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.
Canada, Ontario, biodiversity, taxonomy, distributional records, Aleocharinae
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
The aleocharine fauna of Ontario was summarized by
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.

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
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.

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.
. 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.
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.
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 (
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.

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 (
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.

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 (

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.
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.
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.
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.
Agaricomorpha websteri is the only known species of the genus in eastern North America. This genus was erected by

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.

Acrotona smithi is newly recorded in Canada based on numerous collections across Ontario. Ontario material was compared with the type series of Acrotona smithi from New York. This species is easily recognized amongst other northeastern Acrotona by the large and fusiform body (Oxypoda-like habitus), the distinctive shape of the aedeagus in lateral view (Figs 117–118), the broadly and shallowly emarginate female tergite VIII (Fig. 123), and, despite some variation, the general shape of the spermatheca (Figs 121–122). Acrotona smithi appears to be a common species inhabiting deciduous to mixed forests and semi-open habitat (e.g. oak savannah) and is probably broadly distributed across northeastern North America.

There are some Canadian specimens currently identified as Acrotona subpygmaea that possess very short elytra and slightly different sexual characters (R. Webster and J. Klimaszewski unpublished data) including one Ontario female [Backus Woods, Wetland trail, 42°39'54"N, 80°29'34"W, sugar maple dom. mesic forest, sift litter, 2.iv.2010]. Therefore, we recommend that identifications of Acrotona subpygmaea be based on the distinctive sexual characteristics of either sex (Figs 125–131) until the Nearctic diversity of this genus is more adequately known. Acrotona subpygmaea is a common species occurring in a variety of forest litter microhabitats and has been collected in both spring and fall. We expect this species to occur broadly across northeastern North America.

Alevonota gracilenta is recorded here for the first time in North America as an adventive species. It is rather easily recognized in North America by the narrow, linear habitus, small eyes and distinctive aedeagus with a long flagellum (Fig. 132).
Alevonota gracilenta apparently prefers a wide range of unforested habitats in its native range but is usually only collected in small numbers and using passive traps (

Atheta alesi is currently only known from Ontario but is expected to occur broadly across eastern North America.
Distribution in Ontario of: 61 Atheta alesi Klimaszewski & Brunke sp. n. 62 Atheta festinans (Erichson) 63 Atheta nescia (Casey) 64 Callicerus obscurus Gravenhorst.
Nearly all specimens were collected from debris in groundhog (Marmota monax (L.)) burrows. Atheta alesi may be another member of the rich insect assemblage associated with groundhog burrows but further collections in this microhabitat are needed to confirm this. Although one specimen was collected in a raised pan trap placed in an agricultural hedgerow, other groundhog-associated staphylinids were collected in this series including Aleochara ocularis Klimaszewski and Bisnius pugetensis (Hatch).
This species is named in honor of Dr. Aleš Smetana, Ottawa, Ontario, Canada, in recognition of his excellent collections from groundhog (Marmota monax (L.)) burrows, which have revealed many interesting species that may be restricted to this microhabitat (e.g. species in
This species is tentatively assigned to the subgenus Microdota based on the following combination of characters present in other Canadian species: small body size, antennomeres 6–10 subquadrate to moderately transverse, Y-shaped ligula, simply formed median lobe of the aedeagus and overall shape of the spermatheca. Atheta (Microdota) alesi is most similar externally and in sexual characters to the type species of Microdota, Atheta (Microdota) amicula (Stephens), which has become introduced into North America. The new species can be separated from Atheta amicula by the longer apical antennomeres (strongly transverse in Atheta amicula), the straight ventral surface of the tubus in lateral view, the differently shaped sclerites of the internal sac in lateral view and the narrower capsule of the spermatheca. The sexual characters of Atheta amicula are illustrated in

Callicerus rigidicornis is recorded from North America as an adventive species for the first time based on Ontario specimens collected in agricultural hedgerows. Males of this species do not have their antennomere 10 conspicuously elongate as in Callicerus obscurus.

