ZooKeys 22: 19-33 doi: 10.3897/zookeys.22.177 Abstract The second survey in 2008 of rove beetle species from Stanley Park, Vancouver, British Columbia, Canada is presented. Fifty-one species were found from the following subfamilies: Aleocharinae (18), Micropepli- nae (1), Omaliinae (11), Osoriinae (1), Oxytelinae (2), Paederinae (1), Proteininae (2), Pselaphinae (3), Steninae (1), Staphylininae (8), and Tachyporinae (3). All species are listed in Tables 1 and 2. Thirty-five species were previously recorded from the storm-undamaged sites in 2007, including 16 species that were site-specific. Fifty-one species are reported from the storm-damaged sites, including 31 species that are site- specific. There are 19 species in common between storm-damaged and undamaged sites. Sixty-seven species of rove beetles are now known from all the sites studied in Stanley Park. One new species, Sonoma squam- ishorum Chandler & Klimaszewski, sp. n., is described and illustrated. Proteinus collaris Hatch is recorded from Canada and British Columbia for the first time. Four adventive aleocharine species are recorded. Copyright John A. McLean et al.

McLean et al / ZooKeys 22: 19-33 (2009) Keywords British Columbia, Canada, Coleoptera, new species, Staphylinidae, Stanley Park, survey, Vancouver Introduction This is the second paper devoted to rove beetles from Stanley Park. It includes species from samples collected in the storm-damaged forest in December 2006 (Figs. 1, 2 A-D). The first paper described species collected in 2007 from portions of the forest undam- aged by the storm (McLean et al. 2009). The purpose of this paper is to compare the rove beetle fauna in the storm-damaged areas surveyed in 2008 with the 2007 collection from the undamaged forest, and to describe and document a new species of Pselaphinae. Study locations The 2008 study sites included a stand west of the South Creek Trail (49°18'03”, 123°08'25"W) (Fig. 1, Site C) which had been burnt over in a fire in 1860. The high stumps (Fig. 2C) are a remnant from that period. ‘The site was cleared of all fallen trees STAMLDY PARK res lL abe (2008) ot ai Fe ag ere SEE ESEMER sentocm Site A: Aquarium STANLEY PARK BLOYOCAT RECOVERY m | ie 4 PE ge he WL GE es RS eb ae SEE de Ay Cent Ga TW SP ay trae 4 _—— 7 i. i See 4 7 : d Pry Ce ame ak eg ar a ts re " os rey om zl 7 5 aa P a eed Os ate faa a rad Be are a * in es nee , 4, 4 a — 4 ft = ao ; Fi +s ep pa rl a ai aN ‘ | an l in _ 4 “| C 4 [ co — L ies | ¥ # 1 7 i Figure |.

Part 2 2) and replanted in the fall of 2007 with clumps of Douglas-fir (Pseudotsuga menziesii (Mirbel) Franco) and western red cedar (Thuja plicata Donn ex. D. Don). The second 2008 study site was along Merilees Trail (Fig. 1, Site D) (49°18’40"N, 123°09'02"W) which has also been cleared and replanted with the same plant regime as Site C (Fig. 2D). The 2008 sites were much more open than the “intact” 2007 sites. Material examined More than 466 adult rove beetles were examined, and most aleocharines and pselap- hines 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. Traps were set out on April 23, 2008 and collected monthly through October. At each site, five Lindgren multiple-funnel traps and a flight-intercept trap were set and a pitfall trap was placed near each of the hanging traps. Polypropylene gly- col was used in all traps for preserving captured insects. The Lindgren traps were baited with specific pheromones and/or ethanol or alpha-pinene lures. The pitfall traps were unbaited. The collecting periods for each species are shown in Table 1. Figure 2. Collection sites A-D. Site A: Aquarium (2007). Site B: Hollow Tree/Rawlings Trail (2007). Site C: South Creek Trail (2008). Site D: Merilees Trail (2008). 22 John A. McLean et al / ZooKeys 22: 19-33 (2009) The larger catches found in the hanging traps did not indicate any preferences of the staphylinid beetles for any of the semiochemical baits for bark beetles or wood borers. Trap catches were quite even among traps suggesting that the trap form and shape was consistent for all species.

