diagnosis
Diagnosis. — Males are recognised by the shape of the paracymbium (P) (Fig. 17) and radix (RA) (Fig. 18), and the presence of a long proximodorsal horn (arrow) on the cymbium (Fig. 17). Females are distinguished by a narrow, smooth constricted scape (SC) that originates anteriorly to the posterolateral corners of the epigynum (Fig. 19).
discussion
Remark. — Helsdingen (1973) reported that males of the species are mature in winter time. Such climatic conditions are most probably similar to those observed in Québec in late October when the present collection was done.
distribution
Distribution. — Widespread in eastern North America, from Nova Scotia and Newfoundland to Tennessee and South Carolina. The species is also reported from Utah and Wyoming (Helsdingen 1973, Buckle et al. 2001).