Male. Tergite VIII truncate apically with two lateral teeth and two median protuberances (Fig. 147); sternite VIII with apex arcuate but slightly pointed medially (Fig. 148); median lobe of aedeagus in lateral view with moderately large bulbus and short tubus with angulate apex, ventral side of tubus weakly arcuate; internal sac in lateral view with a narrow, elongate and recurved sclerite (Fig. 146).
Female. Unknown.
At present, Dinaraea backusensis is known only from southern Ontario but should occur across eastern North America, at least as far north as southern Canada.
The holotype was collected in a sugar maple dominated forest with a rich diversity of other deciduous trees by sifting deep pockets of leaf litter beside large, old logs. Other native species of Dinaraea have been associated with subcortical habitats (
This species is named after Backus Woods, a 704-acre, old growth, Carolinian forest in Ontario, Canada where the holotypewas collected. We would like to recognize the conservation efforts of the Nature Conservancy of Canada in this region and their recent work in acquiring this property for permanent protection.
Using previous literature, Dinaraea backusensis can be distinguished from all known Nearctic species of the genus except Dinaraea borealis Lohse and Dinaraea planaris (Mäklin) by the distinctive shape of the median lobe in lateral view (see figures in

Strigota obscurata is readily separated from the other Strigota species by the combination of: median lobe constricted basally in parameral view (Fig. 150), male and female tergite VIII with apical margin sharply produced (Fig. 152), the dark coloration, including the legs, the body size (2.2–2.5mm) and elytra at suture distinctly shorter than the pronotum at midline (Fig. 75).
Body narrowly elongate, dark brown to black, with legs and/or tarsi brown, central disc of elytra sometimes with traces of reddish tinge, length 2.2–2.5 mm, moderately glossy, with dense, meshed microsculpture, pubescence short, dense and appearing somewhat silky; head convex, rounded posteriorly, postocular area at least slightly longer than the length of eye, pubescence directed towards midline of disc; antennae stout, antennomeres 1–3 strongly elongate, 4–5 subquadrate and 6–10 moderately transverse; pronotum slightly transverse, widest in basal third, pubescence directed obliquely posteriad, posteriad at midline; elytra transverse, at suture shorter than pronotum at midline, pubescence directed straight posteriad; abdomen subparallel with tergites II–IV deeply impressed basally; metatarsus with basal article as long as two following articles combined.
Male. Tergite VIII with bisinuate base and acutely produced apex, (Fig. 152); sternite VIII elongate with broad distance between base and antecostal suture, apex truncate (Fig. 153); median lobe of aedeagus in lateral view with moderately sized bulbus, tubus of median lobe slightly produced ventrad, internal sac in lateral view with several short, inconspicuous sclerites (Fig. 151); median lobe of aedeagus in ventral (parameral) view with tubus constricted basally (Fig. 150).
Female. Tergite and sternite VIII similar to those of male; spermatheca with club-shaped capsule bearing a small invagination, stem sinuate and coiled apically (Fig. 154). The spermatheca of this species is nearly identical to that of Strigota ambigua except for the capsule, which is more sharply deflexed and of a different shape (Fig. 154, compare with illustrations in
Presently, Strigota obscurata is known only from Ontario but it is expected to occur widely in northeastern North America.
Strigota obscurata occurs in many of the same habitats as Strigota ambigua and was the most commonly collected rove beetle in southern Ontario soybean fields, frequently co-occurring with the latter species (Brunke et al. in prep.).
The specific name is the Latin word for ‘darkened’. This is in reference to the distinct, overall darker body colorationcompared to Strigota ambigua, the only other eastern species of the genus.
Prior to this publication there were five valid species of Strigota in North America: Strigota ambigua (Erichson) with numerous synonyms (see
The type series of Strigota seducens contains 6 specimens with the following data: Cal; ‘seducens-6’, Paratype USNM 39047; Casey bequest 1925; Gusarov lect. des. 2003 [unpublished designation]; our lectotype label, present designation, [1 male, dissected, with genitalia scarcely visible] (NMNH). Same data except: ‘seducens-2’; Gusarov paralect. des. 2003 [unpublished designation]; our paralectotype label, present designation, [1 female, dissected, spermatheca not located] (NMNH). Same data as first paralectotype except: ‘seducens-3’; [1 male, dissected, aedeagus not located] (NMNH). Same except: ‘seducens-4’; [1 female, dissected, with spermatheca] (NMNH). Same except: ‘seducens-5’; [1 sex?, not dissected]. Same except: ‘seducens-Type 39047’; seducens; [1 sex?, damaged, abdomen missing].
For the purpose of nomenclatural stability, we here designate the first mentioned specimen as a lectotype and the other 5 as paralectotypes. The spermatheca of one of the paralectotypes was compared to our specimens of Strigota obscurata and no important differences could be found; the only available aedeagus of Strigota seducens was barely visible in the permanent mount and could not be compared in detail. However, Strigota obscurata may be differentiated from Strigota seducens by the combination of characters in the diagnosis and the uniformly colored elytra (light brown in centre of the disc in Strigota seducens). The only other eastern species of the genus, Strigota ambigua, is easily separated from Strigota obscurata by the larger size (2.4–3.0mm), less produced tergite 8 in both sexes, differently shaped aedeagus and spermatheca (Figs 150–151, 154 vs. illustrations in

Trichiusa compacta appears to be forest inhabiting and was collected from a variety of passive traps and by sifting litter near vernal and semi-permanent forest pools.