Part 2 23 Etymology. ‘This species is named in recognition of the Squamish aboriginal people who are known to have lived in this area of Vancouver. It took until 2008 for the Musqueam, Squamish and Tsleil-Waututh, who traditionally used the land that is now Stanley Park, to be physically represented at the site. That has now been addressed with People Amongst the People, three gateways covered with designs in threes and multiples of three to represent the three aboriginal groups, a work created by Susan Point and her team of Musqueam carvers. Diagnosis. Body small for Sonoma; frontal sulcus of head Y-shaped; discal foveae deeply impressed and impressions continued posteriorly to antebasal sulcus. Males with gula prominent and setose; aedeagus with phallobase separated, parameres nearly symmetrical, penis simple. Description. Length 1.68-1.76 mm. Body light orange-brown (Fig. 6). Head about as long as wide; tempora broadly rounded and distinct; frontal sulcus deep, abruptly widened in apical half to nearly twice basal width, forming a thick “Y”, sul- cus about as long as wide, base of sulcus even with midpoint of eyes; vertexal foveae distinct, posterior to point even with hind margin of eyes; eyes with about 60 facets in both sexes. Pronotum with each discal fovea at anterior margin of slightly converging impressions that extend to antebasal sulcus, median antebasal foveae distinct, nude; antebasal sulcus broad between lateral constrictions, narrow beyond constrictions to nude lateral antebasal foveae. Elytra half again as long as pronotum; foveal pattern 4-2-4 (four foveae in sutural stria, four in discal sulcus, and two faint foveae in lon- gitudinal line between them, foveae difficult to see on dried specimens). Abdomen as long as elytra in dorsal view. Males with posterior portion of gular area transversely projecting and densely se- tose. Legs lacking modifications. Abdomen with complete microsetigerous line near apex of visible tergite 1 (morphological segment 4). Visible sternites 4-5 progressively more strongly medially impressed, fifth visible sternite with prominent oblique and posteriorly directed acute projections at lateral third of sternite, projections strongly setose and extending posteriorly for short distance over anterior portion of sternite 6; sternite 6 with loose cluster of elongate spines to each side of middle (Fig. 4). Aedeagus of general form of Sonoma grandiceps Casey (Fig. 3); parameres with apical portions symmetrical, bases appearing slightly dissimilar, with coarse punctation on lateral por- tion of bases; penis elongate and of nearly even width in apical two-thirds, slightly asymmetrical. Females with gula slightly convexly curved, lacking dense setae. Abdomen with ster- nite 6 symmetrical, apex broadly and shallowly curved, with small granulate raised area at middle slightly projecting posteriorly (Fig. 5); sternite 7 flat and granulate (Fig. 5). Distribution. Only known from Stanley Park in Vancouver, British Columbia. Collection and habitat data. Both specimens were collected with funnel traps, and so the preferred habitat of this species is unknown. However, this collecting tech- nique is particularly effective in trapping species that are associated with downed, dead, or dying trees, and the suspected habitat is in rotting wood. Several species of this 24 John A. McLean et al / ZooKeys 22: 19-33 (2009) Figure 6. Sonoma squamishorum, dorsal view (holotype). Apical part of abdomen removed.

