Abstract
A comprehensive species review of the genera Gyrophaena Mannerheim and Eumicrota Casey is presented for New Brunswick, Canada. Twenty-four species of Gyrophaena are reported from New Brunswick including two new species, and two species of Eumicrota. Nineteen previously described species are newly recorded in New Brunswick, eight of which are newly reported in Canada. New species are: Gyrophaena meduxnekeagensis Klimaszewski & Webster, sp. n., and G. pseudocriddlei Klimaszewski & Webster, sp. n. New Canadian records are: G. chippewa Seevers, G. corruscula Erichson, G. dybasi Seevers, G. fuscicollis Casey, G. illiana Seevers, G. involuta Casey, G. laetula Casey, and G. lobata Casey. New records for New Brunswick: G. fuscicollis Casey, G. caseyi Seevers, G. chippewa Seevers, E. corruscula Erichson, G. criddlei Casey, G. dybasi Seevers, G. flavicornis Melsheimer, G. gaudens Casey, G. gilvicollis Casey, G. gracilis Seevers, G. illiana Seevers, G. involuta Casey, G. laetula Casey, G. lobata Casey, G. sculptipennis Casey, E. socia (Erichson), G. subnitens Casey, G. uteana Casey, and G. vitrina Casey. All species are documented by colour habitus images, black/white images of genital structures, and distributional maps. All female genital structures are presented

Introduction
Ashe (2001) recorded 62 valid species of Gyrophaena from America north of Mexico. The genus is very poorly known in Canada and the only key to identification of species was provided by Seevers (1951) in his North American revision published over half a century ago. This outstanding contribution requires updating, particularly at the specific level, for the Canadian fauna. Moore and Legner (1975) recorded 13 species from Canada and none from New Brunswick. Campbell and Davies (1991) listed 20 species of Gyrophaena and one of Eumicrota for Canada, and 5 species of the former genus for the province of New Brunswick. Ashe (1984) published a thorough generic revision of the subtribe Gyrophaenina with a review of described subgenera but it lacked species level treatment. Here we present the first comprehensive species review of the genera Gyrophaena and Eu- microta from New Brunswick, Canada. We report 26 species including two new species, 8 new national and 19 new provincial records. There are now 29 species of Gyrophaena and two species of Eumicrota known to occur in Canada, considering new data provided in this contribution, and records provided by Campbell and Davies (1991) and Dollin et al. (2008). Intensive collecting of aleocharine rove beetles in New Brunswick since 2004 by the second author (RPW) has yielded many new species, and new provincial and national records. These records will be published in a series of papers. ‘The goal of the present contribution is to describe two new species, publish new collection and bionomic data on Gyrophaena, and to provide a revised key for the identification of species.
Method and conventions
Collection method. Various kinds of mushrooms and forest litter were sifted using the method described by Smetana (1971) and other methods described below. Specimens of Gyrophaena are easily collected from various kinds of mushrooms by breaking the mushrooms into pieces in a plastic box and then collecting the beetles as they move. This was the primary method employed for collecting most of the specimens reported in this study.
Specimen preparation. More than 300 adult specimens of Gyrophaena were ex- amined and most specimens were dissected. The genital structures were dehydrated in absolute alcohol and mounted in Canada balsam on celluloid microslides and pinned with the specimens from which they originated. The photographs were taken using an image processing system (Nikon SMZ 1500 stereoscopic microscope; Nikon Digital Camera DXM 1200F; and Adobe Photoshop software).
Terminology mainly follows that used by Seevers (1951) and Ashe (1984). The ventral part of the median lobe of the aedeagus is considered to be the part of the bul-

bus 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 part.
Distribution. Distribution maps, created using ArcMap and ArcGIS, are present- ed for each species recorded in New Brunswick. Distribution of each species in Canada and Alaska is noted. New provincial records are indicated in bold. The following col- lection abbreviations are employed in the text:

Results
Twenty-six species of Gyrophaena are now known to occur in New Brunswick (see the checklist) bringing the total number of all aleocharine species known from the province to 175 (Klimaszewski et al. 2009; Webster et al. 2009). Two of these species, Gyrophaena meduxnekeagensis Klimaszewski & Webster, sp. n., and G. pseudocriddlei Klimaszewski & Webster, sp. n., are described as new to science, 19 species are newly recorded for New Brunswick, and 8 are newly recorded for Canada. One species, G. meduxnekeagensis, is added to the Quebec staphylinid fauna. Collection and bionomic data for all species are presented in the bionomics section of each species account and in Appendix 1.

