Further contributions to the aleocharine fauna of the Yukon Territory, Canada (Coleoptera, Staphylinidae).

The aleocharine beetles of the Yukon Territory, Canada are reviewed based on material studied since the most recent survey of the territory in 2008. The present contribution recognizes a fauna of 125 species, of which 9 are new to science, 20 represent new territorial records and one represents a new Canadian record. Seventeen species are considered Holarctic, 6 introduced, and 2 species are of undetermined status (Holarctic or adventive). The Yukon fauna is classified in 32 genera and 8 tribes. The new species are: 1) Acrotona horwoodae Klimaszewski & Godin, sp. n.; 2) Atheta (Microdota) microelytrata Klimaszewski & Godin, sp. n.; 3) Atheta (Microdota) riparia Klimaszewski & Godin, sp. n.; 4) Atheta (Datomicra) whitehorsensis Klimaszewski & Godin, sp. n.; 5) Ocyusa yukonensis Klimaszewski & Godin, sp. n.; 6) Philhygra pseudolarsoniKlimaszewski & Godin, sp. n.; 7) Philhygra terrestris Klimaszewski & Godin, sp. n.; 8) Boreophilia davidgei Klimaszewski & Godin, sp. n.; and 9) Boreophilia herschelensis Klimaszewski & Godin, sp. n.

Introduction

Aleocharinae is the largest subfamily of Staphylinidae and embraces a wide variety of morphologically and ecologically diverse species that are poorly documented in Canada. This subfamily is widely distributed in North America and occurs in almost all terrestrial habitats. Most species are found in forests where they occur in leaf litter, under bark, in fungi, in moss and within the nests of ants, mammals and birds. In forest litter, the aleocharine fauna is a dominant group and part of a complex ecological web that is responsible for nutrient cycling, which ultimately contributes to forest productivity and resilience (Buse and Good 1993, Leschen 1993).

Currently, over 400 species of Aleocharinae in 92 genera are recorded from Canada and Alaska (Gouix and Klimaszewski 2007, Webster et al. 2009, Majka and Klimaszewski 2010, Klimaszewski et al. 2011). In a checklist of Canadian Coleoptera, Campbell and Davies (1991) recorded 59 species of Aleocharinae from the Yukon Territory. Gouix and Klimaszewski (2007) reported a fauna of 65 aleocharine species and in a more focused study of Yukon material, Klimaszewski et al. (2008) described 6 new species and provided 24 new territorial records, raising the total number of species to 95.

The present paper provides an updated review of aleocharine beetles from the Yukon Territory and constitutes important baseline data for monitoring the impact of invasive species, pollution, natural resource extraction and climate change. Additionally, the information and illustrations contained herein will make it possible to incorporate this diverse subfamily into ongoing Canadian biodiversity inventories including those in the Canadian Arctic.

Materials and methods

Over 1,226 adults of Aleocharinae from the Yukon Territory were studied and most specimens were dissected to examine genitalia. The genital structures were dehydrated in absolute alcohol, mounted in Canada balsam on celluloid microslides and pinned with the specimens from which they originated. Photographs of the entire body and the genital structures were taken using an image processing system (Nikon SMZ 1500 stereoscopic microscope; Nikon Digit-like Camera DXM 1200F) and Adobe Photoshop software.

Morphological terminology mainly follows that used by Seevers (1978), Klimaszewski (1984) and Ashe (2001). The ventral 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 ventral part of the tubus of the median lobe with an internal sac and its structures (this part is referred to as the parameral side in some recent publications); the opposite side is referred to as dorsal. In the species descriptions, microsculpture refers to the surface of the upper forebody (head, pronotum and elytra).PageBreak

Samples collected in this study include those from the Ecological Monitoring and Assessment Network (EMAN) plots. Two l ha plots, the Fireweed Drive (mixed pine and willow forest) and Cadet Camp (white spruce mature forest with feathermoss ground cover), have been reserved for long-term monitoring. All samples from these locations were collected from pitfall traps operating from late May to late September. Additional pitfall samples were collected by Donald Reid from early June to early August 2007, and early June to mid August 2008 at an alluvial fan on Hershel Island (dominated by and grasses with some willows). All other sample collections were from organic litter sifting.

