Zodarion rubidum Simon 1914

( Figs 80–84 )

Material examined.— Canada: Québec: Sainte­Anne­de­Bellevue, Morgan Arboretum [45°27’N, 73°57’W] 21.vii.2003, Macdonald campus Agricultural farm, disturbance AGR­C­3, pitfall, 1ɗ, C. Buddle (LEM)

Diagnosis.— Both sexes are recognised by the anterior median eyes (AME) being twice the diameter of other eyes ( Figs 80–81 ). Males are characterised by the palp bearing modified apical setae on the cymbium (arrow, Fig. 82 ) and the shape of the RTA ( Fig. 83 ). Females are recognised by the weakly sclerotized epigynal plate ( Fig. 84 ), and the configuration of the copulatory openings (CO) ( Fig. 84 ).

Distribution.— Palearctic. May be introduced into North America. The species is known only from isolated records in Colorado, Pennsylvania and Québec (present record) ( Ubick & Craig 2005).

Remark.— The establishment of the species in Québec remains uncertain. This record however suggests that it could be a resident of the East Coast. This species is the only Zodariidae known from the east Coast of North America.