Description. Body small, length 1.2-3.5 mm, broadly oval and dorso-ventrally flattened (Figs 1-30); coloration flavate, brown, piceous, or black, usually bicoloured but sometimes uniformly coloured; integument of forebody with approximately uni- formly distributed microsetae and enlarged macrosetae in large insertion pores, often elevated (asperities), forming distinct patterns on pronotum and head; isodiametric meshed microsculpture usually present; head with well-developed temporal region; in- fraorbital carinae present; eyes large and often prominent, finely faceted and broadly separated; labrum broadly oval or trapezoidal with sensory setae forming patterns (Ashe 1984); mandibles robust, the right mandible bearing one, usually well-developed inter- nal tooth, and a well-developed internal membranous lobe (the prostheca), which bears rows of small dents or teeth (Ashe 1984); maxilla: lacinia obliquely truncate and with numerous closely spaced teeth (spore brush), and rows of setae on the outer lobe, galea provide a cup-like cap over the apex of the lacinial comb, which probably helps retain food scraps from mushrooms (Ashe 1984); ligula short, entire, produced and broadly rounded at apex; antennae with 4" article small, 5" slightly broader than 6", 4-10 usu- ally incrassate (Figs 1-30); pronotum usually transverse with hypomera visible from the side; mesocoxae broadly separated (Fig. 2); elytra usually broad-shouldered (Figs 1-30); abdomen tapering apically; mesosternal process truncate apically and at least as long as metasternal one; spermatheca sclerotized, with a lateral plate-like flange on the short stem, capsule spherical (Figs 36, 43, 50, 61, 68, 75, 82, 93, 104, 115, 122, 129, 136, 149, 156, 163, 170, 177, 189, 196, 203); median lobe of aedeagus variably shaped, often tubular or trough-shaped and with either ventral projections of various shapes and sizes forming a complex structure (Figs 89, 96, 100, 107, 111, 118, 125, 132, 139), or without the aforementioned (Figs 32, 39, 46, 53, 57, 64, 71, 78, 85, 139, 145, 152, 159, 166, 173, 180, 184, 192, 199); apical portion of internal sac rigid and forming elongate projection from where flagellum is normally exerted, the internal sac unlike most other aleocharine genera, lacks internal and external spines and sclerites; paramere with broad apical lobe bearing four setae, usually two longer and two shorter ones (Figs 33, 40, 47, 54, 58, 65, 79, 86, 90, 97, 101, 108, 112, 119, 126, 133, 140, 146, 153, 160, 167, 174, 181, 186, 193, 200); male tergite 8 usually with two rela- tively large lateral teeth and smaller apical teeth in median part of apical margin (Figs 34, 41, 48, 55, 59, 66, 80, 87, 102, 109, 113, 120, 127, 134, 141, 147, 154, 161, 168, 175, 182, 187), rarely larger lateral teeth are reduced and smaller median teeth are lack- ing (Figs 73, 194), or lateral teeth are transformed into large lateral lobes (Figs 91, 98, 102, 109, 120, 127); species strictly associated with mushrooms. ‘The species groups in Gyrophaena are mainly defined based on similarities of the median lobe of the aedeagus.
Bionomics. Adults of Gyrophaena are obligatory inhabitants of fresh mushrooms where they feed, mate, and lay eggs on fruiting bodies, and their larvae must mature before the fruiting body decays (Ashe 1984). Gyrophaena species occur on fleshy and woody polypores, boletes, and fleshy gilled mushrooms, and are very abundant on the latter (Ashe 1984, 2001). We have observed adult Gyrophaena in rotting (early stages of decay) and dried mushrooms but in much smaller numbers than in fresh mushrooms. Mushroom habitats have several unique attributes: they are ephemeral, unpredictable

