Tetragnatha guatemalensis O. Pickard­Cambridge 1889

( Figs 53–57 )

Material examined.— Canada: Québec: Brome­Missisquoi, Saint­Armand [45°02’N, 73°03’W] 21.viii.1999, beating near lake, 4ɗ 1Ψ, N. Dupérré ( CPAD).

Diagnosis.— Males are recognised by the slender curved tip of the conductor (C) ( Fig. 55 ) and the laterally angled paracymbium tip (P) ( Fig. 56 ). Females are diagnosed by the shape of the spermathecae ( Fig. 57 ).

Distribution.— Known in north­eastern North America from Québec (this record) and Nova Scotia to southern California and Florida, Panama and the West Indies (see Dondale et al. 2003).

Remark.— The occurrence of the species in Québec was suspected by Hutchinson & Bélanger (1994), but was not included in Paquin & Dupérré (2003). Levi (1981) lists ’trail near marsh’ as a potential habitat for the species, which is more or less corroborated by the present record.