Comments. Sonoma squamishorum appears to be closest to S. grandiceps Casey, 1893, known only from the type series taken in Santa Cruz, California in the late 1800's, and S. tehamae Chandler, 2003, known only from a single site in northern California. The males of these species share a strongly basally-constricted phallobase, nearly symmetrical parameres with a row of long setae, and a densely setose and promi- nent gula. Sonoma grandiceps is the most similar species based on aedeagal form and the prominent setose projections of the fifth abdominal sternite, and is separated from S. squamishorum by the slightly asymmetrical apices of the large curved spine of each paramere, and the lack of the coarse lateral punctation of the parameres found in S. squamishorum. The apical portion of the penis is slightly more asymmetrical in S. gran- diceps, and S. tehamae has a much more asymmetrical penis, and lacks the apical curved spines of the parameres and the setose projections of abdominal sternite 5. Faunistic account - results and discussion This paper treats rove beetles captured from storm-damaged sites in Stanley Park, Vancouver, British Columbia, Canada. Collecting yielded 51 rove beetle species in the following subfamilies: Aleocharinae (18), Micropeplinae (1), Omaliinae (11), Osoriinae (1), Oxytelinae (2), Paederinae (1), Proteininae (2), Pselaphinae (3), Staeninae (1), Staphylininae (8), and Tachyporinae (3). All species are listed in Ta- bles 1 and 2. Sixty-seven species of rove beetles in total are reported from all stud- 26 John A. McLean et al / ZooKeys 22: 19-33 (2009) ied sites (A-D) (Table 1). Thirty-five species (52.2% of the total from sites A-D) were previously recorded from the storm-undamaged sites (Fig. 2A, B, Table 2), including 16 species (23.8% of the total from sites A-D) which were site specific (not found in the second survey) (McLean et al. 2009). Fifty-one species (76.1% of the total from sites A-D) are herein reported from the storm-damaged sites (Fig. 2 C, D), including 32 species (47.7% of the total from sites A-D) site specific (Ta- bles 1, 2). There are 19 species (28.3% of the total from sites A-D) shared between storm-damaged and undamaged sites (Table 2). The substantial increase in number of species at sites C and D was to be expected because the storm damaged areas of the forest provide a more diversified habitat. There is more forest edge, some frag- ments of an old forest, more dead snags and logs, and many disturbed soil habitats providing opportunities for a greater species diversity of rove beetles. The species composition is different in the AB and CD sites, except for the 19 species (28.3%) which are in common (Table 2). There are differences between the dominant spe- cies in the studied sites (Table 2). Atheta cheersae Klimaszewski, a common species in disturbed forest, was not found in the undisturbed forest, Atheta ventricosa Bernhauer occurred in smaller numbers in disturbed forest; Leptusa gatineauensis Klimaszewski and Pelletier was better represented in disturbed areas of the park; and Oxypoda stanleyi Klimaszewski and McLean was more numerous in undis- turbed forest. Stictalia brevicornis Casey was numerous in disturbed sites but was not found in the undisturbed sites where Stictalia californica Casey was present. Deinopteroloma subcostatum (Maklin), Eusphalerum pothos Mannerheim, and Oro- pus striatus (LeConte) were more numerous in the disturbed sites. Actium retrac- tum Casey, Sonoma squamishorum sp. n., Gabrius forcipatus (Hatch), Pelecomanium testaceum (Mannerheim), and Tachinus maculicollis Maklin occurred only in the disturbed sites and Deinothenarus pleuralis (LeConte) only in undisturbed sites. Clearly different rove beetle species appear to prefer different habitats. There are many singletons present only at either site. Additional adventive species, Xantholi- nus linearis (Olivier), 1 female, and Atrecus macrocephalus (Nordmann), 1 female, were reared from logs collected in the park but are not included in the tables and are excluded from our calculations. Proteinus collaris Hatch is recorded from Canada and British Columbia [Stanley Park] for the first time. Three adventive aleocharine species are recorded from the storm- damaged sites (B and/or C) are: Aleochara curtula (Goeze), Mocyta fungi (Gravenhorst), and Oxypoda opaca (Gravenhorst). The adventive species Aleochara fumata (Graven- horst) and Dalotia coriaria (Kraatz), previously recorded from storm-undamaged sites, are not recorded from storm-damaged sites, and A. curtula was not recorded from the undamaged sites. Klimaszewski and Winchester (2002) published the first comprehensive survey of aleocharine beetles from the ancient Sitka spruce forest in Carmanah Valley on Vancouver Island, British Columbia. They recorded 40 species, including 10 spe- cies new to science, in nine different tribes: Aleocharini (3 sp.), Athetini (20 sp.), Autaliini (1 sp.), Homalotini (5 sp.), Hypocyphtini (1 sp.), Lomechusini (1 sp.), Survey of rove beetles from Stanley Park. Part 2 ZT Myllaenini (1 sp.), Oxypodini (5 sp.), and Placusini (3 sp.). In the Stanley Park survey, only 25 species of aleocharines were recorded in five tribes: Aleocharini (2 sp.), Athetini (15 sp.), Homalotini (3 sp.), Oxypodini (2 sp.), and Placusini (3 sp.). Species from the tribes Autaliini, Hypocyphtini, Lomechusini, and Myllaenini were absent from Stanley Park. The dominant group at both study sites was Athetini with 20 species captured in Carmanah Valley and 15 in Stanley Park. There were 8 species in common between the two sites but no adventive species were recorded from the Carmanah native forest. Table |.