in time and space, and extremely heterogeneous in physical and chemical characteris- tics (Ashe 1984). Adults of gyrophaenes have developed adaptations to find and live
on desirable mushrooms. ‘The principal structural adaptations of the adults are modi-
86 Jan Klimaszewski, Reginald P Webster & Karine Savard / ZooKeys 22: 81-170 (2009)
fications of their mouthparts. The beetles feed by “grazing” maturing spores, basidia, cystidea, and hyphae from the hymenium layer of fresh mushrooms and their maxillae are highly modified for this purpose (Ashe 1984). The galeal setae form a cap over the apex of the lacinial spore brush for efficient collecting of material removed from the hy- menium. Other adaptations of the gyrophaenes to their ephemeral and unpredictable habitat and food source are a short life cycle and efficiency in locating and colonizing their mushroom hosts (for details, see Ashe 1984). Adults may also be found in moist forest litter and under logs, which may be an adaptation for survival when few suitable mushroom habitats are available (Ashe 1984). Some adults were collected by one of us (RPW) quite early in the season, which would suggest that some species probably overwinter in litter as adults.
Geographic distribution. Sixty-two valid species of Gyrophaena and seven spe- cies of Eumicrota are known from America north of Mexico (Ashe 2001); 31 species, including present records, are known to occur in Canada.
Phylogenetic afhliation. Gyrophaena and allied genera are considered to comprise a subtribe of Gyrophaenina, which is a sister taxon of subtribe Bolitocharina (Ashe 1984). Ashe (1984) recognized three major evolutionary lineages of Gyrophaenina: the “Brachida” lineage, the “Sternotropa” lineage, and the “Gyrophaena” lineage. The “Gy- rophaena lineage includes Gyrophaena, Phanerota and Eumicrota. The “Sternotropa” lineage includes Agaricochara, Brachychara, Agaricomorpha, Adelarthra, Pseudoligota and Sternotropa. The “Brachida” lineage includes Brachida and Probrachida. The “Gy- rophaena lineage is considered to be a sister group of the “Sternotropa” lineage. For
details, see Ashe (1984).

Comments. Our specimens agree in all respects with the description and illustra- tions of this species by Seevers (1951), but tergite 8 of males in our specimens has only 2-4 median small teeth while in Seever’s illustration there are 5 small median teeth. We attribute this difference to intra-specific variation.

Comments. Gyrophaena subnitens is similar externally to G. meduxnekeagensis but may be distinguished from the latter species by paler, light-yellow antennae, short elytra (Fig. 25), and the shape of tubus of median lobe of aedeagus without basal swell- ing (Fig. 166). From Palaearctic G. polita (Gravenhorst) (Figs 27, 180-183), it differs in having a lighter body coloration, shorter and more rapidly converging postocular temples of head, and broader pronotum (Fig. 25). The genital structures are generally similar in these species.

Etymology. In reference to Meduxnekeag in the Meduxnekeag Valley Nature Preserve where the type and most of the paratypes were collected. This private protected area, adjacent to the Meduxnekeag River and established by the Medux- nekeag River Valley Association, is home to an unsually high number of rare plant and Coleoptera species. The word “Meduxnekeag” is a Maliseet Indian one meaning “rough or rocky at its mouth” presumably applied to the mouth of the river itself.

Description. Body length 1.5—2.4 mm, approximately uniformly dark brown, elytra may have some paler irregular small spots, base of abdomen sometimes slightly paler than the rest of abdomen. Punctation: vertex of head with at least six moderately-sized coarse punctures on each side, pronotum with two median rows of coarse punctures and additional punctures scattered elsewhere, elytra with fine, sparse punctures. Microsculpture: reticulate throughout but weaker on prono- tum. Antennae light yellow-brown to brownish (Fig. 26). Pronotum 1.6 times as wide as long. MALE: tergite 8 with two large lateral teeth, and two small median teeth, which are sometimes substantially reduced in size, apical margin slightly emarginate medially (Fig. 175); sternite 8 rounded apically (Fig. 176). Median lobe of aedeagus with long and apically divided tubus (Fig. 173), its base swollen basally and angular in shape (Fig. 173), apical projection of internal sac arcuate (Fig. 173).

Comments. Gyrophaena meduxnekeagensis is similar externally to G. subnitens but may be distinguished from the latter species by its darker, light yellowish- brown to brown antennae, long elytra (Fig. 26), and the shape of the tubus of median lobe of aedeagus with a basal swelling (Fig. 173). It differs from Palaearctic G. polita (Gravenhorst) (Figs 27, 180-183) by lighter body coloration, shorter and more rapidly converging postocular temples of the head, and broader pro- notum (Fig. 26). The genital structures are in general similarly shaped in the two latter species (Figs 173-179, 180-183). Females of G. meduxnekeagensis may be confused with those of G. corruscula from which they differ externally by their infuscated antennae.

Distribution (Map 24). CANADA: New Brunswick; UNITED STATES: Wisconsin.
Comments. Gyrophaena gracilis is externally the most distinctive species of the genus. Unlike other Gyrophaena species it has an extremely elongate postocu- lar temple area of the head with sides subparallel for most of its length (Fig. 1), a small, evenly punctate pronotum (Fig. 1) and a swollen abdomen (Figs 1, 2). Adults of this species occurred within the pores of the host mushrooms. ‘The elon-
