sampled (Klimaszewski 1984, Smetana 1971, Smetana 1995, this paper) the fauna in burrows/nests of other mammals in eastern North America is essentially unknown. Future survey work in the nests of Nearctic moles, shrews and rodents is warranted.

Etymology.

This species is dedicated to our colleague Anthony Davies (CNC, Ottawa, Ontario, Canada) in recognition of his contribution to the knowledge of Canadian Staphylinidae and in appreciation of his assistance over the years in specimen loans, distributional records and curatorial matters, especially those relevant for this project.

Adventive in Canada.

Comments.

Aleochara tristis was intentionally released in the United States in 1965 to control populations of Face Fly (Musca autumnalis DeGeer), a nuisance pest of and disease vector for livestock, which breeds in their dung (Jones 1967). In terms of biological control, the introduction appears to be a failure as this species is rarely collected and only as singletons. However, it is most certainly established in northeastern North America at low densities (Klimaszewski et al. 2005b, this study).

Distribution in Ontario of: 5 Tinotus trisectus Casey 6 Hoplandria klimaszewskii Génier 7 Hoplandria laevicollis (Notman) 8. Hoplandria laeviventris Casey.

Comments.

This species may be distinguished from all eastern Tinotus but Tinotus caviceps based on the combination of reddish body and elytra with short, bristle-like setae that are directed obliquely laterad (Klimaszewski et al. 2002). The aedeagi and spermathecae of Tinotus trisectus and Tinotus caviceps are extremely similar and there was previously some doubt whether these two species were distinct due to the limited available material of Tinotus trisectus (Klimaszewski et al. 2002). Gusarov (2003a) also followed this concept of the two species, corrected a synonymy and provided additional records for Tinotus trisectus. After examination of Ontario specimens of Tinotus caviceps and Tinotus trisectus we provide further evidence to maintain the status of these species based on the following consistent and unambiguous differences: internal sac of aedeagus of Tinotus caviceps with lower sclerite hooked ventrally in lateral view, not hooked in Tinotus trisectus; in both sexes, antennomere III of Tinotus caviceps strongly flattened and broadened in lateral view, cylindrical in Tinotus trisectus; elytral suture of Tinotus caviceps slightly but distinctly shorter than length of pronotum at midline, approximately the same length or longer in Tinotus trisectus.

Tinotus trisectus appears to prefer open habitats including woodland edges, agricultural fields and oak savannah. Previously, nothing was known about its habitat associations. This species is probably broadly distributed across North America, reaching its northern limit in southern Canada.

Comments.

This is the only eastern species of Platandria (Génier and Klimaszewski 1986) and the first record of this species for Canada. Hanley (2003) reported Platandria from Canada (Ontario) for the first time in a summary of its general distribution but without locality information. Little is known about the biology of Platandria except that they are associated with the flowers of various shrubs (Ashe in Newton et al. 2000), despite an older account of an association with fungi (Blatchley 1910). The above specimens were collected in the flowers of Flowering Dogwood, a species confined in Canada to the Carolinian region of southern Ontario. As far as known, Platandria carolinae is similarly distributed in Canada, possibly indicating a staphylinid-plant association though this species was not among the assemblage of Coleoptera found on Flowering Dogwood by Rhoades et al. (2011) in Tennessee.

Distribution.

Comments.

This species is distinguished from other Nearctic Amarochara based on the extremely dense punctation of the abdominal tergites, weak microsculpture of the forebody and shape of the median lobe of the aedeagus in lateral view.

Amarochara brevios was previously known only from the holotype collected in Kansas via flight intercept trap. Here, we report this species from Ontario, Canada based on numerous specimens collected using pitfall and raised pan traps in soybean fields (only 6 specimens kept as vouchers). While Amarochara inquilina (Casey) and Amarochara formicina Assing are associated with mound-building Formica ants, other species of the genus appear to be general inhabitants of decaying litter and only occasionally inhabit ant nests (Assing 2002). Currently nothing is known about the habitat preferences of other Nearctic Amarochara. Based on recent collections of Amarochara in Canada (Assing 2007, Webster et al. 2009; this study), species of this genus are poorly collected but widespread across eastern North America and all four Nearctic species are now reported from Canada (see below).

Comments.

This species can by distinguished from other Nearctic Amarochara by the following combination of characters: head and pronotum with weak microsculpture; first segment of metatarsus about as long as second to fourth segments combined; punctation of abdominal tergites sparse (Assing 2002, 2007). The shape of the median lobe of the aedeagus is also distinctive in lateral view.

All specimens of this species with collection data were collected in forested reserves using flight intercept traps (Assing 2002, this study) but nothing further is known about its biology.

Comments.