This species is currently recognizable only by the combination of habitus (Fig. 77) and the following sexual characters: median lobe of aedeagus in lateral view with tubus narrowed toward apex and sharply pointed apically (not rounded) (Figs 158–159); spermatheca with large, spherical and basally narrowed capsule bearing a small apical invagination, stem relatively straight, looped and twisted posteriad (Fig. 160).
Unlike Trichiusa robustula, Trichiusa hirsuta was collected from upland forested or semi-forested habitats on sandy soil. More collections will help elucidate the habitat requirements of this species.

Distribution in Ontario of: 77 Trichiusa hirsuta Casey 78 Trichiusa robustula (Casey) 79 Zyras planifer (Casey).
This species is currently recognizable only by the combination of habitus (Fig. 78) and the following sexual characteristics: median lobe of aedeagus in lateral view with tubus relatively broad, evenly subparallel and rounded apically (not sharp at apex) (Fig. 162); spermatheca with tubular capsule bearing large and deep apical invagination, stem sinuate, looped and twisted posteriad (Figs 163–164).
This species has been collected from the shoreline of the Great Lakes or from debris nearby. Further collecting is needed to determine whether or not Trichiusa robustula is typical of lakeshore habitat.

This project is part of a recent effort to document the Canadian biodiversity of the large staphylinid subfamily Aleocharinae. Prior investigations have involved the faunas of Vancouver Island (BC) (
Although the specimens studied over the course of this project were from a variety of localities and survey projects, 62% of new distributional records were derived wholly or in part form material generated from a one-year Ontario arthropod survey, a partnership between the University of Guelph Insect Collection, Nature Conservancy of Canada and Ontario Ministry of Natural Resources. We feel that the results of the present study demonstrate that species-level inventories can contribute data that significantly enrich our knowledge of Canadian biodiversity, both adventive and native. In the United States, all-taxa biological inventory projects such as the Great Smokey Mountains ATBI and the Boston Harbor Islands ATBI are making similar contributions to our knowledge of arthropod biodiversity (examples for Coleoptera: Park, Carlton et al. 2010;
Considering the high return of discoveries made during the present study from a relatively small amount of material, it is clear that the checklist of Ontario Aleocharinae provided here represents only a preliminary but important baseline. Undoubtedly, more new species await description and several adventive species known elsewhere in eastern Canada have not yet been recorded from Ontario. We hope that this new baseline will act as a useful intermediate step towards the documentation of Canada’s arthropod biodiversity.
Funding for the Ontario Arthropod Surveys (2010, 20111) was provided by the Nature Conservancy of Canada (NCC) and the Ontario Ministry of Natural Resources (OMNR). JK thanks Natural Resources Canada for their support of this project. The samples from Ontario soybean fields were collected over the course of the Masters thesis of AJB and supported by funding from the Grain Farmers of Ontario, an OMAFRA-University of Guelph Sustainable Production Systems research grant awarded to Rebecca Hallett (University of Guelph, Guelph, Ontario, Canada) and an NSERC PGS-M and rare charitable research scholarship awarded to AJB. We thank the following for assistance with and permission to conduct sampling on their properties: NCC, OMNR, Ontario Parks, rare charitable research reserve, University of Guelph Arboretum, and A.K. Dewdney (Newport Forest, Wardsville, Ontario, Canada). We thank everyone who provided field assistance for the survey projects especially: Cody Anderson, Lauren DesMarteaux, David Makynen, Adam Jewiss-Gaines and Robert Pivar. We are grateful to the following people who provided access to specimens under their care: A. Davies (CNC), A. Newton and M. Thayer (FMNH), M. Sörensson (MZLU), D. Furth and F. Shockley (NMNH), R. Webster (cRW) and J. Frisch (ZMB). We thank one anonymous reviewer and A. Davies for corrections and correspondence that greatly improved the manuscript. Additionally, A. Davies graciously provided published and unpublished distribution data from his database. We are grateful to M. Thayer for producing the habitus image of Stethusa klimschi. V. Gusarov (University of Oslo, Norway) kindly provided information regarding the online North American record of Callicerus obscurus and other helpful correspondence.
