An annotated systematic list of the potentially rare and endangered freshwater and terrestrial invertebrates in British Columbia /

Abstract

This paper provides an annotated systematic list of the endemic and potentially rare and endangered freshwater and terrestrial invertebrates in British Columbia. A total of 168 endemic species are listed, and 447 of the species that occur only in British Columbia in Canada are included. In addition, 203 of the more widely distributed species are listed as potentially rare and endangered in the province, mostly on the basis of limited occurrence or restriction to obviously endangered habitats or ecosystems.The list is based on published information, and information provided by systematic experts.Museum collections were not examined, so additions and correction to the list are expected. Additional study and research is suggested.Recent checklists of the spiders in B.C. (West et al. 1984(West et al. , 1988, record 571 species from keys have been published by Balogh & Balogh (1992).Keys to other families of terrestrial mites are to be found in Kethley (1990), Krantz &Ainscough ( 1 990) and Philips ( 1 990). Families of freshwater mites are considered by Smith & Cook (1991).The ticks in Canada have been monographed by Gregson (1956). None of the species in B.C. is rare or endangered. However, 1 2 species of watermite and 7 terrestrial mites are considered to be rare and perhaps endangered.Order ACARIFORMES Suborder PROSTIGMATA Family Tydeidae ** Meyerella marshalli Andre Endemic to B.C. Recorded from soil near Kamloops (Andre 1980). Family Hydryphantidae * Cowichania interstitialis Smith In Canada, recorded only from a spring beside South Shore Road, 2.3 km north of Cowichan L. (Smith 1983a). Elsewhere reported from Oregon. ** Tadjikothyas sp.n.A new species, endemic to B.C., and known only from a spring above the ski area on Mt. Baldy, near Bridesville (Smith 1991).* Tartarothyas sp.n.A new species, in Canada recorded only from two localities on Vancouver I.: a small stream beside Hwy. 1 8, 2.3 km E. of Cowichan L. turnoff; small stream beside Harris Cr. Main, east of Lizard L. (Smith 1991). Also known from Oregon and California.Family Anisitsiellidae * Bandakiopsis fonticola SmithIn Canada, recorded from near Clinton (spring at Loon Cr. Fish Hatchery), and Family Pauropidae * Allopauropus broelemanm Remy In NorA America, recorded only from a Douglas-fir forest near Shawnigan L.

Aquatic invertebrate species of concern on USFS Northern Region lands /

“…Originally described from Glacier Park, Logan Pass, Montana (Denning, 1949;Newell and Potter 1973), but subsequently found in Manitoba and British Columbia (Mt. Revelstoke National Park) (Nimmo and Scudder 1978;Scudder 1994).…”

Grasslands: biodiversity hotspots for some arthropods in British Columbia

“…Georeferenced distributional data were assembled for the rare species of terrestrial arthropods listed in Scudder (1994), as well as a few additional species added to this list since 1994. The distribution data for butterflies were obtained from the Butterflies of Canada database, supplemented by additional data from local lepidopterists.…”

Chrysopidae of Canada and Alaska (Insecta, Neuroptera) : revised checklist, new and noteworthy records, and geo-referenced localities

“…All specimens reported here are documented with data in Garland (1982), or as new records (above). This is one of five species of Chrysopidae that have been designated as potentially rare and endangered in British Columbia (Scudder 1994). Larvae of this species have been described (Smith 1922, as Chrysopa perfecta).…”

“…British Columbia, with 18 species, has the highest chrysopid diversity of any part of Canada. Indeed, among the 24 species of Chrysopidae in Canada and Alaska, eight can be found only in the Province of British Columbia, and five of these have been designated as potentially rare and endangered there (Scudder 1994). The first authenticated records are summarised for each species in Canada (Table 3), and Alaska (Table 4).…”
