Description
Summary:Centromerus cornupalpis O. Pickard­Cambridge 1875 (Figs 17–20) Material examined.— Canada: Québec: Roussillon, Châteauguay [45°23’N, 73°45’W] 21.x.2000, sifting lichens, 3ɗ 1Ψ, C. Chantal (CPAD). 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). 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). 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. ... : Published as part of Paquin, Pierre & Dupérré, Nadine, 2006, The spiders of Québec: update, additions and corrections, pp. 1-37 in Zootaxa 1133 on page 12, DOI: 10.5281/zenodo.273386 ...