All North American species of Dexiogyia were described by Casey (1894, 1911) (as Thiasophila and Ischnoglossa) and differentiated based on slight differences in body proportions, punctation, pubescence and color. An examination of the relevant types revealed no differences between them in their aedeagi or spermathecae and slight differences in external morphology, which were attributed to intraspecific variation. Therefore, Dexiogyia angustiventris was selected as the valid name for this species based on its appearance before Dexiogyia asperata (Casey) in Casey (1894), and Dexiogyia asperata (Casey) syn. n., Dexiogyia abscissa (Casey) syn. n., Dexiogyia tenuicauda (Casey) syn. n., Dexiogyia intenta (Casey) syn. n.and Dexiogyia alticola (Casey) syn. n.are here placed in synonymy with Dexiogyia angustiventris (Casey). To provide nomenclatural stability we have selected and designated lectotypes for Thiasophila angustiventris Casey, Thiasophila asperata Casey and Ischnoglossa intenta Casey. Additionally, one non-type specimen (Iowa, male) of Dexiogyia angustiventris and five non-type specimens in Casey’s collection (NMNH) of Dexiogyia alticola (California, Siskiou Co., 3 females, 1 male, 1 sex?) were examined.

Seevers (1978) noted that the European species Dexiogyia corticina (Erichson) was probably distinct from Dexiogyia angustiventris based on the longer and shaper teeth on male tergite 8 in the latter species. After examination of dissected specimens of Dexiogyia corticina from Leipzig, Saxonia, Germany (ZMB), we consider both as valid but extremely similar species. Dexiogyia corticina may be distinguished from the Nearctic Dexiogyia angustiventris based on the tubus of the median lobe with a ventral swelling in lateral view (straight in Dexiogyia angustiventris (Fig. 84) and the shorter, obtuse teeth of male tergite 8 (Fig. 85).

Dexiogyia has been associated with subcortical microhabitats, especially those of pine and in the ‘burrows of wood-boring beetles’ (Seevers 1978). This is the first record of the genus from Canada and due to its association with pine (Seevers 1978), we suspect this species to be transcontinental in Canada.

This is the first collection of Oxypoda rubescans since its description based on a male specimen collected in the Catskill Mountains of New York (Casey 1911). The aedeagus of this species is illustrated for the first time (Fig. 90). This species is similar in habitus to Oxypoda hiemalis Casey but is immediately differentiated by the elytra, which are longer than the pronotum at suture. Oxypoda rubescans may be easily recognized by the distinctively shaped median lobe of the aedeagus in lateral view (Fig. 90). To promote nomenclatural stability, we designate a lectotype for this species here.

Comments.

This is the first record of Parocyusa americana since its description based on a female specimen collected from Peekskill, New York (Casey 1906). This species is easily recognized to genus by its habitus and the only other known Nearctic species (Parocyusa fuliginosa (Casey)) is darker, with a slightly shorter and more densely punctate pronotum, and has quadrate to slightly transverse antennomeres 8–10 (see Fig. 28 in Klimaszewski et al. 2011). To promote nomenclatural stability, we designate a lectotype for Parocyusa americana here.

Specimens of Parocyusa americana were found on a stream bank and in a dry streambed under a rock. We expect Parocyusa americana to occur broadly over northeastern North America in habitats near running water.

Comments.

This species was recorded from Canada for the first time by Klimaszewski et al. (2011) based on a specimen collected in Labrador, Newfoundland. The identification of this specimen was based on information provided in Seevers (1978) because the type material could not be located in the NMNH. This material was recently found and we here confirm the identity of the Newfoundland specimen as Parocyusa fuliginosa, newly record it from Ontario and designate a lectotype to promote nomenclatural stability. Parocyusa fuliginosa has been collected in much the same way as Parocyusa americana and we expect both species to occur broadly in eastern North America in habitats near running water.

This is the first record of this species from eastern North America. Gnypeta helenae is indistinguishable externally from Gnypeta canadensis Klimaszewski, which was described based on characters of the male and female genitalia (Klimaszewski et al. 2008b). The authors noted that a wide geographic range of specimens was not available for examination and further study may necessitate re-examination of these species concepts. Study of recent material of both species from the same locality in Haldimand-Norfolk Region, Ontario, Canada confirmed that Gnypeta helenae and Gnypeta canadensis are indeed separate but cryptic species. Specimens of Gnypeta helenae with label data have been collected on the banks of rivers and lakes and from a eutrophic pond edge (Ontario specimen), while those of Gnypeta canadensis were collected in forested wetland habitats and some of these were hand collected from moss on deadwood (Ontario material). Further collecting in wet microhabitats may reveal ecological differences in these two species.

Description.