Results

In this second recent survey of the Aleocharinae of the Yukon Territory, 125 species in 32 genera and 8 tribes are reported, including two tentative records. Nine species are newly described herein, 20 additional species constitute new territorial records and one species represents a new Canadian record. There are 6 adventive and 17 Holarctic species known from the territory and the status of two other species cannot yet be determined as belonging to either category. Adventive species constitute 4.8% of the total known aleocharine fauna of the Yukon.

Discussion

The present survey increased the known Yukon aleocharine fauna from 95 to 125 species (Klimaszewski et al. 2008) and represents a significant contribution to the documentation of Canada’s entomofauna. Recent baseline surveys of Aleocharinae in other regions of Canada reported 203 species from the Maritime Provinces of Canada, of which 174 have been recorded in the past decade (Majka and Klimaszewski 2010), and 172 species from Newfoundland and Labrador (Klimaszewski et al. 2011).

Intensive sampling of the aleocharine fauna of the Yukon is continuing by the second author and undoubtedly many more species will be discovered in the future. The study of the Yukon fauna is particularly significant for understanding the shift in some species distributions in response to climate warming and for establishing baseline PageBreakbiodiversity data for northern Canada. Additionally, the occurrence of a species in the Yukon Territory otherwise known only from the eastern part of the country provides some evidence for a natural Holarctic distribution. Therefore, a survey of the biodiversity of the Yukon also contributes to our knowledge of species suspected of being adventive.

Paratype

(female). Same data as the holotype (ECW).

This species name is dedicated to Denise Horwood, wife of the second author, who assisted him in numerous aleocharine sample collections.

Body narrowly oval, moderately convex, uniformly black, punctation on forebody fine, dense and not asperate, microsculpture fine but not pronounced; length 2.4 mm; head narrower than pronotum, ratio of maximum width of head to maximum width of pronotum 0.7; antennal articles 7–10 slightly transverse; pronotum moderately transverse, ratio of maximum width to length 1.4, about as wide as elytra; elytra at suture about as long as pronotum; abdomen slightly narrowed posteriad (Fig. 4). MALE: tergite 8 moderately elongate and truncate apically (Fig. 34); sternite 8 widely arcuate apically (Fig. 35); median lobe of aedeagus as illustrated (Fig. 17). FEMALE: tergite 8 moderately elongate and truncate apically, base not sinuate (Fig. 36); sternite 8 widely arcuate apically, base not sinuate (Fig. 37); spermatheca with capsule tulip-shaped and stem coiled posteriorly (Fig. 18).

Bionomics. The specimens were found by sifting forest litter in May.

Comments. The shape of the median lobe of the aedeagus and the spermatheca of are different from all recorded species of Nearctic , and they are generally similar to those of the Palaearctic species Gravenhorst, which is brown and has a much broader body.

Two additional Amischa morphotypes were recognized in the Yukon material on the basis of external body characters and the shape of the spermatheca. They are not included in this account because they are difficult to associate with any of the recorded species. The first morphospecies is represented by three narrowly elongate bicoloured specimens with the head and 4–5 basal abdominal tergites almost black, with the pronotum brown and the appendages and posterior of the elytra light brown, and with the spermathecal capsule moderately elongate with a moderately long apical invagination. The second morphospecies is represented by three specimens, which are broader, with the body uniformly dark brown to almost black, and the spermathecal capsule broader and shorter apically and with a longer apical invagination. Both groups have the apex of tergite 8 deeply notched. We need more specimens and representatives of both sexes to establish the status of these morphotypes.

The specific name derives from the name of the type locality, which is Whitehorse, Yukon.

Body narrowly oval, dark brown to black, with bases of antennae and legs rust-brown, surface matte, with asperate dense punctation on forebody and strong meshed microsculpture (Fig. 6); length 1.9–2.0 mm; head narrower than pronotum and elytra, with short postocular area, eyes large and slightly protruding; antennae slender, slightly incrassate apically, article 4 subquadrate, 5 slightly elongate and 6–10 slightly to strongly transverse; pronotum strongly transverse and broadest in the middle; elytra transverse, longer than pronotum; abdomen broadly arcuate laterally (Fig. 6). MALE: tergite 8 transverse and truncate apically (Fig. 40); sternite 8 widely rounded apically (Fig. 41); median lobe of aedeagus with venter of tubus straight and short, and apex sharply produced (Fig. 20). FEMALE: tergite and sternite 8 truncate apically (Figs 42, 43); spermatheca with pipe-shaped capsule and long stem hooked posteriorly (Fig. 21).

This species is similar externally to Bernhauer and Thomson but differs in the shape of the spermatheca and median lobe of the aedeagus, and has a broader body than the latter species.

