Description

Found in collected mushrooms

Keyed out using Chris Buddle's (2010) key http://cjai.biologicalsurvey.ca/b_10/b_10.html

  • All legs with 6 segments
  • Tarsus divided into 2 parts
  • Inner margin of movable finger of chelicera is dentate
  • Pleural membranes of abdomen granulate
  • Cheliceral galea present
  • Galea is single

This identifies it as a Globocreagris, Microcreagris, or Americocreagris. Americocreagris is blind, as is the Microcreagris species that occurs near BC (M. tacomensis). This species has eyes, so it is probably Globocreagris.

There are only two species of Globocreagris: G. theveneti and G. nigrescens. G. nigrescens has stumpier legs, so I think this is G. theveneti.