Body small, compact and oval in outline;length 1.6–1.8 mm; body dark brown with legs, maxillary palpi and 2–3 basal antennomeres yellowish-brown, or body dark brown with pronotum and elytra slightly paler, and appendages and basal part of abdomen yellowish-brown (Fig. 24); forebody with strong meshed microsculpture, punctation coarse, sparse and flatly impressed, pubescence sparse and approximately evenly distributed on forebody; head transverse and produced anteriad, eyes large and longer than postocular area, pubescence directed posteriad and obliquely mediad; ligula narrowly elongate and divided almost to base; antennae slightly incrassate, basal 3 antennomeres elongate, 4 subquadrate, 5–10 increasingly broadening apically, 11 oval and elongate; maxillary palpi with 4 articles, penultimate article expanded apically, and apical article acicular; pronotum strongly transverse, base strongly sinuate, converging apicad, disc with pubescence directed posteriad except for some setae at base directed laterad; elytra at suture distinctly longer than pronotum, pubescence directed straight posteriad; abdomen gradually but weakly tapering apicad, tergites II and III impressed basally, and with elevated punctures.

Male. Tergite VIII transverse, shallowly emarginate medially at the apical margin and with short medio-apical carinate protuberance (Fig. 104); sternite VIII broadly rounded apically (Fig. 105); median lobe of aedeagus in lateral view with large bulbus and U-shaped, narrow tubus with broad and angular swelling subapically; flagellum long, thin, everted and about 3 times as long as tubus (difficult to see in Fig. 103).

Female. Tergite VIII strongly transverse and similar to that of male but lacking median carina; sternite VIII transverse and arcuate apically; spermatheca with spherical capsule and inconspicuous short stem, in general similar to those of Gyrophaena and Eumicrota.

Distribution.

Known from Ontario, Quebec, New Brunswick and Nova Scotia. Agaricomorpha websteri is probably broadly distributed in northeastern North America, south of the boreal forest zone.

Bionomics.

Little is known about the natural history of this species but all specimens were collected in deciduous forests, mostly by passive, above-ground traps indicating high flight capability. Other species of the genus are found on woody and leathery polypore fungi (Ashe in Newton et al. 2000), which commonly grow on dead or dying standing trees. Interestingly, several individuals were captured by Lindgren funnel traps, which typically attract species associated with this type of coarse woody debris.

Etymology.

This species is dedicated to our colleague Reginald P. Webster of Charters Settlement, New Brunswick, who collected the holotype and whose material has contributed much to the knowledge of Canadian biodiversity.

Comments.

Agaricomorpha websteri is the only known species of the genus in eastern North America. This genus was erected by Ashe (1984) to accommodate Agaricomorpha apacheana (Seevers), which occurs in the southwestern United States and is not related to species of the Palaearctic genus Agaricochara Kraatz where it was originally described (Ashe 1984). The genus Agaricomorpha is distinctive among the North American Gyrophaenina for its divided ligula (Ashe in Newton et al. 2000) and strongly transverse pronotum with a distinctly sinuate base. Ashe (1984) listed Agaricomorpha ‘undescr. sp. 3’ as occurring in ‘Canada’ and Agaricomorpha websteri likely represents this taxon.

Comments.

This species has previously been associated with Red Oak (Quercus rubra L.) and some specimens have been collected inside spherical Red Oak galls (Klimaszewski and Majka 2007a). All Ontario specimens were collected in forests containing red oak or in open habitat with several small, Red Oaks. Red Oaks at the Barr property in Northumberland County possessed spherical galls but these were noticed late in the season and did not contain rove beetles when checked. Euvira micmac has also been collected from litter near water and from under sappy Populus bark (Webster et al. 2009, this study), and the association with red oak may be indirect, possibly involving a fungal food source that prefers oak tissue or the microclimate provided by oak galls.

Comments.

This species was erroneously reported from New Brunswick by Klimaszewski et al. (2009) based on misidentified specimens of Gyrophaena nanoides Seevers. Gyrophaena caseyi and Gyrophaena nanoides are very similar externally except that the former has antennomeres 5–10 distinctly transverse (elongate to quadrate in the latter) and antennomere 9 is approximately as long as 10 (longer in Gyrophaena nanoides). For a habitus image of Gyrophaena nanoides see Klimaszewski et al. (2009) (labeled as Gyrophaena caseyi). The median lobe of the aedeagus in lateral view is shaped slightly differently (Fig. 106 versus Fig. 39 in Klimaszewski et al. 2009 (as Gyrophaena caseyi)).

Comments

. The genus Phanerota is newly recorded in Canada based on specimens collected on mushrooms in extreme southern Ontario. This genus may reach its northern distributional limit in southern Ontario, as it was not reported in a recent review of New Brunswick Gyrophaenina (Klimaszewski et al. 2009).

Comments.

This is the first collection of Thecturota pusio since Casey’s description (1894) based on the female holotype from ‘Indiana’ and the first Canadian record of the genus. We have dissected the female holotype for comparison with the Ontario specimens and illustrate the male and female sexual characters for the first time (Figs 109–115). Live specimens of Thecturota pusio were extremely slow-moving and the use of a Berlese funnel likely facilitated the capture of this minute (<2mm) species.