This native Nearctic species is known only from the type locality in the Yukon Territory.

Adults were captured by sifting soil in a black spruce stand.

The specific name derives from the word micro, meaning small, and elytra,in allusion to the small and short elytra of this species.

Body narrowly subparallel; dark brown, with bases of antennae and legs rust-brown; strongly glossy, with fine and moderately dense punctation on forebody and strong, meshed microsculpture (Fig. 7); head as wide as pronotum and elytra, with long postocular area, eyes moderately small and slightly protruding; antennae slender, slightly incrassate apicad, articles 4–5 subquadrate and 6–10 slightly to strongly transverse; pronotum narrower at base and broadening apicad; elytra transverse, shorter than pronotum; abdomen widest subapically; length 1.9–2.0 mm (Fig. 7). MALE: tergite 8 truncate apically and with crenulation scarcely visible (Fig. 44); sternite 8 widely rounded apically (Fig. 45); median lobe of aedeagus with apex narrow and ventrally produced, athetine bridge well developed (Fig. 22). FEMALE: tergite 8 truncate apically (Fig. 46); sternite 8 truncate and slightly emarginate medially (Fig. 47); spermatheca with pipe-shaped capsule and long, posteriorly-coiled stem (Fig. 23).

This species bears some superficial external similarity to and but has typical -like genitalia.

Canada, Yukon, Watson Lake, Watson Creek, 60.12723, -128.8053, 16.VIII.2007, 697 m, mushrooms, B. Godin (LFC) 1 female.

The name of this species derives from the Latin adjective riparius, -a, -um,in allusion to the wet litter where the types were found.

Body small and narrow, subparallel; black, with tarsi reddish-brown; moderately glossy, with fine, dense punctation and meshed microsculpture on forebody (Fig. 8); head approximately as wide as pronotum, depressed medially, eyes slightly protruding; antennae slender, slightly incrassate apicad, articles 4–10 slightly to strongly transverse; pronotum emarginate laterally; elytra broader and longer at suture than pronotum; head, pronotum and base of abdomen of the same width; sides of abdomen subparallel; length 1.9–2.0 mm (Fig. 8). MALE: tergite 8 truncate apically and with smooth margin (Fig. 48); sternite 8 widely rounded apically (Fig. 49); median lobe of aedeagus with apex narrow and ventrally produced (Fig. 24). FEMALE (non-paratype): tergite 8 truncate apically (Fig. 50); sternite 8 broadly rounded apically (Fig. 51); spermatheca slightly distorted but with club-shaped capsule and posteriorly-twisted stem (Fig. 25).

This species differs from other Nearctic by the combination of body shape, strongly punctate surface and the shape of the median lobe of the aedeagus and spermatheca.

Distribution. This native Nearctic species is known only from the Yukon Territory but it is probably more widely distributed in northern Canada.

Bionomics. The two males were captured in September in wet, organic litter and the female was found in mushrooms in mid-August.

This species name derives from the specific name larsoni ( Klimaszewski and Langor), and the prefix pseudo (false) in relation to the similarity of the two species in external and, to a lesser degree, genitalic morphology.

Body narrowly subparallel, uniformly black or black with legs and sutural part of elytra reddish-brown (Fig. 9); moderately glossy, with fine, dense punctation and meshed microsculpture on forebody; head round, distinctly narrower than pronotum, with eyes as long as postocular region of head; antennae slender with articles 4–5 elongate, 6–10 subquadrate to slightly transverse; pronotum slightly transverse and almost as wide as elytra; elytra at suture as long as or slightly longer than pronotum; length 2.9–3.0 mm (Fig. 9). MALE: tergite 8 widely arcuate apically (Fig. 52); sternite 8 elongate and rounded apically (Fig. 53); median lobe of aedeagus with apex triangularly produced in lateral view (Fig. 26).

Female. tergite 8 truncate apically (Fig. 54); sternite 8 produced medially (Fig. 55); pygidium with ventral structure weakly sclerotized.

This species is known only from Whitehorse and Watson Lake in the Yukon Territory.

Bionomics

. This species was collected in May and June from ground litter.

is similar in both external morphology and genitalia to Klimaszewski and Langor. However, it may be distinguished from by the smaller and darker body, quadrate or transverse antennal articles 4–10 and by the median lobe of the aedeagus with a more elongate apical part of the tubus in lateral view.
